AUX6 - Batteries
The supply voltage indicates the approximate power being applied
to the receiver. This screen is intended to give you a rough indica-
tion of the supply voltage. It is not a digital voltmeter and can be off
by 0.5 VDC or more. Use it like you would a car battery indicator.
The voltage should remain constant when the generators are on, and
drop off slowly when running on the boat's batteries. This is also
where you reset the Lithium battery age. Press the E key and select
the Reset Age softkey after you replace the Lithium battery. Refer to
the Installation & Service Manual for instructions on replacing the
memory backup battery. This battery has a normal life of about 2
years.
