Residents receiving digital service from Warrnambool's TV tower will need to retune to access free-to-air channels after stations move to new frequencies today.

The adjustment will free up broadcasting spectrum, allowing room for new digital services such as mobile broadband.

Once the channels have moved about 3.30pm, viewers will need to retune their digital TV, set-top box or digital TV recorder to get them back.

For most systems, viewers should press the ‘menu’ button on the remote, look for settings such as ‘channels’ or ‘auto-tuning’, then follow the prompts to retune. 

Videos and a three-step guide to retuning can be easily found online.

There may be some disruption to all TV services for several hours today due to work being conducted at the transmission site. 

There may also be outages to all TV services until Wednesday. 

Viewers will not need to retune again – the TV services will reappear once the work at the transmission site has been completed.

Viewers who are having difficulty retuning their equipment should check their manufacturer’s handbook or manual for instructions on how to retune, ask a friend or family member to help, visit the retune website, or call the Digital Ready Information Line on 1800 20 10 13, 8am to 10pm.
