The Quick Assist II offers selectable “compressed” or
“non-compressed” transmitted audio. Some manufactur-
ers call this feature “X-pand” or “Companding”. The Quick
Assist II must match your existing 2-way radios for
optimal quality. To determine if your existing 2-way radios
are using “companding” you can call the manufacturer of
the radio, refer to your owners manual or call Ritron for
help.
If you are unable to determine if your 2-way radios are
using the “companding” feature, we suggest you take the
following logical steps:
1. Leave the jumper in the factory default setting NON-
COMP .
2. Activate the transmitter of the Quick Talk or Quick
Assist (I or II) and listen to the message from your
portable radio. If the received audio is acceptable, skip
the rest of this section, if it’s not acceptable continue to
step #3.
3. Change the jumper setting to the COMP position and
activate the Quick Talk or Quick Assist (I or II)
transmitter again, and listen to the voice message.
Place the jumper in the setting that produces the best
“received” audio message in the radio you will be using.

You may change the Transmitter Bandwidth and Compressed/Non-Compressed Audio jumper settings without
re-recording your custom voice message.
The Quick Assist II offers selectable bandwidth “Wide” or
“Narrow”. The Quick Assist II must match the bandwidth
setting of your existing 2-way radios for optimal quality.
As a general rule, if the operating frequency of your radios
has less than three numbers to the right of the decimal
point your frequency is “Wide” band.
Example: frequency 154.570 MHz or 462.625 MHz
If more than three numbers to the right of the decimal
point, your frequency is most likely “Narrow” band.
Example: frequency 467.7625 MHz or 467.8125 MHz
To determine your operating frequency and bandwidth
check your 2-way radio, yourowners manual, or call Ritron
for help. You can also look for your frequency and corre-
sponding bandwidth/channel spacing in the table listed on
page 7 of this manual.
If you are unable to determine if your 2-way radios are
Narrow or Wide band, we suggest you take the following
logical steps:
1. Leave the radio in the Wide band factory default mode.
2. If the received audio is acceptable, skip the rest of this
section, if it’s not acceptable continue to step #3.
3. Change the jumper setting to Narrow and listen to the
voice message.
Place the jumper in the setting that produces the best
“received” audio message in the radio you will be using.
FIG—3. J102 SETTING FOR NARROW OR
WIDE-BAND OPERATION
Narrow-Band Wide-Band
Selecting “Wide” (25kHz) or “Narrow” (12.5kHz) Bandwidth/Channel Spacing
Wide: (Refer to FIG-3)
To set your Quick Assist II into wideband position, place
the Transmitter Bandwidth Select Jumper so that both
pins of the 2 pin connector are covered by the jumper.
Narrow: (Refer to FIG-3)
To set your Quick Assist II into narrowband position, place
the Transmitter Bandwidth Select Jumper so that only 1
pin of the 2 pin connector is covered by the jumper.
