The red operating indicator will light up as soon as you have connected the power adapter
to the outlet and the audio cable to a signal source. If the operating indicator light remains
off, switch on the audio source and increase its output volume level until the red indicator
light comes on. Our tests have shown the default volume levels of iPods, MP3 players and
other devices connected to the transmitter through the headphone jack does not have the
signal strength required by the transmitter. Raising the volume of your device will increase
the signal strength to the transmitter. The Power LED will light when the required signal
strength from your device is reached. We recommend that you keep the volume set on your
iPod or MP3 player at a minimum of ¾ of full volume.
CHARGING THE BATTERIES
1. Place the On/Off switch on the receiver headphones in the Off position.
2. Place the headphones on the transmitter, taking care to ensure that the charge
contacts touch the transmitter's charge prongs.
3. The charge process starts automatically and the green indicator light comes on. Be
sure to charge new batteries for 24 hours before using them for the first time in the
headphones.
WARNING:
Never attempt to recharge conventional dry cells.
Never use another type of battery or non-rechargeable batteries to replace the
rechargeable (LR03/AAA) batteries supplied. When the headphones are not in use, move
the switch to the OFF position to avoid damaging the batteries. The batteries must always
be fully charged before use.
IMPORTANT:
When replacing the batteries or disposing of the unit, always comply with applicable laws
relating to the disposal of batteries. Please place them in a proper disposal container to
ensure that they are eliminated safely and in an environmentally friendly way.
