General
Although the HRCRD is intended for use with manpack radios,
it can be employed with vehicular configurations that do not include a control-monitor
by connecting one end of the "Y" cable to J9 connector (C-M) at the rear of
the vehicular amplifier adapter (VAA).
Access to the RT Front Panel is required whenever it is
necessary to change the FCTN switch, to adjust audio volume at the RT, and to
change the light level in the RT display.
The cable of the HRCRD forms a "Y" with one end connected
to the RT AUD/DATA or AUD/FILL port. The other end is connected to the 6-pin
connector on Battery Box, CY-8523C (for RT 1523C/D) or the AUX connector of
the RT-1523E.
The HRCRD back light can be turned on with one press of
the round light button. A second press of the light button turns the back light
off.
The level of audio volume at the HRCRD can be adjusted by
use of the thumb wheel on the side of the HRCRD.
The HRCRD enables the manpack operator to control the following
functions of the radio using the HRCRD: Channel, RF Power, Mode and COMSEC.
The RT FCTN switch must be set to REM for HRCRD to be functional.
The new Handheld Remote Control Radio Device (HRCRD), C-12493/U,
is used with manpack radio AN/PRC-119A/D/F and the dismounted kits of vehicular
radio configuration AN/VRC-88A/D/F and AN/VRC-91A/D/F.
