Installation of FNB-80LI Battery Pack
The
FNB-80LI
is a high-performance Lithium-Ion bat-
tery providing high capacity in a very compact package.
Under normal use, the
FNB-80LI
may be used for ap-
proximately 300 charge cycles, after which operating
time may be expected to decrease. If you have an old
battery pack which is displaying capacity which has
become diminished, you should replace the pack with a
new one.
Install the
FNB-80LI
as shown in the illustration.
Close the Battery Pack Latch on the bottom of the
radio.

Do not attempt to open any of the recharge-
able Li-Ion packs, as personal injury or dam-
age to the Li-Ion pack could occur if a cell or cells
become accidentally short-circuited.
Battery Charging
If the battery has never been used, or its charge is de-
pleted, it may be charged by connecting the
PA-48B/C
Battery Charger, as shown in
the illustration, to the
EXT DC
jack. If only 12 ~ 15 Volt DC
power is available, the optional
E-DC-5B
DC Cable (w/ciga-
rette lighter plug) or
E-DC-6
DC Cable may also be used for
charging the battery, as shown in the illustration. “

” will blink in the display while the battery
is being charged. When charging is finished (approxi-
mately five hours), the display will change to indicate
“

” and the
BUSY/TX
indicator will blink blue.
Important Notes
:
Do not leave the charger connected to the trans-
ceiver for continuous periods in excess of 24 hours.
Long term overcharging can degrade the Li-Ion bat-
tery pack and significantly shorten its useful life.
If using a charger other than the
PA-48B/C
, or if
using a battery pack other than the
FNB-80LI
, fol-
low the appropriate instructions provided with the
charger/battery. Contact your Dealer if you have any
doubts about the appropriateness of the particular
charger or battery pack you intend to use.
