Charging the batteries
Prior to operating the headphones, the batteries have to be charged. Four 
rechargeable NiMh batteries are supplied.
Insert two of the batteries into the battery charging bays of the transmitter. 
The two lights “Battery 1” and “Battery 2” of the transmitter will light to indicate 
that the batteries are being charged.
In order to operate the headphones quickly, leave the batteries inside the 
charging bays for a few hours. In order to fully charge the batteries, leave 
them inside the charging bays for 48 hours.
After removing the batteries from the transmitter for use with the headphones, 
insert the second pair of the batteries into the charging bays. The second pair 
will be charged while the first pair is being used inside the headphones. After 
the headphones stop working because of low batteries, switch the first pair of 
batteries with the pair inside the transmitter charging bays.
The batteries can remain inside the charging bays for more than 48 hours. 
The transmitter will keep the batteries fully charged while inside the charging 
bays.
