To help you ward off bodily injury or property loss that may arise from improper operation, please read all the information carefully before using our products. This contains instructions for safe usage and RF energy awareness and control for compliance with applicable standards and regulation.

Safety Information for Radios

Your wireless handheld portable transceiver contains a low power transmitter. When the talk button is pushed, it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for handheld wireless devices.

GETTING STARTED

Regulations and Safety Warnings

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired operation.

Important: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device. Your radio is set up to transmit a regulated signal on an assigned frequency. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. Any adjustments to your radio must be made by qualified technicians.

To be safe and sure:

• Never open your radio’s case.
• Never change or replace anything in your radio except the battery.

Your radio might cause TV or radio interference even when it is operating properly. To determine whether your radio is causing the interference, turn it off. If the interference goes away, your radio is causing it. Try to eliminate the interference by moving your radio away from the receiver. If you cannot eliminate the interference, the FCC requires that you stop using the radio.

Hazardous Environments: Do not operate the radio in hazardous environments. Explosion or fire may result. Do not operate the radio near unshielded electrical blasting caps. Under certain conditions, radios can interfere with blasting operations and may cause an explosion. Turn your radio OFF to prevent accidental transmission when in a blasting area or in areas posted: “Turn off two-way radio.” Construction crews often use remote control RF devices to set off explosives.

Care and Safety: To clean the radio, use a soft cloth dampened with water. Do not use cleaners or solvents because they can harm the body of the unit and leak inside, causing permanent damage. Use a dry, lint-free cloth to clean the battery contacts.

FCC STATEMENT

RF Exposure Information

WARNING:  Read this information before using the radio. In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters.

Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of the radio complies with the FCC guidelines and these international standards.
Never allow children to operate the radio without adult supervision and the knowledge of the following guidelines.

WARNING:  It is up to the user to properly operate this radio transmitter to insure safe operation. Please adhere to the following:

• Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the radio, or result in violation of FCC regulations.
• Do not use the radio with a damaged antenna.
• If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for a replacement antenna.

Hand-held Operation (Held-to-Face)

• This device was evaluated for typical hand-held (held-to- face) operations with a 1 inch spacing from the front of the radio.
• For hand-held operation, the radio should be held 1 inch from the user’s face in order to comply with FCC RF exposure requirements.
• For more information about RF exposure, please visit the FCC web site at www.fcc.gov.

Body-worn Operation

This device was evaluated for body-worn operations with the supplied belt-clip accessory. (All necessary accessories are included in the package; any additional or optional accessories are not required for compliance with the guidelines.) Third party accessories (unless approved by the manufacturer) should be avoided as these might not comply with FCC RF exposure guidelines.

For more information about RF exposure, please visit the FCC web site at www.fcc.gov.

GMRS Communication

This GMRS (General Mobile Radio Service) feature is a land-mobile service available for short-distance, two-way communications in the USA. You must have a valid FCC license to communicate on these channels. The GMRS/FRS frequencies that radio this radio uses are set aside for communicating with others while hiking, biking, and working; keeping track of family and friends at a crowded public event; checking with travel companions in another car; talking with neighbors; arranging meeting spots with others while shopping at the mall. Licensed users will be issued a call sign by the FCC, which should be used for station identification when operating this radio. GMRS users should also cooperate by engaging in permissible transmissions only, avoiding channel interference with other GMRS users, and being prudent with the length of their transmission time.

FCC License Required

This two-way radio operates on GMRS (General Mobile Radio Service) frequencies which require an FCC (Federal Communications Commission) license. A user must be licensed prior to transmitting on the GMRS band with this radio. Serious penalties could result for unlicensed use of GMRS channels, in violation of FCC rules. Operation of this radio is subject to additional rules specified in 47 C.F.R. Part 95. For licensing information and application forms, please call the FCC Hotline at 800418-FORM. Request form #159 and form #605. Questions regarding the license application should be directed to the FCC at 888-CALL-FCC. Additional information is available on the FCC’s website at www.fcc.gov.

NOTE: Even if you operate this radio on FRS (Family Radio Service) channels at low power (0.5 watt), you are required to have an FCC license. Because this radio operates in the 0.5 to 5 watt GMRS power range all GMRS rules apply and will require you have a GMRS license even for FRS (Family Radio Service) communication. Normal FRS only radios operate at a maximum power of 0.5 watt (500 mill watt) power and have an integral (non-detachable) antenna.

Replacement or substitution of transistors, regular diodes or other parts of a unique nature, with parts other than those recommended by our company may cause a violation of the technical regulations of part 95 of the FCC rules, or violation of type acceptance requirements of part 2 of the rules.

• Do not transmit without antenna.

BATTERY INFORMATION

Charging the Battery Pack

The Li-ion battery pack is not charged at the factory; please charge it before use. Charging the battery pack for the first time after purchase or extended storage (more than 2 months) may not bring the battery pack to its normal maximum operating capacity. Best operation will require fully charging/ discharging the battery two or three times before the operating capacity will reach its best performance. The battery pack life may be depleted when it’s operating time decreases even though it has been fully and correctly charged. If this is the case, replace the battery pack.

Charger Supplied

• Please use the specified charger provided by our company.
• Other models may cause explosion and personal injury. After installing the battery pack, and if the radio displays low battery with a voice prompt, please charge the battery.

Use Caution with the Li-ion Battery

• Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery pack, as our company cannot be held responsible for any accident caused by modifying the battery.
• The ambient temperature should be between 5℃-40℃ (40˚F – 105˚F) while charging the battery. Charging outside this range may not fully charge the battery.
• Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
• To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until the green light is on.
• Do not recharge the battery pack if it is fully charged. This may shorten the life of the battery pack or damage the battery pack.
• Do not charge the battery or the radio if it is damp. Dry it before charging to avoid damage.

WARNING

When keys, ornamental chain or other electric metals contact the battery terminal, the battery may become damage or injure a human. If the battery terminals are short circuited it will generate a lot of heat. Take care when carrying and using the battery. Remember to put the battery or radio into an insulated container. Do not put it into a metal container.

How to Charge

• Plug the AC adaptor into the AC outlet, and then plug the cable of the AC adaptor into the DC jack located on the back of the charger. The indicator light blinks orange and is then ready to charge a battery.
• Plug the battery or the radio into the charger. Make sure the battery terminals are good in contact with charging terminals. The indicator light turns to red— charging begins.
• It takes approximately 2-5 hours to fully charge the battery. When the lamp lights green, the charging is completed. Remove the battery or the radio unit with its battery from socket.

When charging a radio (with battery) the indicating lamp will not turn into green to show the fully charged status if the radio is powered on. Only when the radio is switched off will the lamp indicate normal operation. The radio consumes energy when it is power-on, and the charger cannot detect the correct battery voltage when the battery has been fully charged. So the charger will charge the battery in constant voltage mode and fail to indicate correctly when the battery has been fully charged.

LED Indicator

NOTE: Trouble means battery too warm, battery short-circuited or charger short-circuited.

How to Store the Battery

• If the battery needs to be stored, keep it in status of 80% discharged.
• It should be kept in low temperature and dry environment.
• Keep it away from hot places and direct sunlight.
  • Do not short circuit the battery terminals.
  • Never attempt to remove the casing from the battery pack.
  • Never store the battery in unsafe surroundings, as a short may cause an explosion.
  • Do not put the battery in a hot environment or throw it into a fire, as it may cause an explosion.

INSTALLATION OF ACCESSORIES

Before the radio is ready for use we need to attach the battery pack, as well as charge the battery.

Installing the belt clip

• At the back of the radio there are two parallel screws mounted above the battery, remove these and thread them through the holes on the belt clip as you screw them back into the radio body.
• Removing the Belt Clip: Unscrew counter-clockwise to remove the belt clip.

• key: Keep it pressed it for more than 2 seconds, the channel and frequency will move downwards rapidly; in SCAN mode, press this control to move the scanning downwards.

Numeric keypad

• With these keys you can input the information or your selections on the radio. In tx mode, push the number keys to send a corresponding DTMF code.

Key

• A short momentary press of the key enables the reverse function.
• If you press this button for more than 2 seconds you will lock/unlock the keypad.

BASIC OPERATIONS

Power on the radio

• Turning the unit on
  • To turn the unit on, simply rotate the volume/power knob clockwise until you hear a “click”. If your radio powers on correctly there should be an audible double beep after about one second and the display will show a message or flash the LCD depending on settings for about one second. Then it will display a frequency or channel. If the Voice prompt is enabled, the voice will announce “frequency mode” or “channel mode”.
• Turning the unit off
  • Turn the volume/power knob counter-clock wise all the way until you hear a “click”. The unit is now off.

Adjusting the volume

• To turn up the volume, turn the volume/power knob clock-wise.
• To turn the volume down, turn the volume/power knob counter-clock-wise. Be careful not to turn it too far, as you may inadvertently turn your radio off.

Channel selection

• There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
• For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode. However,
• Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also used for programming channels into memory.
• In Channel (MR) mode you can navigate up and down the channel by using the / keys or the encoder.
• Ultimately which mode you end up using will depend entirely on your use case.

Making a call

• Channel mode call: After selecting a channel, hold down the [PTT] key to initiate a call to the current channel. Speak into the microphone with normal tone. Initiate a call, the red LED is on.
• Frequency mode call: The off state, hold press [MENU] key to open the radio, switching to the frequency mode, the frequency range allowed entering, press the [PTT] key, a call to the current channel. Speak into the microphone with normal tone. Initiate a call, the red LED is on.
• Receive a call: When you release the [PTT] key, you can answer it without any action.
  • When receiving a call, the green LED is on.

NOTE: To ensure the best reception volume, keep the distance between the microphone and the mouth at the time of transmission from 2.5 cm to 5 cm.

Frequency (VFO) mode

In Frequency (VFO) mode you can navigate up and down the band by using the / keys. Each press will increment or decrement your frequency according to the frequency step you’ve set your transceiver to. You can also input frequencies directly on your numeric keypad with kilohertz accuracy. The following example assumes the use of a 12.5 kHz frequency step.

Example:  Entering the frequency 432.56250 MHz on display A

• In standby mode, switch to the frequency (VFO) mode.
• Enter [4][3][2][5][6][2][5] [0] on the numeric keypad.

◎In VFO mode, VFO will be displayed on the right. Any transmission is prohibited, and reception and scanning are allowed.
Among them, the scanning frequency can be accurately set.

WARNING: Just because you can program in a channel does not mean you’re automatically authorized to use that frequency. Transmitting on frequencies you’re not authorized to operate on is illegal, and in most jurisdictions a serious offence. However, it is legal in most jurisdictions to listen. Contact your local regulatory body for further information on what laws, rules and regulations apply to your area.

Channel (MR) mode

• The use of Channel (MR) mode is dependent on actually having programmed in some channels to use.
• Once you have channels programmed and ready, you can use the / keys or the encoder to navigate between channels.

◎In MR mode, the channel number will be displayed on the right. Among them, GMRS communication (CH1-CH30) allows transmission and reception. Channels other than CH01-CH30 can only be scanned and received, and transmission is prohibited.

ADVANCED FEATURES

TX 1000Hz, 1450Hz, 1750Hz, 2100Hz repeaters tone

• Press [PTT] + [LAMP/Monitor] to send 1750Hz repeaters tone. This function is useful for communications through repeaters.
• If you have the keypad lock enabled on your radio, you can still send a 1750Hz tone the regular way without having to unlock your radio.

Manual Programming (Channels Memory)

Memory channels are an easy way to store commonly used frequencies so that they can easily be retrieved at a later date. The radio features 199 memory channels that each can hold: Receive frequencies, group signaling information, bandwidth, ANI/ PTT-ID settings and a six character alphanumeric identifier or channel name 1 .

Frequency Mode vs. Channel Mode

In standby mode, press and hold the [VFO/MR] key to switch between frequency (VFO) mode and channel (MR) mode.
These two modes have different functions and are often confused.

• Frequency Mode (VFO): Used for a temporary frequency assignment, such as a test frequency or quick field programming if permitted.
• Channel Mode (MR): Used for selecting preprogrammed channels.
