Battery Installation
The GA and Helicopter versions of Delta Zulu
battery-powered headsets require either two AA
batteries or the rechargeable lithium ion battery
cartridge (both included) for best performance.
A. Pinch the narrow buttons on each side of the
control box to release the battery cartridge.
One of the battery cartridges that came with
your headset holds two AA batteries. Slide
open the small door to insert the batteries
with the correct polarity positioning.
Getting Started
B. The LED flashes GREEN when the batteries are
charged and the power is ON.
C. When batteries begin to run low, the power LED
flashes RED. If the LED flashes RED during flight,
the headset will continue to operate for 5–10
more hours. Install new batteries as soon as you
can after the LED flashes RED.
Battery Types
Pilots can choose to use either two AA alkaline
or rechargeable lithium ion batteries. Lithium ion
batteries may provide improved battery life in
colder temperatures.
The easy to replace battery pack gives you the
option of using AA batteries or the included
rechargeable lithium ion battery pack.
