Charge my battery

How do I charge my headset battery?


For best performance, use only AAA Alkaline or Lithium replacement batteries with the H300.

To replace the battery:

  1. Open the battery door at the back of the headset.
  2. Remove the old battery, if necessary. 
  3. Insert a new battery so the (+) and (-) markings match the ones in the battery compartment.
  4. Close the battery door.
