PERATION
Channel scanning allows you to listen for broadcasts on all of your radio channels. The RBS-477DMR base radio can scan all
channels programmed into the radio. Be aware that the more channels the radio must scan the longer it takes to check each
channel.
How Scanning Works
Using the P2 BUTTON, select "Scan". The base radio sounds a double beep, the Scan Beep, and the radio then repeatedly checks
each channel in the scan list. "Scanning" appears on the display.
When receiving a call on a channel being scanned, the base radio will stop scanning to let you hear communications on that
channel. After the transmission has ended the base radio will pause before it resumes scanning to allow you time to respond.
When transmitting from the Scan channel, the base radio will go to the last channel on which a signal was received, then transmit.
After you release the PTT the base radio will pause to allow time for a response, and then resume scanning.
Temporary Busy Channel Blocking
If one of the channels in the scan list is very busy you want to temporarily block it out. While the base radio is stopped on the
channel to be blocked, press the P2 BUTTON until "Scan Block" appears on the display and hold it until scanning resumes. The
blocked channel will now be skipped in the scan list.
The blocked channel will be returned to the scan list if "Scan" or "Scan Off" is selected with the P2 BUTTON, or the CHANNEL
SELECTOR button is pressed.
Last Channel Scanned Alert Tone
When changing channels with the CHANNEL SELECTOR button, an alert tone will sound to indicate the last channel that received
a message when the radio was scanning. This will identify the channel on which the last message was received, and allow
uninterrupted transmission on that channel without the constraints of scanning.
Last Channel Received
The base radio can be quickly set to the last channel that received a call while scanning. Press and hold the P2 BUTTON when
"Last Channel" appears on the display. Release the button after the double beep is heard on the speaker.
The radio will stop scanning and go to the channel on which the most recent call was received.
Priority Scanning (Optional)
The base radio can be optionally programmed for priority scanning. Priority Scan allows you to periodically monitor a Priority
Channel, even if the base radio has stopped on another channel. This will prevent missed calls on the primary operating channel
when in scan mode.
With Priority Scan enabled:
•
The radio checks the Priority Channel every two seconds to check for activity. This time is programmable and can be set for 1
- 8 seconds.
•
The base radio can be programmed to transmit only on the Priority Channel when scanning.
•
The base radio can be programmed to sound a Priority Channel Beep whenever the base radio receives on the Priority
Channel when scanning.
