Ideally, the TX295 Transmitter should be at ear-level height or above. The infrared light pat-
tern 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 present.
Closing drapes or blinds will help if sunlight is a problem.

Any number of receivers may be used with the TX295 Transmitter, but use only one transmit-
ter in a room at the same time. Otherwise, interference will occur.

If you are using the TV Microphone, plug it into the “Mic” jack on the TX295 as shown. Use
the Velcro strip supplied to attach the microphone near the loudspeaker of your TV. The micro-
phone will allow you to play the TV at lower volume for other listeners and will pick up other
important sounds like the telephone or doorbell ringing.

To use the supplied Audio Cable to connect the TX295 Transmitter directly to TV, VCR, or
other equipment output jacks:  

Connect the LEFT RCA plug from the TV (or VCR) speaker output into the LEFT RCA
jack on the TX295 transmitter.  Remember, the Stereo/Mono Selection Switch must be in
the “L” Left position to transmit in 95 kHz!  

When the Audio Inputs are used, the Mic input is automatically disabled.

NOTE:  The TX295 has an automatic shut-off feature that turns the Transmitter off 90 seconds
after the audio signal is no longer present.
