INSTALLATION STEP 4: TESTING THE SYSTEM

Step 1: After the power cable and audio source are connected, the Power LED indicator on

the right side of the the bottom panel should light.

Step 2: Make sure the sound system is on and your audio source is active. Turn the Audio

Input Adjust if necessary. (See Figure 9.)

Step 3: Look at the TX10's bottom panel. With the input signal present and power

connected, three lights should be visible from directly underneath the panel: the

red Power LED, the amber Audio LED indicator, and the green Baseband LED.

At normal levels, the Audio LED should flash intermittently.

If the Audio LED does not flash at all, increase the audio level by turning the

Audio Input Adjust (accessible through the vent holes) with a small screwdriver or

similar tool. If the Audio LED is lit constantly, decrease the Audio Input Adjust.

The baseband and Baseband Indicator will shut off after the audio signal has been

absent approximately 30 minutes. If the Baseband LED is not on, check your audio

source.

Step 4: Take a receiver into the listening area and walk around to check the reception.

Make sure the transmitter and receivers are set to the same frequency. Make sure

the “eye” on the receiver is not covered up when in use. The receiver will not work

if it is placed in a pocket or purse; its eye must be able to “see” the transmitter

panel. A WIRM-1 Infrared Field Strength Meter may be used to check signal

strength if the TX-10 is operating on 95 kHz.

It may be necessary to adjust the angle of the transmitter to obtain the best

coverage. If coverage is not adequate, add one or more WIR TX8 Emitter panels to

the system. (See page 16, Using Multiple Emitters)

If the Audio LED is on, the Baseband LED is flashing, but you don’t hear anything

from the receiver, try a different receiver to be sure the receiver is not at fault.
