10.1. GENERAL.
The SINCGARS radio may be controlled by the Handheld Remote Control Radio Device (HRCRD). The use of the
HRCRD requires either a connection to the VAA (control monitor connector) or use of a special battery box
(CY-8523C/PRC). Operating instruction for the HRCRD are found in TM 11 5820 890 10.
10.2.
HANDHELD REMOTE CONTROL RADIO DEVICE (HRCRD).
a.
Maintenance Concept. The maintenance concept for the HRCRD is for the unit level maintainer to
determine if the HRCRD is defective and if defective replace and discard the defective unit. The HRCRD
is not repairable. Unit SOP should indicate how replacement HRCRDs are to be provided to subordinate
units.
b.
Unit Level Maintenance Tasks. The unit level maintainer may determine if the HRCRD is defective by
obtaining a replacement HRCRD and replacing the original. If the replacement unit operates as it
should, the original unit is defective. If the replacement unit does not operate the problem may be in the
remote control battery pack (Manpack configuration), VAA (Vehicular configuration), or in the RT. The
remote control battery pack may be isolated through remove and replace procedures. Refer to
TM 11 5820 890 20 1 for RT and VAA troubleshooting procedures.
