rotate FREQ. ADJUST (17) all the way CW or CCW because optimum reception may not always be guaranteed at the ends of
the frequency band.
8.
Set the VOLUME control (6) on the headphones to the desired volume level.
Note: If the transmitter signal is disturbed, e.g., by reflections (multipath reception) or shadow effects, the headphones will auto-
matically mute. This function eliminates interference related noise.
6.6 SELECTOR Switch (Fig. 1)
The SELECTOR switch (13) lets you select the desired reproduction modes of your HEARO 777 SURROUND.
The SELECTOR switch (13) has three positions:
Left: STEREO for standard stereo reproduction. The input signal is transmitted unchanged.
In stereo mode the green STEREO LED (10) will light.
We recommend STEREO mode for stereo music and speech reproduction.
Center: IVA STEREO. The IVA processor converts the stereo input signal to a binaural signal. The ear matching function provides
a natural sonic perspective with no inside localization.
In IVA stereo mode the green IVA STEREO LED (11) will light.
We recommend IVA STEREO mode for 3-D music and speech listening.
Right: IVA SURROUND. The Dolby Surround Pro Logic Decoder, in conjunction with the IVA processor, simulates five loudspeaker
channels (front left, center, right and rear left and right) for surround sound in the headphones.
In IVA SURROUND mode the green IVA SURROUND LED (12) will light.
We recommend IVA SURROUND mode for radio drama, TV, PC applications, video, surround sound and pop music recordings.

7 Important Notes
1.
Operating switches on or connecting the transmitter to your audio source may cause clicks which at high volume settings may
affect your hearing. Therefore, be sure to set the VOLUME control on the headphones to minimum before switching bet-
ween different sources (tuner, turntable, CD player, etc.) or connecting the transmitter.
2.
Listening over headphones at high volume levels, particularly over extended periods of time, may damage your hearing.
3.
Your HEARO 777 SURROUND is a radio frequency device that conforms to the strict European and FCC standards. For
physical reasons that are not related to the quality of the product, extremely strong interference sources may affect reception. In
order to maintain interference-free listening pleasure, do not operate your HEARO 777 SURROUND in the close vicinity of radio
equipment, cellular telephones, or directly above TV or computer monitor picture tubes. The supplied connecting cables are long
enough to allow the transmitter to be placed at a safe distance from interference sources.
Interference caused by other users of the 914 or 864 MHz LPD band are beyond AKG's control.
