A REMINDER has been issued to Dumbarton and Vale Freeview users that they may need to retune their TVs over the coming weeks to continue watching some programmes.

Some Freeview channels are moving to new airwaves to allow for future development of new mobile broadband services, with transmitters being updated region by region as part of a major engineering programme being carried out between now and 2020.

The main required changes will take place at the Black Hill transmitter group on September 5 and October 3.

On both dates Freeview channels will be off-air overnight until 6am. After this, any viewers who find they are missing channels can retune.

Retuning should be straight-forward and some TV equipment will retune automatically. Some older aerials may need to be replaced to continue receiving all channels.
