Williams Sound WIR 238, WIR 239 manual Setting UP the TX238 Transmitter

SETTING UP THE TX238 TRANSMITTER

NOTICE: THE RECHARGEABLE BATTERIES ARE SHIPPED IN A DIS- CHARGED STATE. THE BATTERIES MUST BE CHARGED OVERNIGHT BEFORE USING THE SOUNDPLUS™ TV INFRARED SYSTEM.

The WIR TX238 Transmitter may be placed on top of a TV or shelf. Place the TX238 Transmitter where it is clearly visible from your listening position.

Infrared light behaves like visible light, so it is blocked by solid objects. This confines the signal to the room where the trans- mitter is located. The transmitter cannot be placed inside or behind anything except glass. The maximum operating distance is approximately 30 feet (9 m).

Ideally, the TX238 Transmitter should be at ear-level height or above. The infrared light pattern is much like a floodlight “cone” as it leaves the transmitter, with the best reception inside the cone.

Sunlight can cause infrared interference in the form of a buzz, hiss, or static. Thus, the system cannot be used outdoors and may not work properly inside if a lot of direct sunlight is pres- ent. Closing drapes or blinds will help if sunlight is a problem.

Any number of receivers may be used with the TX238 Transmitter, but use only one transmitter in a room at the same time. Otherwise, interference will occur.
