Ok thanks. In the option menu, the very last option I have is called "Speed Limit" which I can toggle on/off. But I don't think it's the height speed limit cause yours is 5.2 and the one I'm talking about is the last one. (Or maybe they just changed the order). Is this supposed to prevent user from changing the raise speed settings?

Also, in the steering configuration, what's the difference between "steering response", "steering straight" and "steering height speed/low speed" ?

You can't find the service manuals on crowns website, it is something you have to purchase separately unfortunately. The operators manual does not have any info on the features menu.
Here is the feature menu options:

F1: Language
F2: Units of measure (English or metric)
F3: User performance (allow user to switch from P1, P2, or P3)
F4: User login codes (sets login codes for different users, like a less advanced infolink system)
F5.1: Height speed limit on/off
F5.2: Gate Alarm on/off
F5.3: Gate travel on/off (requires the gate to be closed at height)
F5.4: Hand presence on/off
F5.5: Lift limits
F5.6: Sleep Delay (requires rekey once asleep
F5.7: Travel alarm activation
F5.8: Lift alarm activation
F5.9: Strobe light activation
F5.10: Tilt sensor on/off
F5.11: Power load tray on/off

Some of these features should be left enabled for safety and some components like a strobe light or power load tray may not be installed, if enabling any functions that are not installed on the lift it could throw a code. Please be careful when changing settings.

I tried to look on crown website but they just have basic operator manual to download, not service manual.

I just remember that I saw a manual in a tube hidden under the wave. Is this a service manual ? I'm not at work now can't check it. But if it's the case I'll stop looking online and going to wait to be at job hehe

If you get a service manual from crown and not just the operator manual all the settings will be explained in the Access123 section
