Advance Operations; Squelch Off; Monitor; Hi/Low Power Switch - RTS DV-3400 Instruction Manual

ADVANCE OPERATIONS

[PF1] and [PF2] are programmable, which can realize certain
functions as bellow via programming software.
NOTE:
To start the function programmed on the [PF1]-1s or [PF2]-
1s, users need to press and hold [PF1] or [PF2] untill the
transceiver voice "DU" and then release.
Repeat the above operation to turn off the programmed
function.

Squelch off

Under the standby state, pressing the programmed key of Squelch
off [PF1] / [PF2], the squelch circuit is not mute and at present you
can hear the background noise. Press this key again, the squelch
circuit becomes mute. By using this function you can monitor the
weaker signal which is hard to receive. Meanwhile, LCD will display
current signal intensity.

Monitor

Pressing the programmed key of Monitor [PF1] / [PF2], the
transceiver emits "Du" beep and then comes into the monitor state.
Under these conditions, transceiver will ignore CTCSS / DCS
decode and monitor signal of the other party as long as receiving
the matched carrier wave. Press this key again, transceiver emits
"Du Du" beep and exits the monitor state.

Hi/Low Power Switch

Pressing the programmed key of Monitor [PF1] / [PF2], the
transceiver emits "Du" beep and then announces current power
state. If "HI" is selected, current channel transmits
at high power. If "Low" is selected, current channel
transmits at low power.
