OPERATION
If you are unable to activate carrier or no squelch the
radio has been optionally programming for Monitor
Lockout. See your Ritron dealer or contact Ritron
directly to disable this option.
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 radio
sounds a "triple beep". You will only hear broadcasts
that first send your two unique paging tones. If you
are unable to set the radio, you have selected a
channel that is not programmed for 2-tone paging
decode.
To monitor the channel - place the radio in carrier
squelch mode.
Using the "Z" button for squelch - The "Display Series"
base radio "Z" button can be programmed to set the
squelch mode.
Note: The beginning of a call might be missed if the
radio is scanning or has been set for battery saver
mode. If this happens, ask the caller to repeat the
message.
TRANSMIT
Normally, you should monitor the channel before
transmitting 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 improve the listeners reception.
Keep talk times as short and infrequent as possible to
allow others to use the channel.
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 Dis-
play 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 the
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.
To use the "Z" button for Monitor see "How
To Field Program Radio Options" 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 radio can be programmed
using the RITRON PC Programmer for optional alert
tones. See your Ritron dealer or contact Ritron di-
rectly 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 with-
out 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 talk-
ing.
