Removing the headphone batteries:
To remove the batteries, open the battery lid as described above and pull the battery
out of the battery compartment by pushing the battery towards the spring until the
plus pole is released and slides out.
ATTENTION!
Never leave batteries inside the headphones for very long periods of time to prevent
any damage to the headphones from leaking batteries. Dispose of spent batteries
conforming to local waste disposal rules.
Check the remaining power of the headphone’ s battery:
When install two batteries into the battery compartments, switch on the headphone
by slide the switch to “ON” position. Check that the headphone’s power indicator lights

if the power indicator light is weak or turned off and the sound becomes distorted or
has a lot of noise.
