All of the Alarm options are set in the same way. The
instructions below apply to all of the Alarm settings. When
the beeper is turned on for alarms (see
Beeper
option) an
audible beep will be sounded for the alarm. A visual alert
is displayed for the alarm whether the beeper is turned on
or off.
Setting the Arrival Alarm
: The arrival alarm alerts you that
you have arrived at the destination of your GOTO route or
to the destination of any leg in a route you are navigating
on. This option allows you to set how close you must come
to the destination before the alarm begins to sound.
After the alarm sounds, you can reset the arrival alarm to a
shorter distance, but this shorter distance will apply to the
next target and not to the current one. If you want the
alarm to sound again when you come within a shorter dis-
tance to the current target, first select another target des-
tination and then reselect the original target.
Setting the PDOP Alarm
: This turns on or off the alarm
that can sound whenever MobileMapper Pro has lost its
ability to compute accurate position fixes due to poor
geometry of the GPS constellation. Generally, PDOP val-
ues less than or equal to “5” are indicative of good operat-
ing conditions. So it is a good idea to set this alarm to
“5.” To turn off the PDOP alarm, enter “00.”
