Headset Battery Installation
IMPORTANT: Charge the batteries for 8 hours prior to first use. You must only use
rechargeable batteries (included). Do NOT use alkaline batteries or you will
severely damage the unit.
The wireless headset (
B
) requires two AAA rechargeable batteries (included). To
access the battery compartment, remove the battery cover on the back side of the
headset (refer to Fig. 3). Insert two AAA rechargeable batteries matching positive (+)
to positive (+) and negative (-) to negative (-) and replace the battery cover. Do
NOT
use alkaline batteries.
Charge the batteries for 8 hours prior to first use. Be sure the headset is turned off and
the transmitter is plugged in to an electrical outlet. The transmitter will automatically
turn on when the AC adapter is plugged in. Place the headset in the charging base of
the transmitter (refer to Fig. 4). The red charging indicator light on the left side of the
transmitter will illuminate. On a full charge, the battery life is approximately 10 hours.
Recharge when the volume begins to weaken and the power indicator light on the
headset begins to dim. It will take 6 hours to fully charge the headset after the initial
charge. The charging indicator light will turn off once the headset is fully charged. If
the charging indicator light does not turn on when you put the headset in the charg-
ing base, the headset is at least 70% charged. It will not charge until the headset is less
than 70% charged. This helps to prolong the life of the batteries.
For long periods of non-use we suggest removing the batteries.
The batteries need to be replaced when they last much less than the expected time
(approximately 10 hours) after proper charging. Be sure to replace
ONLY
with AAA
NiMH rechargeable batteries. Do
NOT
use alkaline batteries.
Operating the System
1.
Place the transmitter at or close to your eye level when you are sitting. There
should be nothing obstructing the transmission of the infrared light rays from the
transmitter to the receiver in your headset (refer to Fig. 5). The transmitter must be
within 33 feet (10 meters) of the headset for the system to work properly.
NOTE:
Avoid exposure to direct sunlight. Direct sunlight may interfere with the
reception. It is also subject to interference from treadmills.
2.
The transmitter will automatically turn on when the AC adapter is plugged in. Four
red lights on the front of the transmitter will illuminate.
3.
Turn the headset on by sliding the power switch to the “ON” position. The red
power indicator light will illuminate. To prevent possible damage to your ears, be
sure to lower the volume on the headset before putting it on.
4.
Put the headset on making sure the right ear piece ( ) goes in your right ear and
the left ear piece ( ) goes in your left ear. The ear pieces do not go inside the
ear. They rest just outside. The headset should hang under your chin with the “TV
Listener K4” logo facing away from you (refer to Fig. 6).
