OPERATION
SCAN CHANNEL OPERATION
Channel scanning allows you to listen to broadcasts
on your radio channels. The PBS "D-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. The "Z" button can also be
programmed to initiate scanning.
When receiving a call on a channel being scanned, the
radio will stop scanning to let you hear communica-
tions 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, or when the radio channel is
changed using the Channel Selector button. The 1st
channel in the scan list cannot be blocked.
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.
Priority Scanning (Optional)
The PBS "D-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 OPERATION
To use 2-tone paging the PBS "D-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
handheld sounds three beeps when 2-tone
paging is turned on. The "Z" button may also be
programmed for 2-tone paging reset. If you are
unable to set the radio, you have selected a
channel that is not programmed for 2-tone paging
decode.
When receiving a 2-tone page the radio will emit a
"ring" tone similar to a telephone and the display
will show a "C" to indicate that a call has been
received. You can now proceed with normal two
way communication until 2-tone paging has been
reset. The "ring" tone will sound every time a 2-
tone page is decoded.
To reset 2-tone paging after receiving a call,
simultaneously press both of the volume buttons
and hold briefly before releasing. The handheld
sounds three beeps when 2-tone paging is reset
and the display will show the channel number.
The radio can be optionally programmed to
automatically reset if a call is not answered
within 15 seconds, or the "Z" button can be
programmed for 2-tone paging reset.

page 8.
