SOME free-to-air TV channels in Wide Bay will soon change frequencies.

A Federal Government spokesman said affected areas included Eidsvold, Bundaberg, Gayndah and Mundubbera.

The move is part of a national retune program that will free up broadcasting spectrum for new services such as mobile broadband.

The date of the retune for each area depended on which tower viewers received their signal from.

The retune will need to be done on October 16, in the Wide Bay after 5am, in Eidsvold after 2.30pm, and in Mundubbera after 3.30pm.

Viewers in Monto may have retuned earlier this year.

However, they may now need to retune again.

Retuning is done using the remote.

For most systems press the "menu" button on the remote.

Look for settings such as "channels" or "auto-tuning" and follow the prompts to retune.

A video and three-step guide to retuning is available on the website www.retune.digital ready.gov.au.

The retune is scheduled to avoid evenings and weekends.

There may be some temporary disruption to all TV services on retune day on October 16.

Service outages on the days before and after the retune may also be necessary, due to work being done at the transmission site.

As the retune simply moves free-to-air TV channels to a new location on the broadcast spectrum, it is unlikely to change TV reception or coverage.
