Default 3300 corvette battery charger question

In the manual

If the US 3300 Corvette ( model 1051) does not switch to maintenance charge mode after three days, manually switch it to pulse maintenance mode

Can't find in the manual how to switch it manually. Unless I am blind and some hidden button somewhere on the charger...

Seems when I hooked it up first time all was fine. Then did some cleaning and set the alarm. Now the charger doesn't go to maintenance mode

There is no switch on the US 3300 Corvette Model 1051 charger. It's a rebranded (and slightly modified) CTEK 3300. Unfortunately, the modifications included removal of a MODE button the CTEK-branded version has. It looks like the Owner's Manual was not updated to reflect the change.

T
he most likely reason why the charger doesn't switch to Maintenance Mode within three days is a worn out battery that should be replaced.

Took it off for 3 days and reattached charger - went to green ( maintenance mode) in about 4 hours.
Sad they make a model with the Corvette name but make it a cheaper version removing some modes
