Model 3430 Plus & 3440 Plus
LOW BATTERY WARNING
As described on pages 5–19 and C–10, the gauge constantly
monitors the voltage and charge status of the NiMH batteries. The
Battery Status function enables the operator to view the status of the
NiMH batteries, as well as the status (GOOD or BAD) of the charge
calibration.
In addition, if the battery voltage falls below a pre-determined
threshold, the gauge displays a low-battery warning symbol (
) in
the upper right corner of the Ready display.
By default (Normal setting), the low-battery warning is displayed
when the battery voltage falls below 6.2 V dc. At that point, the
gauge has approximately three hours of battery operating life left, or
less if the backlight is used. If the gauge is equipped with a GPS
unit (available only on Model 3440 Plus gauges), the remaining
battery operating life will be approximately one hour.
The Low Battery Warning function enables the operator to select
how early or late the low-battery warning is displayed. An early
setting provides more time between when the warning is displayed
and when the gauge shuts down. A later setting provides less
warning time.
To access this function, press 〈7〉 at the Extended menu shown on
page
9–1. The gauge displays:
Use the up and down arrows to scroll between the menu options. To

corresponding numeric key. To return to the Extended menu, press
