USING MULTIPLE SYSTEMS

When multiple systems are used in adjacent rooms, it is important to coordinate which chan- nel is being used in each room to avoid interference.

Follow the channel assignment diagram in Figure 11 to minimize the chances of interference.

To achieve the best performance, DO NOT operate two transmitters on the same channel in the same room and make sure the transmitter and receiver channels match. Consult your dealer or Williams Sound for help if needed.

IN CASE OF DIFFICULTY

IF NO SOUND IS PRODUCED

1.Make sure the batteries are fresh or completely charged and that the “plus” and “minus” terminals are installed correctly in the transmitter.

2.Make sure the transmitter FM switch is ON and the mute switch is OFF.

3.Make sure the microphone is plugged into the T31 Transmitter

4.Make sure the R800’s Power and FM switches are ON.

5.Make sure the transmitter and receiver are set on the same channel.

6.Move the transmitter and receiver closer together. You may be out of range. When using the system indoors, it’s normal for the signal to momentarily disappear in cer- tain locations. This is called a “drop-out.” Moving a few feet will restore the signal.
