Chapter 2 GETTING STARTED
Introduction
Before your ProMARK X is ready for use, there are several tasks that must be
completed. This chapter is intended to take the reader through these tasks
and prepare the user for taking position fixes with the receiver. This chapter
will cover operating the ProMARK X from either alkaline or NiCad batteries,
as well as from external power sources. Also covered in this chapter are the
keypad layout, entering data from the alphanumeric keys and initialization
of the starting position. After a few steps this chapter will guide the user
through obtaining a position fix and understanding the acquisition and
position fix displays.
Batteries
The ProMARK X requires that six AA batteries be installed at all times, even
when operating power is being provided from an external source. The
batteries are needed to maintain the unit’s memory between operating
sessions. (ProMARK X has a rechargeable lithium backup battery to retain
memory should the primary power source be lost.)
Battery power is provided by six AA alkaline batteries; we recommend
Eveready Energizer™ batteries. You can also use the Magellan Rechargeable
Battery Pack.
NOTE
NiCad and rechargeable alkaline batteries are never recharged
while in the unit.
Alkaline batteries provide up to 3 hours of continuous use. The drop off at
the end of their lives is gradual enough to allow the unit to display two power
warnings: an initial warning that battery power is low, and a second warning
that there is insufficient power remaining to continue operation.
The ProMARK X can also be powered from the Magellan Rechargeable
Battery Pack. The battery pack contains six high-capacity nickel cadmium
batteries, which are compatible with the power requirements of Magellan
products. The battery clip is not required when using the battery pack and
a connector for the charging adapter is available separately.
It is possible to use individual rechargeable batteries, but we cannot
recommend their use. Commercially available NiCad batteries typically have
