4. Charging The Receiver Batteries
Load the two AAA Ni-Cad rechargeable batter-
ies into the RX4 Receiver. Be careful not to bend
the plastic tabs when you replace the battery
door.
The RX4 Receiver must be charged before it can
be used for the first time. For charging, set the
receiver on top of the transmitter so that:
a) the RX4’s ON/OFF switch is pointed toward
the back of the transmitter, and
b) the charging pins on the TX4 engage the
charging contact holes in the receiver.
(See Figure 3.)
Make sure the Receiver Power Switch is
turned OFF while charging. (Figure 3.)
The Charging Indicator on the Receiver should
light. (See Figure 3.) If it doesn’t, make sure the
Transmitter power is connected and the charging
contact pins are properly engaged. The Receiver
trickle charges whenever it is placed on the
Transmitter / Charger Stand.
Press the Quick Charge Switch on the TX4 (See
Figure 1.) The Quick Charge Indicator on the
Transmitter will light.
In the Quick Charge mode, the batteries will
charge fully in about 6 hours. A fully-charged
battery will provide approximately 6 hours of
continuous Receiver operation.
Disposable AAA Alkaline batteries can be used
in the Receiver, but the Receiver should not be
placed on the charging stand.
5. Using the RX4 Receiver
Make sure your TV or Audio Source is turned
ON. Turn the receiver’s Power Switch to ON.
Place the headset on your head and locate the
Volume Control Wheel. (See Figure 3.) The
headband size can be adjusted by pulling or
pushing on each earpiece. Adjust the headset vol-
ume to a comfortable level.
The infrared receiver “eye” is located on top
of the headset. Do not cover it up or you will
lose reception.
Be sure to turn the Receiver OFF when it is
not in use.
In Case of Difficulty
If the system does not seem to be functioning:
1. Make sure that your television is plugged in and
turned on.
2. Make sure that the TX4 Transmitter is plugged in
and correctly connected to the TV or VCR’s
audio output.
3. If you’re using the TV Mic and not getting a sig-
nal, try turning the TV volume up slightly. Also,
try positioning the TV Mic directly over the TV
speaker.
4. Make sure that the RX4 Receiver has working
batteries.
5. Make sure you are not covering the RX4’s
infrared “eye”. Remove any objects obstructing
the line between the TX4 Transmitter and the
RX4 Receiver.
6. If you’ve installed the TX4 Transmitter other
than on top of the TV, make sure that its front
panel is facing the RX4 Receiver.
7. If the system still does not function, call Williams
Sound Corporation at 1-800-843-3544.
