! CAUTION !
YOU SHOULD PAY ATTENTION TO THE
FOLLLOWING SAFETY INSTRUCTIONS!
Before setting receivers with rechargeable batteries into operation:
As soon as the rechargeable batteries are inserted in the receivers, these have to be charged immediately and completely in the designated SIR C 50 Charging Tray (equipped with Original beyerdynamic power supply).
Remember: Receivers not changing about 2 or 3 month will result in total discharge. This will cause the destruction of the rechargeable batteries! Therefore total discharged or defective rechargeable batteries will not be longer charged and have to be exchanged. In such a case you only may insert a new set of rechargeable batteries.
We recommend charging the rechargeable batteries every month for approx. 8 hours.
