Other Scanning Features
·Look Back: Any channel, when not in the scan mode, can be programmed to "look back" at the "Priority"
channel. (Remove) This feature is ideal for those who do not need scan as defined above, but want to
make sure that they never miss a call on the "Priority" channel if another channel has been selected. Once a
"look back" (Remove) channel other than the priority channel has been selected, the radio will periodically
"look back" at the Priority" channel. If activity is detected on the "Priority" channel, the radio will move to
that channel for as long as it remains active. To enter look back mode, press and hold the scan button, first

NOTE: Look Back requires that the radio leave the active channel for a fraction of a second (at regular

speed, etc.) this may or may not be noticeable as "breaks" on the active channel for that same fraction of a
second. A transmission will be made on the selected channel at all times.
