When Carrier or Tone Squelch is selected by the user, all
channels will operate in that mode. The JBS / PBS "D-Series"
base station will operate in tone squelch mode when it is first
turned on.
QC AND DQC TONE CODES
Tone codes filter out static, noise and reduce unwanted "chatter"
on radio channels. When you operate on a frequency with a tone
code, you screen out most interference. This allows you to
communicate with less interference and to hear only those users
in your radio group.
IMPORTANT! All radios in the talk group must operate on the
same frequency and tone code.
SQUELCH MODES
To activate Tone Squelch or Carrier Squelch and to Monitor the
channel - you may either simultaneously press both the On /
Volume Up and Volume Down / Off volume buttons and hold
briefly before releasing, or if the "Z" button is set for the monitor
function (see page 15), then press the "Z" button and release. To
advance to the next squelch mode simultaneously press both
volume buttons, or press the "Z" button.
1. If the base station emits a SINGLE beep, then Tone Squelch
is turned ON and you will only hear radio transmissions on
that channel with the same QC or DQC tone codes as your
base station.
2. If the base station emits a DOUBLE beep, then you are in
Carrier Squelch and you can Monitor all broadcasts on the
channel. To exit Carrier Squelch press and hold both
volume buttons until you hear the SINGLE beep.

OPERATION
3. If the base station emits a TRIPLE beep, then you are in 2-
TONE DECODE. You will only hear broadcasts that first 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.
To use the "Z" button for Monitor see 'How to Field Program
Radio Feature Codes" on page 15.
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 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.
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.
