Topfield 5800/Troubleshooting/Recording Interruption
Reference material by Wikibooks contributors. This retains its source identity and is not 411 news reporting.
The Toppy only has two tuners, so it is sometimes necessary to alter one of the tuners in order to start a second recording. This will interrupt viewing with a "CYR" prompt, giving the user a choice to cancel the recording instead.
However, there is a bug in the system which means that the CYR prompt happens at unnecessary times. The [Xw] WatchNoCYR firmware patch fixes this problem.
