when on the buses a spreadover was when you got a big ■■■■ off break in the middle of the shift like 3 hours. That was sleeping bag in the boot time lol
Mr B:
my hour guard wouldn’t allow me to start until i’d taken 11 hours.
Was the timer on Break for the full duration of at least 3 hrs?
If Yes then:
Whats the Serial Number of the Hour Guard? It can be found on the corner of the box it came in or under the battery in the battery compartment, but plug it into charge before removing the battery 
If I think rightly off hand DHG’s with a serial number of 01-0001 to 01-1000 and 02-0001 to 02-01000 didn’t have the split shift programmed into the software I’d happily replace it with the latest version of software which does handle the Split Shift
The actual serial number is the last 6 digits on the barcode starting 2008 xxxxxx
