Please charge the battery before initial use or after long time storage. ● Repeat charging and discharging the battery 2 or 3 times and the battery would reach its maximum capacity, please replace or charge the battery when it is in low power. ● The quick consume of the power after normal charge shows exhaustion of the battery. Please contact your dealer and buy new approved battery. ● Time-out-timer The purpose of the Time-out-timer is to prevent any signal person from using a channel for an extended period of time. If the transmission continues beyond 10 seconds, the transceiver will stop transmission and give out alarms. To stop the alarms, please release the PTT switch and the transceiver will resume the state of standby. ● Battery Saving The radio would reduce its power consumption. If there is no signal or operation over 10 seconds, the battery saving function would be on automatically. When signal is received or with operation, the radio would switch to normal mode. ● Low Battery Warning When the voltage fall down to lowest level, the tone of “Please 04 Get Acquainted Function Description Case PortBattery Port 05 Charge” will sound, required to replace battery or recharge the battery. ● Monitor This function can be realized by the long press of the default key. Press the monitor key, the Signal Indicate will change to Green. ● QT and DQT This function mainly uses to avoid irrelative calling in caertain channel. With this function, users can receive calling in corresponding channels only with the same QT/DQT. ● VOX Function VOX is a function that voice can be launched without pressing the PTT key,operation details:Operation detailsSwitch to channel 7 first, then turn off the radio. Press“CH+”key, turn on the radio at the same time. There will be a voice "VOX ON" or "VOX OFF".

RF energy, which when used improperly, can cause biological damage. All Retevis two-way radios are designed, manufactured, and tested to ensure they meet government-established RF exposure levels. In ad- dition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following websites for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits: http://www.who.int/en/ Local Government Regulations When two-way radios are used as a consequence of employment, the Local Government Regulations requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information. Your Retevis two-way radio has a RF Exposure Product Label. Also, your Retevis user manual, or separate safety booklet includes information and Warnings 07 Before using this radio, read this guide which contains important operating instructions for safe usage and RF energy awareness and control for compliance with applicable standards and regulations. operating instructions required to control your RF exposure and to satisfy compliance requirements. Radio License Governments keep the radios in classification, business two-way radios operate on radio frequencies that are regulated by the local radio management departments (FCC, ISED, OFCOM, ANFR, BFTK, Bundesnetzagentur...).To transmit on these frequencies, you are required to have a license issued by them. The detailed classification and the use of your two radios, please contact the local government radio management departments. Use of this radio outside the country where it was intended to be dist- ributed is…
