Scan Modes
Scanning is a Dealer programmable feature that allows you to monitor a number of channels or channels
within a Group. Your Dealer will help you define a scanning mode and your channel "scan list" .
Normal Channel Scan
Once the scan list has been established you can initiate scan by press and release of scan button, first
button located beneath the PTT button. The top panel LED can be programmed to flash green as the radio
is scanning.
If a conversation is detected on any of the channels in the scan list, the radio will stop on that channel
and you will be able tohear the conversation. If programmed for normal scan TX you will be able to
transmit on that active channel during the pro-grammable scan delay time. The scan delay time is the
amount of time the radio will stay on that channel once activity has ceased (Dealer programmable, 4-7
seconds is typical). The radio will resume scanning once the scan delay time has expired. Scanning will
continue until the channel is changed.
Priority Channel Scan
A single channel may be programmed as the "Priority" channel. The radio will constantly monitor this
channel while scanning and when the radio has stopped on an active channel. If a call is detected on the
"Priority" channel, the radio will automatically move to, and remain on, the "Priority" channel for as long
as the priority conversation takes place. "Priority" channel activity takes precedence over all other
conversations. To activate Priority scan press and release the scan button, first button beneath the PTT
button. When priority scan has been activated display will show PS to indicate priority scan has been
activated. ( Remove)
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 button located beneath the PTT button. PS will be shown in the display and the LED will flash
green.
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/DTMF Scanning: The SP-6402 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 can also be programmed to ( Remove) 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.
