THE BATTERIES MUST BE CHARGED OVERNIGHT BEFORE USING THE SOUNDPLUSTM 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.

When the receiver is placed into the charging cradle built into the top of the transmitter, the center charging indicator on the front of the TX238 will turn on. When the spare battery is plugged into the left or right battery charging port on the trans- mitter, the corresponding charge indicator light will turn on. STEP 2: CONNECT THE TRANSMITTER TO THE AUDIO SOURCE Use the supplied red and white RCA audio cables to connect the TX238 Transmitter directly to the TV, VCR, or stereo “AUDIO OUT” jacks. If your television does not have “AUDIO OUT” jacks, you will need use the supplied TV microphone. See page 9 for TV microphone instructions. OR 4 ® 7 STEP 2 (CONTINUED): NOTE: Some televisions have FIXED output and others have VARIABLE output. If available, FIXED output should be selected. Consult your television manual for more information. “Fixed” output means the volume on the television will not change when the volume is increased, decreased, or muted. “Variable” output means the volume on the television will change when it is increased, decreased, or muted. If variable out- put is the only output available on your television, we recom- mend using the supplied TV microphone. See page 9 for TV microphone instructions. STEP 3: SELECT STEREO OR MONO OPERATION Note: Choose 1 of 3 transmitter setup options below and on page 9. Verify receiver compatibility on left. Important: If your system is packaged with the WIR RX239 (neckloop) Receiver, you must setup the WIR TX238 Transmitter to operate in 2.3 MHz (mono) mode. See 2.3 MHz (mono) instructions on page 9. The WIR RX239 (neckloop) Receiver will NOT work while the transmitter is in stereo or 2.8 MHz mode. If your system is packaged with the WIR RX237 or WIR RX238 Receiver, you can choose to operate the WIR TX238 in stereo OR mono (2.3 or 2.8 MHz) operation.
