Aerials
As supplied your clock radio is fitted with a telescopic aerial. Should this
prove inconvenient a separate wire aerial can be fitted in place of the
telescopic aerial.
A spanner is provided to allow removal of the telescopic aerial. The wire
aerial can then be plugged in place of the telescopic aerial.
Note : In areas where signals are weak the wire aerial may not
prove to be as effective as the telescopic aerial.
