3 ) R o t a t e t h e [ S Q U E L C H ] c o n t r o l m a x i m u m
counterclockwise and confirm that the [BUSY] in-
dicator lights up in green.
1) That the [COR SIMULATE] switch is OFF.
2) That the [VOLUME] control is rotated maximum

3-2 OPERATION
For open repeaters:
1) Turn the [POWER] switch ON. The [POWER] in-
dicator lights up in green.
l If the [POWER] indicator lights up in red, AC power
is not applied to the repeater. Make sure the AC
cable is correctly connected.
l When using only DC power, turn the [POWER]
switch ON then push the [DC RESET] switch to
apply power. Confirm that the [POWER] indicator
lights up in red.
2) Set repeater mode for either a private or
repeater.
For private repeaters:
Push the [CTCSS] switch ON. The [CTCSS] in-
dicator lights up and the repeater transmits only
received signals with specified subaudible tones su-
perimposed on them.
Push the [CTCSS] switch to turn OFF the tone
squelch function if the [CTCSS] indicator lights up.
The repeater transmits all receive signals if the
[CTCSS] indicator does not light up.
3) That the [SQUELCH] control is rotated maximum
clockwise.
4) That the supplied HM-4 microphone is connected to
the mic connector.
5) Rotate the [SQUELCH] control clockwise until the
[BUSY] indicator goes OFF and noise from the
speaker disappears.
l The level of this control determines the level of the
input signals to be repeated. Adjust [SQUELCH]
as required to repeat only strong signals.
