1 Introduction

Dear customer:
Thank you for purchasing an AKG product.
The HEARO 777 SURROUND wireless headphone system is based on advanced UHF transmission technology. The IVA processor
and the Dolby Surround Pro Logic decoder provide optimum spatial reproduction for speech, music, TV and video sound, multimedia
PC applications, and video games. An Autotuning function that automatically tunes the receiver to the carrier frequency selected on
the transmitter adds to the user-friendliness of the HEARO 777 SURROUND
In order to make optimum use of the benefits of your HEARO 777 SURROUND, please take a few minutes to read the instructions
below carefully before operating the equipment.
Please keep the manual for future reference.

2 Precautions

1. Operate the headphones with two AAA size 1.2 V rechargeable (supplied) or 1.5 V dry batteries only.
2. Never try to charge dry batteries using the transmitter's charging feature.
3. Before charging the headphones batteries, always make sure that the batteries in the headphones are rechargeable types.
4. Dispose of spent dry or rechargeable batteries conforming to local waste disposal rules. Never throw batteries into the fire.
5. Operate the transmitter with the supplied 12 VDC, 300 mA AC adapter only. Check that the AC voltage stated on the AC
adapter is the same as that available in your country. Using the transmitter with a different AC adapter voids the warranty.
6. Always switch the headphones OFF after use.
7. Never try to open the headphone or transmitter case. Refer servicing to qualified service personnel only.
8. Never place the equipment near heat sources such as radiators or electric heaters, or expose it to direct sunlight, excessive dust,
humidity, rain, vibrations, or impacts.
9. Never use alcohol, petroleum-based cleaners, or paint thinners to clean the headphone or transmitter case.
10. If you do not use your transmitter for an extended period of time (e.g., when traveling), disconnect the AC adapter from the AC
outlet.
11. Also refer to section 7 Important Notes.
