Replace the compartment cover and follow
the charging instructions included with the
BR-1.
(Note: The DR-121 is the only battery that
can be recharged in this unit! Using the ex-
ternal power cable alone does not charge the
battery! You must use a charger supplied by
Lowrance in order to charge the battery. Also,
this charger will only charge a DR-121. It will
not charge any other type of battery, includ-
ing ni-cads or rechargeable alkallines.)
External Antenna
Although this GPS receiver is extremely sen-
sitive, it can be used in locations where the
built-in antenna simply cannot receive signals from enough satellites. A
second connector on the back of the unit is for an external antenna. The
Lowrance model EA-2 antenna plugs directly into this connector. Other
antennas may work. If you use an antenna other than Lowrance, it will
need to be a passive antenna. This unit does not supply power to the
antenna.
