	1 Precautions
Operate the K 105 UHF headphones with two AAA size 1.2 V rechargeable (supplied) or	1.1
1.5 V dry batteries only.
Never try to charge dry batteries using the transmitter’s charging feature.	1.2
Before charging the headphones batteries, always make sure that the batteries in the head-	1.3
phones are rechargeable types.
Dispose of spent dry or rechargeable batteries conforming to local waste disposal rules.	1.4
Never throw batteries into a fire.
Operate the T 105 UHF transmitter with the supplied 9 VDC, 200 mA AC adapter only.	1.5
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.
Always switch the headphones OFF after use.	1.6
Never try to open the headphone or transmitter case. Refer servicing to qualified service	1.7
personnel only.
Never place the equipment near heat sources such as radiators or electric heaters or	1.8
expose it to direct sunlight, excessive dust, humidity, rain, temperatures below freezing, or
impacts.
Never use petroleum-based cleaners or paint thinners to clean the headphones or trans-	1.9
mitter.
If you do not use your headphones system for an extended period of time (e.g., when tra-	1.10
veling), disconnect the AC adapter from the AC outlet.
