Why won’t the receiver accept the coordinates higher than 59
seconds when I am inputting coordinates?
The most common cause of this is you are trying to enter
coordinates that are in degrees/minutes while your receiver
is set to degrees/minutes/seconds. Since the last two digits
in degrees/minutes is in hundredths (00 - 99) and degrees/
minutes/seconds can be no higher than 59 (00 - 59),
inputting a number higher than 59 while in deg/min/sec
results in an error and the receiver does not accept the entry.
Can I use NiCad Batteries in my GPS 300?
Yes. However, the battery life of your GPS 300 will be
diminished with the use of NiCad batteries.
Can I attach my GPS 300 to external power?
Yes. However, this requires the optional external power
cable available from your dealer or Magellan Corporation.
Will I lose all my landmarks when my batteries die?
No. As long as you leave the batteries inside the GPS 300,
memory will be retained for up to one month, even with
dead batteries. (With good batteries installed, you can store
your GPS 300 for six months without losing any memory.)
When you remove batteries, you have 20 minutes to install
new batteries before memory is lost.
Why does my speed and elevation sometimes jump around?
For security reasons, the U.S. Government introduces small
errors (selective availability) which can affect positioning
information. These errors are most noticeable while viewing
speed, heading, and elevation.
