Garmin GPS 150 - Manual (Page 67)

In the event of power failure, the GPS 150 can automatically turn off the display
while using battery power, if desired. This will greatly increase the GPS 150’s battery
life while navigating without aircraft power. During the time the display is off, the
GPS 150 will continue to navigate and track satellites, but not display information
until a key is pressed, or a knob is turned.
To set the display timeout:
1. Press
S
and rotate
O
until the Battery Saver page is displayed.
2. Press
C
and rotate
K
until the desired value is displayed (0, 30, 60, or 90 seconds).
Entering 0 will leave the display on at all times.
3. Press
C
to complete.
The trip timer (described in Section 1, page 20) can be configured to run when
the power is on, or when your ground speed exceeds a specified minimum.
To change the trip timer settings:
1. Press
S
and rotate
O
until the Trip Timer Settings page is displayed.
2. Press
C
and rotate
K
to display either ‘pwr is on’ or ‘gs exceeds’.
3. If you choose ‘pwr is on’, press
C
to complete.
4. If you choose ‘gs exceeds’, rotate
O
to highlight the speed field.
5. Use
K
and

to enter the ground speed to be used as the minimum.
