FBA-20 Precautions: 
• The FBA-20 is designed for use only with an 
AA-type alkaline cell. 
• 
If 
you do not use the 
VX-IR 
for a long time, 
remove the battery from the FBA-20, as battery 
leakage could cause damage to the FBA-20 and/or 
the transceiver. 
• Avoid touching the electrode area 
of 
the bottom 
plate, as it is sharp! 
• Even with afresh battery, the 
Ci! 
icon will blink 
when the 
PTT 
switch is pressed. 
Battery Life 
The 
VX-IR 
includes many functions that can be 
enabled to extend battery charge life, so it is difficult 
to estimate how long the battery charge will last 
under all conditions. However, the following table 
provides some rough approximations under specific 
conditions. Your mileage is likely to vary. 
When the battery is almost depleted, Ci! appears at 
the lower right 
comer 
of 
the display, indicating that 
the battery needs recharging 
or 
replacement very 
soon. 
If 
you continue operating, the 
Ci! 
icon starts blink-
ing, indicating that battery voltage is critically low: 
the battery should be recharged or replaced at once 
(or the radio turned off).

The actual battery voltage is displayed briefly when 
the 
VX-!R 
is first switched on, and can be displayed 
manually on the LCD, by following the instructions 
on page 46. 
Battery capacity may be reduced during extremely 
cold weather operation. Keeping the radio inside 
your parka may help preserve the full charge capac-
ity. 
AC 
Operation Using the NC-668/C/U 
The 
YX-IR 
can 
be 
operated from your house current 
by use of the supplied NC-66B/C/U AC Adapter. 
To 
use the NC-66B/C/U, 
tum 
the transceiver off, then 
plug the miniature connector 
of 
the AC Adapter into 
the EXT 
DC 
jack 
on the side 
of 
the radio. Now plug 
the AC Adapter into the wall outlet. You 
can 
now tum 
on the transceiver. Transmitter 
power 
output is 1 watt 
(High) and 200 mW (Low) in this case.
