Base Station
1. For proper system operation, locate the base station module:
•
5 to 6 feet above the floor
•
at least 10 feet from the cashier/drive–thru window
•
At least 3 feet from large metal objects such as refrigerators, ranges, coolers, etc., and other metal or
electrical devices.
!
Important
Do not mount base station under steel countertops, within 3 feet of
coolers/refrigerators/ranges or in areas where it will be obscured by steel
doors, walls, etc. as this will cause operational problems.
2. Mount the base station using the included screws and anchors. (See Figure 3.)
Figure 3. Base Station Mounting Holes
3. Install conduit and cable clamps as necessary.
4. Feed the cables for speaker, microphone, vehicle detect and monitor speaker (if used) through the conduit
down to the interconnect module or base station. (See Figure 1.)
5. Feed the transformer cable from the outlet to the base station. (See Figure 1.)
Keep the transformer cable at least 6 inches from the left half of the base station. This half contains sensitive
radio components which will be affected if the cable is too close.
