I Optional battery case

➥ Install 2 R6 (AA) size alka-
line batteries into the op-
tional BP-216
.
CASE
• Be sure to observe the cor-
rect polarity.
A built-in step-up convertor in the BP-216 increases the
voltage to 5 V DC.
Approx. 100 mW of output power is possible with the BP-
216 operation. Also, no transmit output power selection is
available.
Keep battery contacts clean. It's a good idea to clean bat-
tery terminals once a week.
