POWER
The receiver is powered by three AA batteries. lt can also be powered from
an external DC power source by using the optional Magellan Power/Data
Cable.
Batteries.
We suggest using AA alkaline batteries to power the receiver.
(Magellan Systems recommends Eveready Energizer
TM
batteries.) Alkaline
batteries will power the receiver for 5 hours or more of continuous operation.
To insert batteries,
remove the battery
tray as illustrated
and insert batteries
as indicated within
the battery tray.
When the battery
power level drops, a
warning message
will appear on all
displays
(LOW
BATT). The receiver
still has sufficient
power to operate for
up to 30 minutes if alkaline batteries are being used.
When the batteries no longer hold enough power to operate the receiver, the
receiver turns itself off. The batteries will still be able to maintain the memory
for a time, but the receiver can be operated only if external power is supplied
or if fresh batteries are installed.
lt is possible to use rechargeable batteries, but there are a couple of things
you should be aware of when using them. Commercially available NiCad
batteries typically have poor power performance after repeated use, and
rechargeable alkaline batteries maintain only 50% of the useful life of
standard alkaline batteries. Rechargeables also have a very sudden power
drop at the end of their charge. The drop may be so sudden that the battery
warning is not displayed, although memory can be maintained for a while.
