tions below carefully before operating the equipment.

3 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 head-
phones are rechargeable types.
4. Dispose of spent dry or rechargeable batteries conforming to
local waste disposal rules. Never throw batteries into fire.
5. Operate the transmitter with the supplied 9 VDC, 500 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, temperatures below freezing,
or impacts.
9. Never use alcohol, petroleum-based cleaners, or paint
thinners to clean the headphones or transmitter.
10. If you do not use your headphones system 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.
