Battery installation
The Tango headset requires two rechargeable
lithium ion batteries, except the panel powered
version, which requires only one (batteries included).
A. Open the headset battery compartment door by
pressing down on the battery door release. Align
the contacts on the battery with the contacts
in the compartment and close the battery
compartment door.
B. To access the panel interface battery
compartment door, open the jacket, then
open the battery compartment on the back of
the panel interface. Align the contacts on the
battery with the contacts in the compartment,
and close the battery compartment door.

continue to flash red and the audible tone will play
after increasingly short intervals as the battery drains
to zero.) Because lithium ion batteries — unlike Ni
Cad batteries — do not develop a “memory” and do
not need to be fully discharged before recharging,
we recommend that you charge your batteries
before each flight. Heavy Bluetooth usage can
significantly reduce battery life.
The headset and panel interface include Auto
Shutoff™ to preserve battery life. Learn more about
this feature on page 12.
