Recharging the ba 151 accuplug

Do not use rechargeable batteries until they are completely flat. If you do, they will be exhausted and cannot be recharged. This happens e.g. when flat accuplugs remain uncharged for some time. Please observe the two following rules:

If you notice that the accuplug is going flat, turn off the headphone and recharge the battery immediately. If you have a spare accuplug you can use it in the meantime.

Immediately recharge the accuplug after every use, no matter whether it is fully or only partly discharged.

Before using the accuplug for the first time, you should charge it for 24 hours in the transmitter’s charging compartment .

Please note: the accuplug is also recharged when the transmitter is switched off but remains connected to the mains.

Environment and health

Devices which operate on rechargeable batteries are environmentally friendly. They can be recharged many times whereas standard batteries are hazardous waste after use. In case an accuplug is defective or has been damaged due to exhaustive discharge, it can be recycled. Just return it to your specialist dealer. Here you can also get new Sennheiser accuplugs.
