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 310?

Yes. However, the battery life of your GPS 310 will be

diminished with the use of NiCad batteries.

Can I attach my GPS 310 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 310,

memory will be retained for up to one month, even with

dead batteries. (With good batteries installed, you can store

your GPS 310 for six months without losing any memory.)

When you remove batteries, you have 30 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.
