Content of the packaging • 1 Radio • 1 Li-Ion Battery • 1 Adapter • 1 Type-C Cable • 1 Belt Clip • 1 lanyard • 1 Owner’s Manual If any item is missing, please verify with your dealer. Product Features 1. Power On/Off key • Press and hold the Power key for 3 seconds to turn on the radio. • Press and hold the Power key for 3 seconds to turn off the radio. 2. PTT key • Press and hold the PTT key to initiate a call, and the red indicator light will remain on. • Release the PTT key to return to receiving state, and the green indicator light will remain on during the receiving process. 3. Vol + key • Short press Vol+ key to increase the volume. 4. Vol - key • Short press Vol- key to decrease and decrease the volume. 5. Menu keys 5.1 short press menu key to enter menu list，long press menu key to Activate/Close the keyboard lock. 5.2 Group select: Select a group to initiate group calls. 5.3 Member select: Select a member to initiate a private call. Note: If there is no operation within 30 seconds, the Single Call status will be automatically exited. Or either party can manually exit the Single Call by press the BACK button and return to the original group call status. 6. Radio settings: 1. Card management: When two SIM cards are installed, you can choose to use the specified SIM card. 2. Power save mode: Normal mode, Power save mode, Super power save mode (default). Note: When in a weak signal environment and with poor call quality, you can choose power save mode or normal mode. The call quality will be improved, but the machine also consumes more power. 3. Automatic screen shutdown: If there is no button operation within the set time, the radio will automatically shut down the screen. 4. Transmit prompt sound: After enabling this function, press and releas the PTT key will emit a "beep" prompt sound, which will improve the call experience.

Keypad lock: When select menu to key lock, lock the keypad by long press the MENU key for 2 seconds, and the lock symbol will be displayed above the screen. When select automatic, the button will be automatically locked when the screen rest time is up (Note: The keypad lock function can only be used when the PTT key is available). 7. Single call exit time: refers to the maximum call time when enter the private call state. 7. Status Indications The top LED will help you to identify the current radio status. Status LED Indication Time Search Network Green light flashing fast Awaiting Green light flashing slowly 0.5S on, 3.5S off Transmitting Constant Red Receiving Constant Green Using earpiece（K type） Open the protective cover, insert the compatible earpiece, press the PTT key on the earpiece, and initiate a call. Release the PTT key to enter the receiving state. Battery charge To charge batteries in radio: 1. Insert the original adapter into the AC socket, and then insert the adapter cable into the C-shaped socket at the bottom of the radio. 2. The indicator light at the bottom of the radio turns red and will turn green when it completes charging. Installing SIM card Before using thisradio, insert a valid SIM cardinto the radio. Basic Operation On/off radio When the radio is turned off, press and hold the Power key for 3 seconds to turn on theradio. After successfully logging into the network, there will be a voice prompt with a slow green light flashing. • To turn off the 4G LTE POC RADIO, press and hold the Power key for 3 seconds. Adjust volume: When the radio is turned on, press the Vol+ key briefly to gradually increase the volume; Short press the Vol- key to gradually decrease the volume and adjust it to the appropriate level. Select a group (Group call) Short press menu key to enter the group list, press the key to browse the group: • Press the exit key to exit the group selection status, • Press the confirm key to confirm entry into the group. If you press the PTT key, you can initiate a call to the group (with a red light on), accompanied by a prompt sound and screen display. Select members (single call) Short press menu key to enter the member list, and press the key to browse members: • If you press the exit key, you can exit the member selection status • Press the confirm key to confirm the selection of the member. Now you can press the PTT key, a private call can be made to the member (with a red light on) accompanied by a prompt sound and screen display.
