TK SB III SR+ uP-IV controller how to access super guarded access

Hi anyone knows how to access the superguarded access of uP -IV controller to activate the service alarms? I have pressed the TK logo for three seconds but it doesn't show up the guarded access mode. I have tried it when the engine is not running the only thing appeared is Pre Trip.

Hi

you can press TK and Clear bottom togather at the same time to 10 seconds . then you will be at gurded accsses . then press select key to transmit from place to another .

Unit on, not running, all alarms cleared (if possible) continuous run selected.
Press TK & Clear and hold until the unit enters Guarded Access (hour meters).
Press mode (circle) repeatedly until you reach Ddur.
Press TK & Clear and hold until the unit enters Super Guarded Access (CRA)
Press mode to scroll further through the menu.
