3. If the base station emits a TRIPLE beep, then you
are in 2-TONE DECODE. You will only hear
broadcasts that rst send your two unique paging
tones. If you are unable to set the base station, you
have selected a channel that is not programmed for
2-tone Decode.
If you are unable to activate Carrier Squelch - the base
station has been programmed for Monitor Lockout. See
your Ritron dealer or contact Ritron directly to disable
this option.
Using the "Z" button for Monitor - the JBS/PBS
"D-Series" base station "Z" button can be programmed
for Monitor mode.
Note: It is possible that the beginning of a call
might be missed while the base station is in
battery saver mode. If this happens, ask
the caller to repeat the message.
TRANSMIT
Normally, you should monitor the channel before trans-
mitting and talk only when the channel is clear.
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 im-
prove the listener’s reception.
Keep talk times as short and infrequent as possible to
allow others to use the channel.
RADIO ALERT TONES
The base station 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 rst turned on, the base station runs a quick
“self test” to conrm basic functions. When complete the
base station will emit the Channel Beep and the Channel
Display will show the operating channel. The base station
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 base
station 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 base station. If you cannot correct the
problem, consult an authorized Ritron service center or
Ritron directly.
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
Code, a TRIPLE beep indicates that the base station is
in 2-Tone Decode mode.
To use the "Z" button for Monitor see "How
To Field Program Radio Feature Codes" on
page 12.
FIG-3: TRANSMIT/BUSY LAMP
A Transmit / Busy Lamp in the lower
right corner of the Channel Display
lights whenever the transmitter is
activated and blinks when the channel
is busy.
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.
Battery Alert Tone
In battery powered installations:
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 "Display Series" base station 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 trans-
mission 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 base
station 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 base station is ready for you to begin
talking.
