Message Safe Mode taken is displayed and prompt changes to reflect that session is now in safe mode. All configuration changes that are made (also from other login sessions), while router is in safe mode, are automatically undone if safe mode session terminates abnormally. You can see all such changes that will be automatically undone tagged with an F flag in system history:

[admin@MikroTik] ip route> 
[Safe Mode taken] 

...

[admin@MikroTik] ip route<SAFE> add 
[admin@MikroTik] ip route<SAFE> /system history print 
Flags: U - undoable, R - redoable, F -

Now, if telnet connection (or winbox terminal) is cut, then after a while (TCP timeout is 9 minutes) all changes that were made while in safe mode will be undone. Exiting session by [Ctrl]+[D] also undoes all safe mode changes, while /quit does not.

If another user tries to enter safe mode, he's given following message:

[admin@MikroTik] >
