QUIET CALL PRIVACY MODULE
G E N E R A L
An optional Quiet Call module may
be plugged into the JBX portable
for locations where an operating
frequency must be shared by
sev-eral licensees. Quiet Call
allows
you
to
broadcasts from other licensees
so you will hear only calls from
other users in your group. With
Quiet Call squelch turned ON, the
radio is quiet unless an incoming
message carries the appropriate
Quiet Call code.
Radios equipped with Quiet Call
transmit a programmable code. To
be heard by other users having
Quiet Call squelch turned ON, a
broadcast must carry the same
code programmed for receiving
unit(s). Note that any radio user
on the channel can listen to a
con-versation coded with Quiet
Call, as long as his radio is not
set for coded squelch.
NOTE:
Quiet Call is RITRON's
tradename for what the
communications industry
calls sub-audible tone,
tone squelch or CTCSS.
To install an optional RTS-5PA Quiet Call module, remove the PC board
assembly from the radio case. Refer to Steps 1-4 below, and to FIG-2, page 6.
1) Remove the battery door by unlocking the door latch and sliding the door away.
2) Take out the battery pack. (Turn the radio over and tap the battery compartment
against the palm of your free hand until the battery pack drops out.)
3) Remove the three T-10 TORX® screws holding the PC board assembly to the radio
case. You can insert a screwdriver through the holes in the case, as shown.
4) Holding the antenna base between your thumb and forefinger, slide the PC board
assembly out of the case top.
Refer to FIG-3 ABOVE for the remaining steps.
5) Turn the PC board assembly over so the speaker is facing up as shown in FIG-3.
6) Align the module as shown in the diagram, with the tape side of the module toward the
radio. NOTE: Do not remove the backing from the tape insulator.
7) Plug the module socket onto the radio’s 9-pin connector. NOTE: Ensure that all nine
pins are fully inserted.
8) Program the RTS-5PA Quiet Call module according to the programming instructions
guide packaged with the module.
