Place the receiver where there is a clear line of sight to the area where the transmitter will be used. 2. Attach either the supplied 1/4-wave antennas or two remotely mounted antennas to the antenna connectors on the rear panel of the FMR-10. Be sure and tighten the connectors securely. If the supplied o 1/4-wave antennas are used, they must be oriented at a 90 angle as shown in Figure 2. Unlike o

CAUTION: Please make sure that the AC adapter is the cor- rect voltage for your local requirements. 4. ClearScan™: The FMR-10 Wireless system features ClearScan™. ClearScan™ automates the process of finding a clear channel to use in setup of your FMR-10 Wireless system. To use ClearScan™, depress and hold down the set button for 3 sec- onds. When the channel display begins flashing release the set button. The receiver is now searching for a clear frequency by measuring the RF energy present on e

3.1.2 3.1.2 Antenna Antenna Placement Placement For any wireless system to perform correctly, strong RF signals are mandatory. To maximize signal strength, good antenna placement must be utilized. Although some situations prohibit perfect antenna placement, here are some guidelines: 1. The antennas should be placed in a location with a clear signal path to the transmitter. Walls, ceilings, metal objects, equipment racks, etc. are all signal barriers that will reduce range and perfor- mance. Gene

If antennas are remote-mounted, separating them 6 feet (1.8m) or more and keeping them at least 2 feet (.6m) from other barriers will improve performance (see Figure 8). If you are remote mounting the antennas and require strong signal over a large area, consider using highly directional antennas such as a log-periodic. The ALP-450 available from Telex is tuned for frequencies from 450-900 MHz and can provide an additional 5 dB of gain. 3. If you remote-mount the antennas, attention should be pa

Battery Battery Recommendations Recommendations Fresh 9-volt alkaline batteries from a quality manufacturer will yield the best performance from your FMR-10 transmitters. Rechargeable 8.4-volt Ni-cad batteries can be used, but will yield much shorter op- erational time. When the transmitter switch is turned on, the red battery light will flash once if the battery is good. If the light does not flash or stays lit continuously, the battery is weak or dead. If the light comes on during use, the bat
