GETTING STARTED

Power

®
This unit operates from four AA batteries, or one DURACELL NiMH
rechargeable battery, or from 5 to 16 volts DC using the external power
cable. If the power cable is used, it automatically switches to it if the exter-
nal power is greater than the battery voltage. If for any reason the external
power fails, the unit automatically switches to the batteries.

BATTERIES

The unit requires four AA batteries. We recommend you use alkaline
batteries for the best trade-off between battery life and cost. However,
you can use nickel-cadmium (ni-cad), or lithium batteries. You can also
® ®
use rechargeable alkaline batteries such as RayOVac Renewals . With
the exception of lithium, none of the above batteries will last as long as
®
standard alkaline batteries. We recommend DURACELL brand, but
others will work. Do not use "heavy-duty" batteries or any type other
than the ones listed above. Do not mix different types of batteries. (For
example, don't use both alkaline and ni-cad batteries at the same time.)

Battery Installation

First turn the unit so that its back is facing
you. Push the two tabs to the left and re-
move the battery cover as shown at right.
Install the batteries according to this dia-
gram. (There's a decal in the battery com-
partment showing the correct polarity,
also.) Replace the battery compartment
cover and the unit is ready for use.

NiMH Battery

®
The DURACELL DR-121 nickel-metal
hydride (NiMH) battery replaces the four
standard batteries. It is sold as an acces-
sory, model BR-1 which includes a charger
custom designed for the DR-121. The bat-
tery never needs to be removed from the
unit, since the charger connects to the
GPS receiver and charges the DR-121. You can even use the receiver
while the battery is charging!
To install the NiMH battery, remove the battery cover and place the bat-
tery into the compartment as shown on the next page. It will only fit one
way, so if it's difficult to install, simply turn it over and drop it into place.
