Lectrosonics R172 - Manual (Page 6)

OPERATING INSTRUCTIONS
SET UP AND OPERATION SEQUENCE
1) CONNECT POWER CORD -- Plug the connector of the CH-12 adapter included with the receiver into the jack
labeled "12 VDC INPUT." Insert the plug fully into the jack.
2) ATTACH THE ANTENNAS - Two antennas are provided with the receiver. If the system is not rack mounted,
the unit will have a telescoping whip antenna and a coaxial dipole antenna (this antenna looks like a piece of cable
with a small loop in one end and a BNC connector on the other). If it has been mounted into an RMP3 rack kit, then
it will have two coaxial dipole antennas.
If the system will be installed with one antenna - Attach the single antenna to the BNC connector
marked SNGL on the rear of the receiver. Set the ANTENNA MODE switch to SNGL
If the antenna is the telescoping whip, extend the antenna to its full length.
The coaxial dipole antenna should be uncoiled and led away from the receiver. The loop on the end is
provided as a convenient attachment point. The cable should be hung on a wall or suspended so the last
3.5 ft are straight and not close to any metal surfaces such as file cabinets, metals walls, or metal studs.
Wood stud drywall construction will present no problems and the antenna may be hung against the wall.
Some contractors have actually run the antenna up inside hollow walls. Be sure to test the system before
committing the system to a particular antenna placement.
