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. You can then press the Channel Selector
button to return to the scan channel.
Using The "Z" Button For Scan
The special feature "Z" button can be programmed to
initiate scanning. The UHF PBS-446D and JBS-446D
base stations are programmed for "Z" button Scan
channel operation from the factory.
To select the Scan Channel, press the "Z" button. The
radio sounds the Scan Beep, and scanning operation is
initiated. The Scan channel will not be accessible with
the Channel Selector button when the base station is
programmed for "Z" button Scan channel operation.
To return to normal channel operation, press the
Channel Selector button and the base station will return
to channel 1.
To temporarily block a busy channel while scanning,
press the "Z" button while the base station is stopped
on the channel to be blocked and hold it until scanning
resumes. The blocked channel will now be skipped in the
scan list.
Priority Scanning (Optional)
The "Display Series" base station can be optionally
programmed for priority scanning. Priority Scan allows
you to periodically monitor a Priority Channel, even if the
base station has stopped on another channel. This will
prevent missed calls on the primary operating channel
when in scan mode.

With Priority Scan enabled:
• The rst channel in the scan list is the Priority
Channel.
• 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 station can be programmed to transmit only
on the Priority Channel when scanning.
• The base station can be programmed to sound a
Priority Channel Beep whenever the base station
receives on the Priority Channel when scanning.
See your
Ritron dealer or contact Ritron directly for PC
programming of this option.
2-TONE DECODE OPERATION
To use 2-Tone Decode the "Display Series" base
station must be PC programmed for this option,
the radio does not operate with 2-Tone decoding as
it is received from the factory. See your Ritron dealer
or contact Ritron directly for PC programming of this
option. This feature allows the base station to act as a
monitor receiver.
To activate 2-Tone Decode you must rst select a radio
channel that has been PC programmed for 2-Tone
Decode. The factory default setting will automatically
activate 2-Tone Decode any time the 2-Tone Decode
channel is selected. If not, simultaneously press both
of the volume buttons and hold briey before releasing.
The radio sounds three beeps when 2-Tone Decode is
turned on.
If you are unable to set the base station, you have
selected a channel that is not programmed for 2-Tone
Decode.
To turn Channel Scan On/Off see "How
To Field Program Radio Feature Codes"
on page 12.
CHANNEL SCAN OPERATION
Channel scanning allows you to listen to broadcasts on
your radio channels. The JBS/PBS "Display-Series" base
station will scan all channels programmed into the radio
except the NOAA Weather Channel.
How Scanning Works
Using the Channel Selector button, select the Scan
channel. The base station sounds the Scan Beep, and
then repeatedly checks each channel in the scan list.
The channel display will show the channel numbers as
they are scanned.
When receiving a call on a channel being scanned,
the base station will stop scanning to let you hear
communications on that channel. After the transmission
has ended the base station will pause before it resumes
scanning to allow you time to respond.
When transmitting from the Scan channel, the base
station will go to the last channel on which a signal was
received, then transmit. After you release the PTT the
base station 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 so busy that
you want to temporarily block it out, press the Channel
Selector button while the base station is stopped on the
channel to be blocked 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
the base station is turned off and then back on again, or
when the radio channel is changed using the Channel
Selector button. The rst channel in the scan list cannot
be blocked.
