If the battery fails the power-on self-test (or is in a heating cycle), it will be Red-X’ed and no backup
battery capability will exist:
Figure 20 - Battery Not Available Indication
If the battery status icon is Red-X’ed, the battery is not available for use and loss
of aircraft power will result in the unit turning off.
Prior to departure or entry into IFR conditions, verify that the battery is not
faulted (no red-X over the battery icon), and that a charge level of at least 80% is
shown.

Battery Duration
Battery duration is dependent on several factors; including age of the battery pack, display
intensity setting and ambient operating temperature. With a healthy battery, a minimum of 30
minutes of operation is guaranteed. Typical durations when operating at room temperature and a
reduced display brightness will be approximately 2 hours.
Note that the charge level indicated is an approximation of the remaining capacity of the battery,
and will dynamically adjust based on operating environment and conditions. For example,
diming of the display will extend the battery duration, and thus increase the percent charge
shown. Correspondingly, increasing the display brightness will reduce the battery duration and
thus decrease the percent charge shown.
