CONTROL & OPERATION
IMPORTANT: CHARGE THE BATTERY PACK before using the radio for the first time. Refer to Batteries, pages 11 and 12.
page 2
1 ANTENNA
The flexible antenna radiates and receives radio signals.
Screw the antenna base all the way into the threaded
bushing on top of the radio.
NOTE: Use only the type of antenna furnished with
the radio. VHF and UHF antennas are not
interchangeable.
2 ON/ VOLUME UP
To switch the unit On, press the On/ Volume Up button;
the speaker will emit a turn on beep. If the radio turns
on to the Scan Channel it will emit the Resume Scan
Beep. Once the radio is On, press this button to
increase volume.
3 VOLUME DOWN / OFF
Press the Volume Down/ Off button to decrease
volume. To switch Off the unit, press and hold this
button until the speaker emits a double beep.
4 PUSH-TO-TALK SWITCH (PTT)
Press and hold the PTT when transmitting; release it to
receive.
5 CHANNEL SELECTOR
Press the button and the radio will emit the channel
beep, advance the channel, and the channel display will
show the new operating channel. When the Scan
Channel is selected the radio will emit the Resume Scan
Beep and the radio will begin scanning.
6 BATTERY ACCESS DOOR
(CASE BOTTOM)
The battery access door may be removed to access
the battery pack. Refer to Battery Access & Installation,
FIG-8, page 11.
7 JACK COVER
This rubber cover seals out dust and moisture, etc.
Snap the cover into the audio accessory jack and
charge jack openings when the jacks are not in use.
8 AUDIO ACCESSORY JACK
The audio accessory jack is used to plug in earphone
options, and, in conjunction with the charge jack, to
connect an optional remote speaker/ microphone or a
single- or dual-ear headset. This jack is also used for
PC programming.
9 CHARGE JACK
The battery pack may be charged through this jack
using the RITRON charger cube. Refer to Accessories,
page ii, for additional charging options.
10 CHANNEL DISPLAY
The channel display will indicate the current operating
channel. When the Scan Channel is selected the
display will rapidly flash the channels being scanned,
and will stop when a channel is received.
11 SPEAKER
The speaker, located behind the front grille, allows you
to hear calls on your channel.
12 MICROPHONE

OPERATION
page 3
ON-OFF / VOLUME ADJUST
To turn on the radio - press the On/Volume Up button.
The radio will emit the Channel beep. If the radio turns on
to the Scan Channel it will emit the Scan Beep. The radio
will turn on to the channel that was selected when it
was last turned off, or can be programmed to always
turn on to channel 1.
To adjust the volume - press the volume up or the volume
down button until you reach the desired level. You
should hear noise or any broadcasts on the channel.
To turn off the radio - press and hold the Off/Volume
Down button until a two tone "turn-off" beep is heard.
For instant turn-off, press the PTT button while holding
the Off/Volume Down button.
SELECTING CHANNELS
To change channels - press and release the Channel
Selector button. The radio will emit a short Channel beep,
increment the channel, and the Channel Display will
show the new operating channel. If the highest channel
number is selected and you press the Channel Selector
button, the radio resets to channel 1 and the Channel
beep is heard on the speaker.
If the Scan Channel is selected - the radio will emit the
Scan Beep and the Channel Display will rapidly flash the
channel numbers as they are scanned. If a signal is
received the channel display will indicate the channel
number, and when the received signal is removed the
radio will wait briefly, sound the Scan Beep, then
scanning will resume as normal.
If the Weather Channel is selected - on a VHF radio the
Channel beep will be heard and the display will light a
single segment that indicates which of the seven NOAA
frequencies is monitored. See the "NOAA Weather
Radio" section on page 8 for details.
RECEIVING CALLS
To hear calls from other users - adjust the volume as
desired. The radio can receive broadcasts while the
Push-To-Talk button is not being pressed. Whether or
not you hear these broadcasts depends upon the
squelch settings.
There are four squelch modes that can be used in the
SST "D-Series" portable.
Carrier squelch lets you hear all broadcasts on
your channel strong enough for the radio to detect,
and silences noise.
Tone squelch uses one of the QC or DQC tone
squelch formats available on the SST. This allows
you to screen out on-channel broadcasts that do
not carry the correct code programmed for the
radio.
No squelch disables all squelch operation and
allows you to hear even the weakest broadcasts
on your channel.
2-tone paging can be used in conjunction with
either carrier or tone squelch to block out all calls
except those sent specifically to your radio. When
the unique 2-tone sequence programmed into the
radio is decoded, the radio will emit a series of ring
tones similar to a telephone.
If Carrier or Tone Squelch has been selected by the
user, all channels will operate in that mode. The SST
"D-Series" radio will operate in tone squelch mode
when it is 1st turned on.
To monitor the channel - press one of the volume
control buttons. When you press the volume up or the
volume down button, squelch turns off and all radio
traffic on the channel (or noise) sounds in the
speaker.
To activate carrier squelch - simultaneously press
both of the volume buttons and hold briefly before
releasing. When carrier squelch is on, the radio emits
a double beep. The radio will now let you hear all
broadcasts on your channel.
To activate tone squelch - simultaneously press both
of the volume buttons and hold briefly before
releasing. When tone squelch is turned on, the
handheld sounds one beep. You will only hear
broadcasts that carry the same QC or DQC code
programmed into your radio.
To activate no squelch - simultaneously press both of
the volume buttons and continue to hold them down.
About 3 seconds after the beep (or double beep), the
radio will start beeping repeatedly. This means that
squelch is turned off. Release the buttons. To restore
squelch, press and hold both of the volume buttons
until the radio sounds a beep or double beep.
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.
QC AND DQC TONE CODES
(Interference Eliminator 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.
