Note: To get the best range from the external whip antenna(50 )should be used.Ω Ant: Tx GMRS, Rx: 136-174&400-490Mhz, 0dBi. installation is height < 3m.
Turn volume knob clockwise to increase colume and anti-clockwise to reduce it.
In standby states, press the microphpne key or front panel
key to switch between main channel and sub channel. The top left corner of LCD will display current main channel.
(Europe version only)

key to store the new frequency and return to standby.
» XXX stands for the channel number, if LCD displays "Null" under "Save TO XXX", means current channel is empty.
Choose a receiving channel or frequency for receiving call, if the RX signal is week, hold front panel key or microphone
key to monitor weak signal.
» When the RX icon and field strength flashes, but can not hear the calling, it means current channel receive a matching carrier but unmatching signaling. Refer to CTCSS/ DCS CODE or Optional Signaling setup).
Hold [PTT] and speak into microphone. the radio start transmit, the screen shows red TX and field strength. Hold the microphone approximately 2.5-5.0cm from your lips and speak to microphone in your normal speaking voice to get best timbre.
In standby, hold key, release it until the LCD displays ALARM, the alarm function turns on. Program emergency alarm rule shall be programmed by PC software.
