level is fixed and setting this control has no affect. Conventional features
are described starting on page 33.
Monitoring Conventional Channels Before Transmitting
Regulations require that the channel be monitored before transmit-
ting to make sure that it is not being used by someone else. If you were to
transmit when someone else is talking, you would probably disrupt their
conversation. In the LTR mode, monitoring is performed automatically.
However, in the conventional mode, it must be performed automatically
or manually as follows.
Automatic Channel Monitoring
If the selected channel is programmed for the Transmit Disable On
Busy feature, monitoring is performed automatically. Refer to page 33 for
more information on this feature.
Manual Channel Monitoring
If the preceding feature is not used, monitoring must be performed
manually using the monitor mode. This mode is enabled by taking the
microphone off-hook (unless off-hook detection has been disabled by
programming). It may also be enabled by the AUX1 or AUX2 switch if
either is programmed for the monitor function. The monitor mode tempo-
rarily disables Call Guard squelch (see page 34) and scanning so that all
messages on the channel are heard. Refer to the monitor mode description
on page 33 for more information.
