Using an AC adaptor (not included)
The AC adaptor for use with the R9921 should provide
6 volts DC output at 300mA centre pin negative
(Roberts type PU6-B).
Insert the adaptor plug into the DC socket (18) on the
left side of the radio. Plug the adaptor into a standard
13A mains socket outlet. Whenever the adaptor is
used the batteries are automatically disconnected.
The AC adaptor should be disconnected from the
mains supply when not in use.
We would recommend for economy that the R9921
be used via an AC adaptor whenever possible with
battery operation for occasional or stand-by use
only.
