Battery Backup - Lowrance LMS-350A Installation And Operation Instructions Manual

Your current boat speed and
distance log are shown in the
upper left coner of the screen.
The calibration in percent is
shown in the upper right cor-
ner. Now enter the percent
change that is needed to make
the LMS-350's speed display
match your actual speed. For
example, if the LMS-350's
speed display is five percent
slower than your actual speed, then use a positive five percent. If the LMS-
350's speed display is five percent faster than your actual speed, then use
a negative five percent speed calibration. Press the key next to the "Calib
- +" label to change the factor from positive to negative.
When you have the speedometer calibrated, press the key next to the
"Exit" label to return to the sonar screen.

BATTERY BACKUP

The LMS-350A saves all system settings, such as windows, units of
measure, alarm settings, and more in memory that is powered by an
internal battery. This keeps the memory "alive" while the unit is turned off.
The LMS-350A gives you the ability to turn this battery on or off. Turning
it off causes the LMS-350A to
"forget" all system settings each
time you turn the unit off. This, in
effect, presets the unit each time
it's turned off.
To turn the battery backup off or
on again, press the MENU key
until the screen shown at right
appears. Now press the key next
to the "Disable Battery Backup"
label. The unit returns to the last
used sonar, GPS, windows, or
plotter screen with the battery turned off. To turn it on again, repeat the
above steps.
