Radio Alert Tones; Optional Alert Tones - Ritron Display JBS-146D Owner's Manual

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 first turned on, the base station runs a quick "self test"
to confirm 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.
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.

OPERATION
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 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 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.
