7.3.3 Battery Care
1. Always store the batteries inside the receivers in charged condition. Storing rechargeable batteries uncharged
would significantly reduce their useful life.
2. If you do not use a receiver for a long period of time, charge its battery to capacity every one or two months, no
matter to what level the battery has been charged before. This is important because the battery will self-discharge
even when the receiver is switched off.
3. Do not store receivers in trickle-charging mode in the CU 50 indefinitely. This may reduce the usfeul life of the bat-
tery inside the receiver. After a conference has ended, charge all receivers to capacity and switch power to the
CU 50 off.
