OPERATION
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. PBS-446D and JBS-446D UHF base
radios 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 radio is
programmed for "Z" button Scan channel operation.
To return to normal channel operation, press the
Channel Selector button and the radio will return to
channel 1.
To temporarily block a busy channel while scanning,
press the "Z" button while the radio 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 radio can be optionally
programmed for priority scanning. Priority Scan allows
you to periodically monitor a Priority Channel, even if
the 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 first 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 radio can be programmed to transmit only on
the Priority Channel when scanning.
 The radio can be programmed to sound a Priority
Channel Beep whenever the radio receives on the
Priority Channel when scanning.
See your Ritron dealer or contact Ritron directly for PC
programming of this option.
2-TONE PAGING DECODE OPERATION
To use 2-tone paging decode the "Display
Series" base radio 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.
To activate 2-tone paging you must first select a radio
channel that has been PC programmed for 2-tone
paging decode. The radio is normally programmed to
automatically activate 2-tone decode any time the
paging channel is selected. If not, simultaneously
press both of the volume buttons and hold briefly
before releasing. The radio sounds three beeps when
2-tone paging is turned on.
If you are unable to set the radio, you have selected a
channel that is not programmed for 2-tone paging
decode.
To turn Channel Scan on / off see "How To
Field Program Radio Options" on page 12.
CHANNEL SCAN OPERATION
Channel scanning allows you to listen to broadcasts
on your radio channels. The "Display-Series" base
radio 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 radio 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
radio will stop scanning to let you hear
communications on that channel. After the
transmission has ended the radio will pause before it
resumes scanning to allow you time to respond.
When transmitting from the Scan channel, the radio
will go to the last channel on which a signal was
received, then transmit. After you release the PTT the
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 so busy that
you want to temporarily block it out, press the
Channel Selector button while the radio 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 radio is turned off and then back on again, or
when the radio channel is changed using the Channel
Selector button. The 1st channel in the scan list cannot
be blocked.
