Firehawk M7XT Operación E Instrucciones página 16

4. When an evacuation command has been sent to the user
(if the optional FireHawk M7XT Telemetry Module is in
use), the FireHawk M7 HUD or I-HUD will display an alter-
nating red and orange LED until the evacuation has been
confirmed.
5. The FireHawk M7 HUD or I-HUD has a photo sensor that
automatically adjusts the brightness of the LEDs based on
the intensity of the ambient light measured outside of the
facepiece.
6. The FireHawk M7 HUD or I-HUD indicates a low battery
condition in either the HUD or FireHawk M7XT Power
Module by a flashing yellow LED. A user can confirm the
power module low battery indicator by viewing the low
battery indicator on the control module display. If this con-
dition exists, return to fresh air, and replace the batteries
immediately. See Replacing Batteries in the FireHawk M7
HUD or I-HUD.
