Roberts Radio Gemini 49 RD-49 - Manual (Page 6)

Using the AC adaptor
The AC adaptor for use with the RD49 should provide 12 volts DC
output at 500mA centre pin positive.
1. Insert the adaptor plug into the DC in socket on the left hand side of
your radio.
2. Plug the adaptor into a standard 13A mains socket outlet. Whenever
the adaptor is plugged in to the radio and switched on at the mains the
batteries are automatically disconnected. If the adaptor is plugged in to
the radio but not switched on then the radio will run from the batteries
if fitted.

4. The charge light will flash indicating batteries are charging. Batteries
will be fully charged in around 7 hours.
• Important: when using rechargeable batteries the battery switch
must be placed in the rechargeable position. Batteries will only
be charged when the radio is switched off and connected to the
AC adaptor.
• Reduced power, distortion and a ‘stuttering’ sound are all signs that
the batteries may need recharging.
• If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
