INSTALLATION INSTRUCTIONS
490 SERIES
MICRO LINK™ INFRARED RECEIVERS
These small IR receivers have been designed primarily for mounting in panels, doors, cabinets, etc. for
control of A/V equipment behind closed doors. They may be mounted in walls, ceilings, wall speakers, etc.
- anywhere an inconspicuous appearance is desired. Their high sensitivity allows placement behind
speaker grilles and still receive IR commands up to 20 feet away. If longer range is necessary, a 1/2-inch
hole must be drilled in the grille to allow unobstructed entry of the IR signal. The model versions covered
by these instructions are as follows:
490-00
Standard version, with brass bezel and 7 ft. three-conductor ribbon cable.
490W-00
