| If the delay difference is more than 20 us, or gets so large that the ''clkoff'' or ''maserdelay'' values lose precision, run ''fmset'' to get the delays back to something manageable. //Make sure you are not recording while running fmset! Issuing a ''halt'' command from e-RemoteCtrl followed by ''disk_record=off'' is usually a safe method.// | If the delay difference is more than 20 us, or gets so large that the ''clkoff'' or ''maserdelay'' values lose precision, run ''fmset'' to get the delays back to something manageable. //Make sure you are not recording while running fmset!

| If the delay difference is drifting (usually linearly), the DBBC probably needs reconfiguring. This can be done from e-RemoteCtrl as follows (again, best to halt the schedule and make sure you're not recording): | If the delay difference is drifting (usually linearly), the DBBC probably needs reconfiguring.
