Scan

Scan function can be used to monitor every channel.
Under the standby state, pressing the programmed "Scan" key,
transceiver emits "Du" beep and comes into scan state. It scans
channels in scan list one by one. When one channel receives a
matched signal, the transceiver temporarily stays in this channel
untill the signal disappears. Then press Scan key again, transceiver
emits "Du Du" beep, exits scan and switches the working channel to
returned channel which is programmed by users in advance (Please
refer to returned channel in the programming software.).

Frequency Reverse

Under the standby state, pressing the programmed key of
Frequency Reverse, transceiver emits "Du" beep and then comes
into Frequency Reverse state. After that, the current channel RX
frequency will be switched to TX frequency, and the CTCSS or DCS
signal which has been setup will be also switched. Pressing this key
again, the transceiver exits frequency reverse function with "Du Du"
beep.

Talk Around

Under the standby state, pressing the programmed key of Talk
Around, transceiver emits "Du" beep and then the current channel
comes into Talk Around state. Under these conditions, transceiver
will transmit by receiving frequency. Also, the setting code (CTCSS/
DCS) will interchange encoding signaling as decoding signaling.
Pressing this key again, the transceiver exits talk around function
with "DU DU" beep.
