Talk–Back Scan
In addition to changing pre-programmed (channel-slaved) scan lists and the
second priority channel, the radio service software (RSS) also provides the
capability for "talk-back" scan. If this feature is enabled, the radio will remain on
the active channel when the microphone is taken off-hook instead of returning to
the selected (home) channel. This allows the user to respond or "talk-back," to a
transmission received on a scanned channel.
Nuisance–Channel Delete Feature
Each of the MaxTrac 300 16-channel and 32-channel radio scan types have the
nuisance-channel delete feature. If a channel in a scan sequence is at times in
heavy use by another operator causing the radio to be continually monitoring that
channel, you may wish to temporarily eliminate that channel from the scan list
without reprogramming the radio. When receiving a transmission on that channel,
simply hold down the Select button for 2 seconds and the nuisance channel will
be temporarily deleted until that scan mode is changed or exited. Priority channels
and the home channel cannot be deleted.
Scan Rates
The radio service software (RSS) also provides the ability to change the frequency
with which a priority channel is checked. When the Channel Scan is stopped on a
non-priority channel, it periodically "checks" the priority channel for activity. The
rate at which this occurs is the priority sample rate. There are two rates
available: fast is 0.5 seconds and slow is 1.5 seconds. Although the fast rate
provides more assurance that a message won't be missed, it is, in effect,
interrupting the current reception more often. Therefore, the radio is normally
programmed for slow.
