When the batteries reach stage 3 shown in the table, the
BATT indication on the WRR-800A/801A/850A/855A also
starts flashing.
Note
The indication may be incorrect if the batteries are not new
when installed. If you plan to use the transmitter for a long
period, it is best to replace the batteries with new ones.
