SETTING UP THE TX238 TRANSMITTER NOTICE: THE RECHARGEABLE BATTERIES ARE SHIPPED IN A DISCHARGED 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 transmitter is located.

SETTING UP THE RX237 RECEIVER STEP 1: INSTALL THE RECEIVER BATTERIES Insert the rechargeable battery into the bottom of the RX237 Receiver (see page 12). Place the receiver into the charger cradle built into the top of the TX238 Transmitter and let charge overnight. The spare battery can be plugged into the charging port located on either side of the transmitter. By keeping the spare battery charged, you can easily swap batteries when the one in use runs out and always have a fresh battery ready.
IMPORTANT: When you are done using the RX237, remember to UNPLUG the earphone, headphone, or neckloop from the receiver’s jack. The receiver will not turn off until the earphone/headphone is removed from the unit. Return the receiver to the charger when it is not in use! ADDITIONAL RECEIVER ADJUSTMENTS Balance Control: Use a small screwdriver to adjust the loudness balance between the Left and Right Earphones. See page 12.
