BATTERIES
WARNING: The AW770 built-in charger will charge Ni-Cd batteries only. DO NOT
attempt to recharge alkaline or rechargeable alkaline batteries, as this will damage
the headphones and/or transmitter.
Over time, with repeated use, Ni-Cd batteries will eventually wear out. If, after a full
charge, you notice a) dramatically decreased playing time, b) the Power Indicator
lilht (C) begins to dim quickly and/or c) static interference occurs within a short
time of turning the headphones on, it may be time to replace the batteries.
Suitable replacements of a like or similar type should be available where batteries
are sold.
NfIte: Battery life depends on frequency of use, time, and care (fully discharging the
batteries regularly, as described above.)
If you have questions regarding battery replacement, please contact our Customer
Service Department at 1-800-732-6866.
