BBC Olympics on Freeview

The BBC has begun re-configuring its services on Freeview ahead of the 2016 Olympics, which start in Rio next week.
Ahead of changes to three of its regular HD channels, which are due to occur on 27th July, additional Red Button streams are now available to around 70-75% of UK households and found between channels 602 and 608.  Viewers will require DVB-T2 compliant equipment (Freeview HD, Freeview Play, YouView, EE TV) to view.

The changes to BBC services on Freeview are as follows:

On Wednesday, BBC Four HD is will to move to the channel currently occupied by CBBC HD until just after the Olympics.
A temporary CBBC HD channel will broadcast on channel 97. Like the BBC Red Button channels on 602-608 and 114, the temporary service has reduced coverage.
If you are already able to receive BBC News HD on Freeview 107, then you can receive the temporary CBBC HD channel, otherwise you will only receive CBBC in standard definition on 120 until after the Rio Olympics.

CBeebies HD is also due to change broadcast slots on this date, although coverage remains the same.

Retuning
Viewers who only have standard definition Freeview do not need to retune, providing you have BBC RB 0 on channel 600. All other changes are limited to services only visible on HD compatible receivers.
Some channels are changing frequency, so some TVs and receivers may need retuning to restore BBC Four HD, CBBC HD (which will be on a temporary channel – 97 – until after the Olympics), CBeebies HD, BBC RB2 and BBC RB3. Series links will be broken, remember to reset them.
