3.The headphones will automatically retune if they lose the signal from the transmitter. However, you can also push the ON/OFF/SCAN button (C) to retune the headphones at any time. Allow 10 to 15 seconds for the headphones to lock into the transmitter. The amber “tuned” indicator light will come on after the headphones have been successfully tuned.

Note: Interference in the form of static and/or distortion can sometimes be heard. If this occurs, confirm the transmitter/headphone adjustments and indicators. If the problem persists, refer to the Troubleshooting section of this manual.

More Helpful Information

About Fixed-Level Audio Outputs:

A fixed-level, or line-level audio output is considered ideal since it provides an audio signal unchanged by adjustments to the audio source volume control.

Hint: Fixed-level audio outputs from stereo receivers/amps will typically be designated as Tape, Tape 1, and Tape 2 outputs, or VCR audio output connections. These outputs are frequently marked on A/V equipment as ‘TAPE OUTPUT,’ ‘TAPE OUT,’ ‘TAPE REC, or ‘TAPE RECORD or REC OUT.’

Please note: Jacks labeled PHONO, CD, LD, DVD or tape or VCR playback (PB) are INPUTS and will not work with the transmitter. Fixed- level outputs from TVs are usually marked as ‘Constant,’ ‘Fixed,’ or ‘Select.’ If they are not marked as such, they are probably variable outputs (see “About Variable-Level Audio Outputs” below). Outputs from VCRs are almost always fixed.

Hint: When connecting to the audio outputs of a VCR, remember that the VCR must be playing a tape or showing a TV channel for sound to be produced.

About Variable-Level Audio Outputs:

A variable-level output, such as a headphone jack or certain line audio outputs, provides an audio signal that changes with the volume level set on the audio source. As the volume of the audio source is adjusted up and down, so does the audio signal strength sent to the transmitter. This can affect the quality of sound generated by the headphones, and may require an adjustment of the volume level of the audio source to produce a signal strong enough for the transmitter.

Hint: On most bookshelf-type or compact stereo systems, inserting a headphone plug into the headphone jack results in automatic cut-off of the regular, or hard-wired speakers.

Hint: Most TVs, regardless of age or price, have variable outputs. If you are unsure which of your TV audio outputs is fixed, refer to the TV instruction manual. Some TVs have outputs that can switch between variable and fixed. When given a choice, fixed is always recommended.
