Other Scanning Features

· Look Back:

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 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 PSCAN button.

NOTE:

Look Back requires that the radio leave the active channel for a fraction of a second (at regular intervals) to check the

priority channel for activity. Depending upon how the radio is programmed (scan 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.

· Scan Channel Delete:

To temporarily delete a channel from the scan list, simply press the monitor button while scanning and

stopped on the channel to be deleted. This will remove that channel from the scan list until the channel is changed or the radio's
power is reset. When power is restored or the scan list channel position is again selected, the original Dealer programmed scan list
will be activated.

· CTCSS/DCS Scanning:

The SM-3000

Enduro

series can be programmed by your Dealer to scan for tone. This will help block out

unwanted calls.

· Normal Scan TX:

Allows a transmission only after a call is received, depending on the programmed scan delay time. After the

scan resumes, and a transmission is made, the radio will sound an alarm (two beeps) , display_h and will not allow a transmission.

· Priority Scan TX:

Allows a transmission after a call is received depending on programmed scan delay time. The transmission

will be made on the channel that the call was received. After the scan resumes, if a transmission is made, the radio will transmit on
the programmed priority channel.

· Priority Only TX:

Allows a transmission on the priority channel when scanning and not stopped on an active channel. It will

always transmit on the priority channel if scanning or stopped on an active channel.

· Receive Only Scan:

This allows only reception. If a transmission is made at any time, the radio will sound an alarm (two beeps),

display r0 and will not allow the transmission.
