Powering the Headphones

The AHP612 headphones can be powered by three rechargeable

AAANickel Metal Hydride (Ni-MH) batteries (supplied, (R)) or any other NiCd or alkaline batteries.

Inserting the Batteries

1.Remove the left ear-cushion.

2.Insert batteries following polarity (“+” and “–”) as diagrammed inside the battery compartment.

Charging batteries

•Make sure that the headphones’ “ON/OFF/SCAN” button (C) is turned off and the LINK indicator light is unlit.

•Place the headphones on the transmitter, ensuring that the charging contacts (E) on the left ear cup sit securely on the charging contacts on the transmitter base. The CHARGE indicator light (I) on the transmitter will turn on when the headphones are seated properly.

Charging Schedule:

Use: Charge Time: Average 10–12 hours

Play Time: 6–8 hours*

*Play time as shown above reflects use of batteries in good condition.

Warnings:

•The AHP612 headphones can also be powered by three AAA alkaline batteries (not included). You may experience slightly longer play time with alkaline batteries, but you will not be able to recharge them, as you can with the supplied NiMH or NiCd rechargeable batteries.

•The AHP612 built-in charger will charge rechargeable NiMH (supplied, (R)) or NiCd batteries only. DO NOT attempt to charge any other batteries except those specified above.

•The included NiMH batteries can be charged at any time, without any adverse memory effect, whereas NiCd batteries must be fully discharged before they can be recharged in order to avoid a reduction in performance. For this reason we recommend continued use of the supplied NiMH.

•Over time, with repeated use, even Ni-MH batteries will eventually wear out. If, after a full charge, you notice a) dramatically decreased playing time, b) the power indicator light begins to dim quickly and/or c) static interference occurs within a short time of turning the headphones on, it may be time to replace the batteries.

Notes:

•The charger will not overcharge the batteries if left to charge longer than shown above. However, if you do not intend to use the headphones for an extended period of time, it is recommended that you unplug the transmitter from the AC power outlet.

•Battery life depends on frequency of use, time, and care.

Adjusting the Transmitter

Transmitter Front View:

(I) Charge indicator light

(J) Audio level indicator light

Transmitter Back View:

(K) Channel select switch

(L) Input level control

(M) RCA audio input jacks

(N) Transmitter power input jack

•Turn ON your audio source (i.e., A/V receiver, TV, portable CD player, etc.) and play music at a normal listening volume.

•Set the channel select switch (K) on the back of the transmitter to 1, 2 or 3. The transmitter provides three different broadcasting frequencies. In the event that you experience poor reception or interference, try choosing a different frequency by moving the channel select switch to another position.

•Turn the input level control (L) down (all the way to the left — your left when looking at the front of the transmitter).

•Check the audio level indicator light (J) on the front of the transmitter. If the light flickers intermittently (about half the time), proceed to the next section. If the light does not blink or is flickering very rapidly, turn the input level control (L) slowly up (to the right — your right when looking at the front of the transmitter) until the light flickers intermittently.

Note: if the light does not flicker, please check the following:

•Confirm that the transmitter AC power adapter (O) is securely connected.

•Confirm that the audio input cable coming out of the transmitter is securely connected to the audio source output (TV, A/V receiver, etc.).

•Turn the input level control (L) slowly up (to the right — your right when looking at the front of the transmitter) and check if the transmitter is connected to a variable audio output, such as a headphone jack or TV audio output. Adjust the volume on the audio source up or down as necessary to make the audio level indicator light (J) flickers intermittently. If you are unclear as to the kind of output (variable or fixed) you are using, please see the section entitled MORE HELPFUL INFORMATION.
