‘ ‘ Monitor audible function
The monitor function allows you to open the transceiver’s squelch
manually to check whether a channel is busy or not. The trans-
ceiver has 2 conditions for receive standby:
• Audible condition:
This condition mutes audio ONLY when
no carrier is present. You can receive (or
monitor) any signals on a channel.
• Push and hold the [MONI] switch to can-
cel the CTCSS or DTCS tone squelch
function.
Any audio mute functions are cancelled
while pushing the [MONI] switch.
• Inaudible condition: This condition
mutes ALL signals except those directed
to you. Therefore you should check a
channel’s condition (busy or not) with the
monitor function before transmitting.
• Push the [MONI] switch momentarily to
select the inaudible condition.
‘ ‘ Time-Out Timer
The transceiver has time-out timer function. This function prevents
continuous, extend transmissions. This timer automatically turns a
transmission OFF 3 min. after it starts.
A warning beep emits 10 sec. before the limit is reached.
The end beep emits 5 times to announce the end of the transmis-
sion.
All signals are
received
Only signals con-
taining the proper
tone are received
