Care and Safety

Your T20 was designed to fulfill any warranty obligations and to enjoy this product for many years. As for all the electronically devices, we recommend you to follow this few suggestions:

• Do not attempt to open the unit. Non-expert handling of the unit may damage it and/or annul the warranty.
• When using regulated power supply, take notice of power voltage that must be 5V to avoid damages.
• High temperatures can shorten the life of electronic devices, and warp or melt certain plastics. Do not store the radio in dusty or dirty areas.
• Keep the Radio dry. Rainwater or damp will corrode electronic circuits.
• If it appears that the Radio diffuses peculiar smell or smoke, please shut off its power immediately and take off the charger or battery from the Radio.
• Do not transmit without antenna.
• 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.

Hazardous Environments

Do not operate the radio in hazardous environments. An 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.

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 radiofrequency 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.

Programming software (optional)

Thanks to the Programming software CPS-T20-FRS, it is possible to increase the performance of your radio or to reduce its functionality by disabling some of the default features (CTCSS, DCS, TOT, VOX…) For further information, please consult the Programming software manual. Any attempt to change frequencies or output power of the radio invalidates the approval.

BATTERY RECHARGE

T20 is equipped for using a 3,7V Li-ion rechargeable battery pack which can be recharged by connecting the USB cable to the radio and to a USB charger (5V- 1A). It takes 5 hours to fully recharge the radio. For maximum battery life, we recommend charging the battery pack when the T20 is off and the battery pack is fully discharged. The Battery power-saving feature enables a reduction in consumption of up to 50%. If it has been set, it automatically activates when the transceiver does not receive any signal for more than 5 seconds in order to save the battery life. The Power saving function is activated by default and can be modified only by software.
Note : Using a different battery charger other than the one specified can cause damage to your device or may even cause explosions and personal injuries.

GETTING ACQUAINTED

NOTE : Long press the [Channel down] key to enter the monitoring state.

OPERATIONS

Power on/off and volume adjustment
Rotate the Power/Volume knob clockwise to turn the radio on. Rotate the control clockwise /counter-clockwise to adjust the volume level as you prefer. To turn the radio off, rotate the control counter-clockwise till hearing a mechanical “click”.

Channel selection
In standby mode, directly press the Channel Up (+)/ Down(-) key to step down or down to select the channel. When the voice prompt function is turned on, the corresponding channel is broadcast by voice. With T20 turned on, long- press the LAMP key to lock or unlock the channel selection function. After the channel selection function is locked, channel switching will be prohibited, and pressing the Channel Up (+)/ Down(-) keys will cause a prompt tone to prohibit operation.

Transmission
To communicate, all radios in your group must be set to the same channel. Briefly press the Channel Down (-) to enable the Monitor feature in order to make sure that the frequency is not busy, and then press the [PTT] key. Release the [PTT] key to receive. Only one user at a time can talk during radio communications. Therefore, it is important not to transmit when you are receiving communication and use the transmission mode sparingly to allow other users to talk. Transmission consumes a significant amount of energy and should therefore be used sparingly to prolong the battery life. If you are unable to contact a station that you have no problems in receiving, the station may be using CTCSS tones or DCS codes.

Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to listen to signals that are too weak to keep the Squelch permanently opened. Hold down the Channel Down (-) to enable such function.

VOX
The VOX feature enables hands free conversations without using PTT: just speak in the direction of the microphone and the communication will be automatically activated. The VOX sensitivity can be adjusted in 5 different levels (1…5) through the programming software: Level 2 is set by default and has the lowest VOX sensitivity, 5 is the lowest one. With the programming software you can enable/disable the VOX feature and select the sensitivity levels. CPS programming path: Edit > VOX > VOX Level

Scan
To enable the Scan function, all 22 channels must be programmed. If you turn on the radio on channel 22, the scanning will automatically start. Whenever any signal is detected, the scanning will stop on a busy channel. If the PTT is pressed, you will transmit on the latest busy channel. Channel 22 is the priority channel; therefore if you don’t pick up any signal when you press PTT, the radio will transmit on channel 22. On the 16th channel, press and hold the PTT + Channel Down (-) to turn on the radio and turn the scanning function on or off. Repeat the above operation to turn off the scan function.

Squelch
The Squelch function suppresses noises on free channels and allows receiving even weak signals. T20 has 10 different Squelch levels that can be set by programming software: 0 means that the Squelch is turned off; from level 1 to level 9 you will have different levels of noise reduction. The higher is the level, the louder will be the Squelch. By default, the Squelch level of T20 is set on level 4. Make sure you do not set an excessively high squelch level because in this case you may not be able to receive weaker signals. On the other hand an excessively low Squelch value could enable the Squelch even when no signals are present. Squelch must always be adjusted when no signals are present. The Time Out timer is settable from 30 sec to 270 sec. only through the programming software. This feature is disabled by default.

CTCSS/DCS tones
CTCSS and DCS tones are similar to access codes and enable the radio to communicate only with the users that are tuned on the same channel and have set the same code. For each channel, you can set up to 50 CTCSS tones and 210 DCS codes. The CTCSS/DCS tones are a sort of “access codes” and enable the radio to communicate only with the other users set on the same frequency and on the same CTCSS/DCS tone. Undesired signals coming from other stations set on the same frequency but with different CTCSS/DCS tones won’t be received.

Quick operation radio
Without CPS programming software, you can perform the following quick operations through the combination of PTT + Channel Down (-):

• On channels 1, press and hold the PTT + Channel Down (-) key to turn on the radio and turn the VOX function on or off. Accompanied by a voice prompt VOX ON or VOX OFF.
• On the 15th channel, press and hold the PTT + Channel Down (-) to turn on the radio and switch the prompt language between Chinese and English.
• On the 16th channel, press and hold the PTT + Channel Down (-) to turn on the radio and turn the scanning function on or off.
