MICROPHONES
ITEC 5100 WIRELESS SYSTEM
3.2 Batteries
The WM-5100 is powered by 2 batteries of the type AA.
Please note, that in case of a battery exchange both batteries must be replaced by
a similar type at once. Be careful when inserting the batteries and check the correct
polarity: For both batteries the negative pole has to point towards the microphone
cap. The battery condition is shown on the LC display. The red battery indicator gives
information on the battery status as well: When turning on the system the indica-
tor shines for about one second. A permanent signal is a warning for a low battery
condition.
Remark
Used batteries are hazardous waste and have to be disposed accordingly. Some batteries (in particular low-end
products) can leak after long storage period and cause corrosion and ruining of the battery contacts. Use high
quality alkaline batteries of known brands, which also offer a longer lifetime.
3.3 Operation with accumulators
If you use accumulators together with your wireless microphone and the ITEC charger, check that in the battery
case accumulators of the original manufacturer and no batteries are inserted. In case a replacement of the accu-
mulators is needed use original parts only.
