Helsinki, Nov 9 (DPA) Finnish mobile telephone giant Nokia Monday advised customers to replace certain chargers for mobile phones and other devices made this year over fears of potential electrical shocks.

The chargers were made by a third-party supplier and were to be replaced free of charge, Nokia said, adding it was not aware of any accidents related to the chargers.

In the meantime, customers were advised not to use the chargers.

The models included the AC-3E and AC-3U models, manufactured between June 15 and Aug 9, and the AC-4U model, made between April 13 and Oct 25.
