Battery operation using alkaline batteries
1. Remove the battery cover on the back of the unit by sliding the cover
in the direction of the arrow.
2. Insert six LR6 (AA size) alkaline batteries into the spaces in the
compartment. Take care to ensure all batteries are inserted with the
correct polarity as shown inside the battery compartment.
3. Slide the battery switch to the
battery cover.
• Important: when using alkaline batteries the battery switch must
be placed in the alkaline position. Failure to do so could result
in serious damage to the batteries or radio.
• Reduced power, distortion and a ‘stuttering’ sound are all signs that
the batteries may need replacing.
• 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.
• We would recommend for economy that the RD-49 is used via the AC
adaptor whenever possible with battery operation for occasional or
stand-by use only. If extended listening using batteries is anticipated,
then the use of rechargeable batteries is recommended.

4. The charge light will ash 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.
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 tted.
The AC adaptor should be disconnected from the mains supply and
the radio when not in use.
