To activate 2-tone paging - simultaneously press both
of the volume buttons and hold briefly before
releasing. When 2-tone paging is turned on, the
handheld sounds a "triple beep". You will only hear
broadcasts that first send your two unique paging
tone. If you are unable to set the radio, you have
selected a channel that is not programmed for 2-tone
paging decode.
Using the "Z" button for squelch - The PBS base radio
"Z" button can be programmed to monitor, toggle tone/
carrier squelch, or reset 2-tone paging.
Note:
It is possible that the beginning of a call might
be missed while the radio is in battery saver mode. If
this happens, ask the caller to repeat the message.
TRANSMIT
Normally, you should not transmit until no one is talking
on the channel. This can be determined by monitoring
the channel prior to transmitting.
To transmit - hold down the Push-To-Talk button and
with the radio at least 6 inches away talk into the
microphone. Speak in a normal tone, since talking
louder will not improve the listener’s reception.
Keep talk times as short and infrequent as possible to
allow others to use the channel.
OPERATION
RADIO ALERT TONES
The radio responds to certain instructions by
sounding a beep or series of tones. These tones can
tell you that the radio is working as you expect.
Power On/Self Check “OK”
When it is first turned on, the radio runs a quick
“self test” to confirm basic functions. When
complete the radio will emit the channel beep and
the Channel Display will show the operating
channel. The radio is then ready to use.
Error Tones
However, if the “self test” detects a diagnostic
error, an error tone sounds. The error tone
indicates the radio frequency synthesizer is
malfunctioning. Turn off the radio and try again.
The error tone will also sound if a channel has been
programmed for an invalid frequency. A long, low-
pitched tone means the battery voltage is too low to
operate the radio. If you cannot correct a problem,
consult an authorized Ritron service facility or
Ritron.
Channel Select
When the Channel button is pressed, the radio will
emit a short channel beep, increment the channel,
and the channel display will show the new
operating channel.
Scan Channel
When the Scan channel is selected by pressing the
Channel button, the radio will emit the Scan beep and
begin scanning.
Squelch Mode
When you press and hold both Volume buttons at
the same time, a single beep will sound to indicate
that tone squelch is on. A “double beep” means that
carrier squelch is on. If the channel is programmed
for 2-tone paging, a "triple beep" indicate that the
pager has been reset.
Transmitter Time Out
A low tone followed by a higher-pitched tone
sounds and the transmitter automatically shuts off if
you hold down the PTT button longer than 60
seconds. The radio automatically switches to
receive mode.
Battery Alert Tone
In battery powered installations, as the battery
voltage approaches the minimum required "operating
voltage" the radio will sound a short beep every 20
seconds to alert the user that the battery will soon
need recharge or replacement. Once the battery
voltage drops below the required "operating
voltage" the radio emits a long, low tone and turns
itself off.
OPTIONAL ALERT TONES
The PBS "D-Series" base radio can be programmed
using the RITRON PC Programmer for optional alert
tones. See your Ritron dealer or contact Ritron
directly for programming of these options.
Courtesy Beep
A short tone sounds at the end of each received
transmission to indicate that the channel is clear and
you may transmit.
Busy Channel TX Inhibit
If a user is transmitting on your radio frequency
without your tone, you will not be allowed to
transmit. The radio will beep a series of long, low
tones while the PTT is held down (like a busy
signal).
Transmit Clear To Talk Beep
A short tone sounds after the PTT has been
pressed to indicate that the radio is ready for you to
begin talking.
