4-7
When you are within 500
feet (152.4 meters) of the
destination, the NAV 5000
beeps and the fourth line of
the screen reads "CLOSE."
ON/OFF
The On/Off key turns the NAV 5000 on and off.
When the Battery Saver is on, the NAV 5000 will take fixes for two
minutes after POS, NAV, or VEL is pressed, and then shuts off if no
other function keys are pressed. When the Battery Saver is off, the unit
operates continuously until the second battery warning appears (see
page 4-8). In continuous use alkaline batteries power the receiver for
about 10 hours.
When operating from external power, the unit operates continuously
until disconnected or until turned off with the ON/OFF key.
