Thales Navigation Mobile Mapper - Manual (Page 10)

Installing the Batteries
MobileMapper uses two AA
batteries that are installed
from the back through the bat-
tery cover. To remove the bat-
tery cover, push the two
buttons on the cover fully to
the left and lift the battery
cover away from the receiver.
Insert the new batteries as
shown opposite, making sure
that the batteries are installed with the correct polarity. Re-
place the cover and push the two buttons fully to the right.
Verify that the cover is locked in place.
Turning Power On/Off
In the Power-On procedure described below, it is assumed
that the unit has already been used in a working session and
so position data is available from the former working session
to help MobileMapper compute its position.
• To turn the unit on, press the PWR button. The Start-up
screen appears, followed by the Database Copyright
screen and the Agreement screen. After accepting the
warning information, the last navigation screen you were
viewing at the end of the last session will be displayed.
If the last navigation screen view was the Map screen,
the last zoom scale setting will be used.
• To turn the unit off, press the PWR button. The Power
Down screen is displayed.
Doing nothing will turn off the unit at the end of the
countdown sequence.
Pressing the PWR button again will turn off the unit
immediately.
Pressing ESC will cancel the Power Down sequence.
Battery Life
You can expect up to 16
operating hours from 2
Li-ion AA batteries with
the backlight turned off.
Using the backlight will
shorten the battery life
significantly. With the
backlight on continu-
ously, you can expect
about up to 8 hours of
usage from the two Li-ion
batteries that came with
your MobileMapper.
The very first time you
use your MobileMapper,
or after erasing all the
data from memory, the
Power-On procedure is
longer than described
here because the unit
having no position in
memory, initialization is
needed to help the unit
track satellites (see 1st-
time use on page 6).
