Ge X Ees; Separating Rx Audio Signals; Microprocessor Squelch Control - Kenwood TM-732A Instruction Manual

3. MUTE
When a signal is received on the transmit band, the
receiver volume for the other band is reduced
automatically to make the incoming signal easy to hear.
This function is called muting. To select this function,
press the MUTE/ABC key. TheMUTE indicator will
appear in the display. When a signal is received on the
transmit band (the PTT indicator lights), and the
volume for the other band is reduced to 1/10.
To cancel
Press the MUTE/ABC key again.
4. Separating RX Audio Signals
Receive audio signals can be separated by connecting
an external speaker (option).
When a single external speaker is connected to the
SP1 jack.
Normally the audio is distributed as shown in
the diagram below. This combination can be
reversed. Press the F key for longer than one
second, then press the C.SEL key while the F
indicator is flashing.
32
When an external speaker is connected only to SP2,
the internal speaker is turned off, and the receive audio
for both bands is output from SP2. The SP-50B or SP-
41 are recommended for those connections.
5. Microprocessor Squelch Control
Squelch operation may be controlled by the
microprocessor to automatically select the threshold
point without operating the SQL control. When this
function is selected, you do not need to adjust the SQL
control. This function can be set for each band.
1. Turn the POWER switch off.
2. Hold down the MHz key, then press the POWER
switch.
3. Press the BAND SEL key for the band in which the
function is to be set.
4. Hold down the F key, then press the LOW key.
To cancel squelch microprocessor control, switch the
power off and perform step 2.
