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.

may switch off after ashing only briey. This may happen if the batteries are
already freshly charged, or if the radio detects that you may be attempting to
recharge alkaline batteries. In these cases the charging will be stopped.
4 When charging is completed the charging indicator will show a steady green
and a green ‘Battery Full’ indicator will be displayed. If the charge process stops
after a short while this may be due to a faulty battery. In this case the charging
