3 Precautions

1. Operate the headphones with two AAA size 1.2 V
rechargeable 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.

fire.
5. Operate the transmitter with the supplied 12 VDC, 200 mA

servicing to qualified service personnel only.

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.
