CALIBRATING THE BATTERY DISCHARGE GAUGE MKV
(MKV MPJ, DPJ, & REMOTE DIPLAYS)
MPJ & Remote Displays Joystick
(EX & TT-EX Only)
During normal operation the active drive is
displayed on the left half of the first line. The
left half of the second line is the BDG (Battery
Discharge Gauge). It provides information on
the remaining charge in the batteries. At full
charge solid blocks fill in all five (5) segments
between E (Empty) and F (Full). As the
battery becomes discharged, the farthest right
segments will progressively disappear a half
bar at a time until no segments appear be-
tween E and F. At this level the word RE-
CHARGE will appear on the second line to
indicate that the user should charge the
batteries as soon as possible.
Step 1: To verify the accuracy of the BDG,
use you multimeter to read a static battery
voltage. You can take the static voltage
reading from pin numbers 1 & 2, located on
the charger port. Once you have taken a
static voltage reading, record this number.
Step 2: Remove you test leads from your
multimeter, and plug in your Remote Pro-
grammer. Select the Calibration Menu and
arrow down until you see the Battery Level
Menu option. Press the Select key, and use
the up/down arrow keys to increase or de-
crease the static voltage reading value, so it
matches the recorded reading from your
multimeter.
NOTE: The static voltage reading can also
be viewed in the Current Status Menu, but
cannot be changed. All changes must be
made in the Calibration Menu.

Press the up or down arrow key, until

multimeter reading.
