Hints for Using the System:
Normal operating distance between the Transmitter and Receiver is about 100 feet (30m). The operating range will vary in different buildings and surroundings. In some locations, the signal may momentarily disappear. This is called a
Keep the Transmitter and Receiver units at least two feet apart. If the Transmitter gets too close to a receiver, it can overload the Receiver, causing noisy reception or blocking of the signal.
Do not coil or bunch up the microphone or headphone cords. The cords act as antennas. Let them hang at full length for the best results.
Do not use more than one Transmitter on the same channel (frequency) at the same time unless they are physically separated by 50 to 100 feet (15 - 30 m). Operating more than one Transmitter on the same channel at the same time in the same place will result in interference.
Using Multiple Systems for Multiple Groups:
For multiple tour groups within the same facility, multiple Tour Guide Systems may be operated on the same channel at the same time by maintaining physical separation of 50 - 100 feet between groups. The physical separation of groups takes advantage of the FM capture effect which causes receivers to lock onto the closest transmitter.
Up to four systems can be operated simultaneously in the same facility if they all operate on differ- ent channels. Channels A,C,E, and G may be used simultaneously.

If the sound becomes weak or distorted, replace the battery. The indicator light may still be on, even with a battery that is weak. Do not leave dead batteries in the receivers.
Rechargeable Batteries:
(1)Rechargeable batteries are shipped in a discharged condition. They must be charged for 12 - 14 hours before using them. Make sure Transmitters and Receivers are turned OFF while charging.
(2)Williams Sound products are designed for use with a rechargeable battery (BAT 003) and matching charger (BAT 004, BAT 005, or CHG 1269). This is the only type of recharge- able battery and charger we recommend. The BAT 003 has an 8.4 V nominal voltage and 100mAh capacity, compared to only 7.2V and 60 mAh for other types of
