4-2. RECEIVE
4-2-1. Microprocessor back-up battery
The R-5000 has a rechargeable back-up battery which is
charged automatically while the AC power cable is con-
nected to an AC outlet. It takes about 6 hours to recharge
a deeply discharged battery using the AC power cable. If
you suspect the battery is not charged when you purchase
the R-5000 or the radio performs erratically, perform the
"A = B (reset)" procedure described in section 4-2-2. The
battery will last about 10 days with the AC power cable
disconnected.
4-2-2. Microprocessor reset
When the microprocessor has functioned erroneously or
when installing the transceiver, switch on the power with
the A = B key pressed.
Note:
The microprocessor can be easily reset. However, only
perform this operation when necessary since the contents
of the operated programmed memory are cleared by reset-
ting. It can take a little while to reprogram 100 memory
channels!

vided in the form of a series of audio beeps.
