If the M760REM is used as COM 1, the PAR100EX can fail-safe to it, because it is divided internally as
audio panel and COM control. In addition, the M760REM power supply is provided by an independent
circuit breaker and power supply in the PAR100EX. See § 3.2 for operational information.
The PAR100EX must be configured at installation to be used as COM 1 or COM 2, by removing the top
cover, and placing the DIP switches as shown in Figure §2-4.
COM 1

R760REM Antenna connection
The VHF Com radio uses a solder/crimp BNC connector, Amphenol 31-2. Assemble the RF connector as
shown:
Step 1
Place nut, washer and gasket over cable and strip jacket to 5/16” (7.9 mm).
3/32”
Step 2
Comb out braid and fold out. Trim insulation off center conductor to 3/32” (2.4 mm). Tin center
conductor.
Step 3
Pull braid wires forward and taper toward center conductor. Place clamp over braid and push back
against cable jacket.
Step 4
Fold back braid wires as shown, trim to proper length [approximately .1/8” (3.2mm) long] and
form over clamp as shown. Braid wire should not extend beyond step of braid clamp. Solder contact to
center conductor, sliding bushing first (when supplied) over center conductor.
