ESK residents - don't run the risk of missing out on watching the State of Origin tonight.

In Esk, all free-to-air TV channels except the ABC will change frequencies today.

Residents who receive their TV signal from the Esk tower will need to retune after 3.30pm.

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

Retuning is done using the remote. 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.

A video and 3-step guide to retuning is available at retune.digitalready.gov.au.

Viewers might want to write down their favourite channel, program recordings or parental lock settings before they retune.

There may also be outages to TV services over the next two days. Viewers will not need to retune again - the TV services will reappear once the work at the transmission site has been completed.

Viewers can find information about how to retune and any scheduled retune outages on the website or by calling the Digital Ready Information Line on 1800 20 10 13, 8am to 10pm (AEST).

Viewers 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.
