Enabling and Disabling Transmit Inhibition
Enabling Transmit Inhibition
Perform one of the following actions:
•
From the home screen, scroll
left
or
right
to
TxIn
. Press the
Menu Select
button below
TxIn
.
•
Turn off the ignition through Ignition Sense Line.
The display shows
Tx inhibit on
. You hear a sequence of short, low-high tones to indicate that transmission
is inhibited.
Pressing
PTT
triggers the radio sounds a constant short, low-pitched tone (reject tone).
Note:
The status of the Transmit Inhibit does not change after the radio powers up. The softkey
TxIn
is
created to ease the user of inhibition transmission besides relying solely on Ignition Sense Line. Only if the
Ignition Sense Line is on, the softkey
TxIn
works. If the Ignition Sense Line is on, you can always turn on or
off the Transmit Inhibition using the softkey
TxIn
; but when the Ignition Sense Line is off, function of softkey
TxIn
is suspended, and the Transmit Inhibition function is always off.
If PTT TX Inhibit is enabled, when using multi-control head with one active configuration, with the PTT pressed
on the active control head, any press on the programmable button of the other control head which meant for
that control head to be active control head causes an unstoppable long low-pitched tone (Talk Prohibit Tone).
The display shows Tx inhibit. This behavior can be stopped by pressing PTT button again on the active control
head.
