squelch level

The squelch level is an analog reference level used to set the internal squelch threshold in the intercom CPU. You can preset the squelch level. When in user mode, you can adjust the squelch level. Range: 0 (Squelch On) – 9 (Deep) (in steps of 1). power saving feature

Power saving
Turn it on for 10 seconds without any operation, and automatically enter the power saving state. Tune OFF The intercom does not save power.

Scanning Switch
Talking on 16 channels, the intercom will automatically detect the activity of the channels defined as sweepable channels in channels 1 to 15 (the frequency writing software can define whether each channel is sweepable or non-swept), and when there is a signal on the channel being scanned, the intercom will automatically stop on that channel to talk. The walkie-talkie will stop on the channel with the signal, and when the signal disappears after another 15, it will continue to scan the next channel. When there are fewer than 2 scannable channels, the pair of feeders cannot be scanned. acoustic emission

The walkie-talkie is set by the frequency writing software to have the voice control function turned on, and can be connected to the walkie-talkie through a headset to set the voice control gain level and speaking volume to transmit signals.

• Voice control is only effective if the voice control function is turned on.
• Sound Gain Level: The VOX automatically transmits when the sound level is higher than the set sound gain level. The gain level is adjustable from 1 to 9 levels.
  (Note: the voice-activated gain level must be set by the frequency writing software)

Battery Voltage Detection

Low battery alarm: When the voltage is lower than a certain level, about every 20S voice prompts “please charge” launch invalid. timeout timer The frequency writing software can be set up to transmit time 15s~600s timing limit.

Chinese/English conversion
The frequency writing software can be set in Chinese, English, off three kinds of states.

Subaudio QT/Digital Subaudio DQT
Subaudio QT/Digital Subaudio DQT signalling can be set on the intercom’s channel using frequency writing software. When sub-audio or digital subaudio signalling is set on a channel, squelch can only be turned on when a signal is received using the same subaudio or digital subaudio. If the same channel is called using a different QT/DQT, the squelch cannot be turned on and only lights green. The sub-audio QT/Digital Subaudio DQTs are listed below:

Subaudible QT: (39 total)

Digital Subaudio DQT: (166 total)

scrambler function
In the walkie-talkie Frequency Writer Software menu in the scrambler set the “Yes” scrambler function is open, and set “No” is closed, if one party opens the scrambler, the other party does not open, the walkie-talkie will emit a sound similar to the the the robot if you open at the same time is a normal sound, to prevent third-party monitoring. Prevent third-party listening.

TYPE-C charging function
Open the headphone cover and insert the TYPE-C charging cable to charge the unit. Red light when charging, green light when fully charged.
Note : Please turn off the walkie-talkie when charging. If the green light is on when the charging cable is just inserted, please measure whether the battery is in good contact with the machine’s power base.

FCC STATEMENTS WARNING AND COMPLIANCE STATEMENT

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, and(2) this device must accept any interference including received interference that may cause undesired operation. The grantee is not responsible for any changes or modifications not expressly approved by the party responsible for compliance. Such modifications could void the user’s authority to operate the equipment. Replacement of any transmitter component (crystal, semiconductor, etc) not authorized by the FCC equipment authorization for this radio could violate FCC rules.

WARNING
MODIFICATION OF THIS DEVICE TO RECEIVE CELLULAR RADIOTELEPHONE SERVICE SIGNALS IS PROHIBITED UNDER FCC RULES AND FEDERAL LAW.

This equipment has been tested and found to comply with the limits for a Class B digital device, under part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used by the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

RF Exposure Statement
Our radio generators RF electromagnetic energy during transmit mode. This radio is designed for and classified as ”Occupational Use Only” meaning it must be used only during employment by individuals aware of the hazards and the ways to Minimize Such hazards. This radio is NOT intended for use by the ”General Population” in an uncontrolled environment. This radio has been tested and complies with the FCC RF exposure limits for ”Occupational Use Only”.

In addition, our radio complies with the following Standards and Guidelines about RF energy and electromagnetic energy levels and the evaluation of such levels for exposure to humans: IEEE Std. 1528:2013 and KDB447498, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Concerning Human Exposure to Radio Frequency Electromagnetic Fields 3 kHz to 300 GHz. American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the

Measurement of Potentially Hazardous Electromagnetic Fields-RF and Microwave. The information listed above provides the user with the information needed to make him or her aware of RF exposure and what to do to ensure that this radio operates within the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, The radio generates RF energy that can cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft and blasting sites.

Occupational/Controlled Use

The radio transmitter is used in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. This device complies with RF radiation exposure limits set forth for an uncontrolled environment. Do not use this device when the antenna shows obvious damages. Hold this transmitter approximately 25 mm away from your face and speak normally with the antenna pointed up and away. Use the supplied belt clip for body-worn configuration as other accessories may not comply with the limits.
