13.Power Off Timer
Conserving battery life is important to any handheld GPS
user. The Power Off Timer option provides another tool
in saving battery life.
Selecting
On will allow you to select the mode and how
long MobileMapper will stay powered on.
- If the Power off mode you select is Time , then the Power off
Timer field allows you to select time that MobileMapper
will remain on before automatically powering off is no
keys are pressed (1 2, 4, 10, 30 or 60 minutes).
If the
Power off mode you select is Position , the Power Off
Timer field sets how soon MobileMapper will be powered
down when the position has not changed and if no keys
have been pressed.
14.Contrast
This option allows you to set the screen contrast. After
selecting this option, a new screen appears on which you
can set the percentage of contrast using the left/right
arrows to respectively decrease or increase that percent-
age. The impact of your contrast setting upon different
color bars is instantly shown in the lower part of the
screen.
15.Light Timer
This option allows you to set the time interval that will
be used to turn off the display backlight when not in use.
Times available are: 30 seconds, 1, 2, 4 or 10 minutes, or
Timer Off.
After selecting the
Light Timer option from the Setup
menu, use the up/down arrow to highlight the desired
choice and then press ENTER.
Default: Off
It’s a good idea to use
this option when you
transport your
MobileMapper unpro-
tected in a bag. This will
prevent the batteries from
being entirely dis-
charged after the PWR
button has been inadvert-
ently depressed.
Default: 4 minutes
