Maintenance Your Two Way Radio is an electronic product of exact design and should be treated with care. The suggestions below will help you to fulfill any warranty obligations and to enjoy this product for many years. • Do not attempt to open the radio for any reason! The radio’s precision mechanics and electronics require experience and specialized equipment; for the same reason, the radio should under no circumstances be realigned as it has already been calibrated for maximum performance.

Charging Operation The battery is not charged at the factory, please charge it before use. Charge the battery for the first time after purchase or extended storage (more than 2 months) may not bring the battery to its normal operating capacity. After repeating fully charge/discharge cycle for two or three times, the operating capacity will reach the best performance. The battery life is over when its operating time decreases even though it is fully and correctly charged. Replace the battery.
NOTE: When charging a power-on transceiver equipped with battery, the LED will not turn into green to show the full charge status; it will be indicated only when you turn off the transceiver: because when the transceiver is turned on, it would consumes energy and the charger cannot detect when the battery has been fully charged.
Charging Prompt 1. Self-examination: When charging, ORANGE light twinkles for 1 second and goes out. That means the charger has passed its self-examination and it can charge the battery normally. If the light remains orange or the red light twinkles, which means the charger can not pass its self-examination or charge the battery. 2.
Installing / Removing the Li-ion Battery Match the two grooves of the battery pack with the corresponding guides on the back of the transceiver and push. 1. Press the battery pack and transceiver firmly together until the release latch on the top of the transceiver locks. After hearing a “click” sounds, the battery has been locked. 2. To remove the battery pack, slide the release latch and remove the pack away from the transceiver.

Basic Operations Turn the Radio On & Off In power-off state, please turn POWER/VOLUME clockwise to turn on the transceiver. In power-on state, please turn POWER/VOLUME anticlockwise to turn off the transceiver. Adjusting Volume In power-on state, turn POWER/VOLUME to adjust the volume. Clockwise-up, anticlockwise -down. When adjusting the volume, press the key programmed as Squelch Off to monitor the current volume firstly.
Frequency Adjusting When the transceiver is set in VFO mode or FM radio frequency mode, rotate the channel switch to set the frequency. Rotate the channel switch clockwise to increase the frequency, counterclockwise to decrease the frequency. Every rotate can add or reduce one stepping value. NOTE: Channel step:2.5K, 5K, 6.25K, 10K, 12.5K, 20K, 25K, 30K and 50KHz in total 9 for optional. FM radio step frequency is 50K.
Squelch Off Momentary / Squelch Off Side key PF2 can be setup for Squelch off Momentary or Squelch off function by programming software. 1. Squelch off: Press PF2; the squelch will be enabled and the background noise can be heard. Press PF2 again; the squelch will be mute. 2. Squelch off Momentary: Press and hold PF2; the squelch will be enabled and the background noise will be heard. Release PF2, the squelch will be mute.
Side Key PF1 function instruction 1. VOLT: Battery capacity inquiry: Under standby, press PF1, LCD displays current battery capacity, press this key again to exit. 2. CALL: Transmit the prestored DTMF/5TONE Encode signal in channel. 3. ALARM: Long pressing PF1, LCD display “ALARM”, transceiver will enable the preset alarm function. 4. SUBPTT: Press PF1, transceiver will transmit at sub-band frequency. 5.
Delete channel 1. Under standby state, press FUNC, the top left corner of LCD displays icon, press V/M to switch into channel mode, channel number flashes. 2. Rotate the channel switch to select the channel number you want to delete. icon, press and hold 3. Press FUNC, the top left corner of LCD displays V/M until the transceiver emits “DUDU” beep and clear up frequency information of current channel, deletion is successful. NOTE: This process can be applied for deleting FM radio channels.
