Busy Lockout
To help prevent accidental transmissions over the top of
other users, the TX3500S incorporates a Busy Lockout
feature.
The Busy Lockout function detects when others outside
your CTCSS/DCS group are transmitting on the channel
and prevents your radio from transmitting over them. If the
channel is busy and you press the PTT the radio will emit a
warning beep and the
icon won’t be displayed. When
you release the PTT, look for the icon on the display
as an indicator that the channel is in use. If the channel is
busy, simply wait until the channel is clear and press the PTT
again.
NOTE: You can also press the Monitor key to open the
squelch and listen for signals on the channel before
transmitting (see Monitor Function directly below).
To enable Busy Lockout
1. Press and hold the Channel knob to enter the MENU.
‘br’ will be displayed.
2. Press the Channel knob repeatedly until ‘bL’ (Busy
Lockout) is displayed.
3. Rotate the Channel knob one click. The current setting
is displayed.
4. Rotate the Channel knob to the right to enable busy
lockout. ‘on’ will be displayed.
5. Rotate the Channel knob to the left to disable busy
lockout. ‘oF’ will be displayed
When finished, press and hold the Channel knob to return
to normal operation.
Monitor Function
If the busy icon shows that the channel is busy, but
you cannot hear any sound, the signal is probably using a
different CTCSS/DCS tone to yours.
If you wish to listen to the signal to confirm that someone
else is using the channel, press and hold the Volume knob.
This activates the ‘monitor’ function which temporarily
disables the CTCSS/DCS system in your radio to allow the
signal to be heard in the speaker. When the Volume knob
is released the channel will become quiet again.
NOTE: While the Volume knob is pressed, the icon
flashes.
RECEIVING (RX) ONLY CHANNELS
The radio includes support for up to 19 RX-only dealer
programmable frequencies in the range of 403-520MHz.
RX-only channels, when installed, can be found above
