Charging.
There is a DC power jack on the right hand ear cup. This accepts 9 to 14 volts. Connect the
supplied power supply to the headset and leave on charge for up to 20 hours. Alternatively
you can connect any 12 volt lead to the headset from your aircraft or automobile’s power
supply. We can supply extra charging leads on request. The batteries are NiMH. These have
no memory effect and you can part charge the batteries if required. If your headset is not flat
do not charge for 20 hours, instead charge for lesser time. You can discharge the batteries
quickly by plugging a music source to the headset and leave playing until the batteries are
flat, then charge for 20 hours.
Battery condition Indicator LED.
There is a charge indicator LED next to the on/off switch. When the LED is ‘ON’ the power
switch will be in the on position. When the LED is ‘OFF’, either the power switch is ‘off’ or the
batteries are low. The headset can be used when the LED fades off, but the battery condition
is low and should be charged. The headset can be charged with the switch in ‘on’ or ‘off’
position.
How to use the headset.

2. First turn the power switch on, this can be found inside the left hand ear cup. You
