Auto retune and associated messages
A signal is sent out by the broadcaster when
channels change or new ones are available.
Auto retune (assisted retune) picks up this
signal and automatically scans for new
channels. This can happen at any time and
may happen more than once during the digital
switchover. You can adjust this so the retune
starts with or without your permission.
In the channel set-up menu
Select ‘Auto retune’.
Use [t] and [u] to change the auto
retune settings.
Press [OK] to accept.
Always ask – a ‘confirm retune screen’
will appear before a retune.
Always start – retune starts
automatically, warning you during the
retune.

information, not needing a retune.
Adjusting the auto retune messages

retune messages settings.

‘major’ messages.
