Be sure to observe the cor-
rect polarity.
A built-in step-up convertor in the BP-257 increases the
voltage to 5 V DC.
Approx. 100 mW of output power is possible with the
BP-257 operation. Also, no transmit output power selec-
tion is available.
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
