select [ON]+ [MENU] to confirm(Note: The factory default is off, it is generally not recommended to open);
5. Press [MENU] + 47+ [MENU] to enter RPT-TONE，then press the [UP] and [DOWN] keys (△▽) to select [ON]+
[MENU] to confirm(Note: The factory default is off)；
6. Place two Repeater radio at a distance of about 5 meters to prevent mutual interference. Long press RPT , the
icon on the top left of the screen to indicate that they are in the transfer state. At this time, the transmitter can be
used to talk to the receiver through the Repeater radio to talk.
4. Frequency/CTCSS detection: (Hold on PTT key of the scanned transceiver during the whole scanning
period, till the scan data is saved)
1. Press [MENU]+[*SCAN] to enter scan mode, Press [EXIT] or [A/B] key to exit scan mode. Rotate the channel
knob to select the scanned frequency. The scanned frequency range is VHF(136-174MHz)/UHF(400-520MHz)
2. Power on transceiver, install the antenna and hold PTT to transmit, the up line of the screen displays the fixedly
current frequency, the down line displays fixedly CTCSS/DCS .If the transceiver is not set CTCSS/DCS, the down
line displays nothing.
3. During scanning, the green LED flashes. When scanning the matched the frequency, the green LED stops
flashing. Press [UP]/[DOWN] keys to adjust frequency, in order to minimize the frequency difference, and improve
CTCSS/DCS currency and call clearness. Press [MENU] key to save the scanned data, which will replace the
current location information.
