Re-lock the bottom plate by carefully pressing the
hinged latch cover back into its normal operating
position.
If the battery has never been used, or if its charge is
depleted, it may be charged by connecting the NC-
66B/C/U AC Adapter to the
EXT
DC jack for 2 hours.
If only 12-24-volt DC power is available, the op-
tional E-DC-15 DC Adapter (with its cigarette lighter
plug) may also be used for charging the battery.
The transceiver must be turned off to charge the
FNB-52LI battery using the NC-66 or E-DC-15 (the
FB A-20 cannot be charged).
Operating the transceiver from the NC-66 allows 1
watt high transmit power, but the battery does not
charge while the transceiver is on.

Installing the FBA-20 (Option) Alkaline
Battery Case
The optional FBA-20 Battery Case allows receive
monitoring using a single "AA" size alkaline battery.
An alkaline battery can also be used for transmission
in an emergency, but power output is only 100 mW,
and battery life is short.
The FBA-20 includes a DC-DC converter which dou-
bles the voltage of the alkaline battery to approxi-
mately 3V.
To Install an Alkaline Battery in the FBA-20:
Slide the battery into the FBA-20 so that the negative
[-] side of the battery touches the spring contact
inside the FBA-20.
Referring to the diagrams on the previous page, un-
lock the bottom plate by pushing the latch in the
OPEN direction, and install the FBA-20 as illus-
trated, with the l +] side facing the bottom of the
transceiver.
Re-lock the bottom plate by carefully pressing the
hinged latch cover back into its normal operating
position.
The FBA-20 does not provide connections for charg-
ing, so the NC-66B/C/U or E-DC-15 may safely be
connected to the EXT DC jack when the FBA-20 is
installed.
