Alarm: Needs your help lads?

GTS , E Manno and you other reprobates :D

Doing a "M8" a favour and need a manual for a Iplex 4 Channel DVR, seem to be hitting a dead end and cannot find a setting for a "Spot monitor" split screen.
Ponced about with it for a bit but to no avail ( Was not too interested TBH but you do what you do).

Any ideas?

Ta lads
