Was trying to put unit on stand by and ending up locking display. Now I can't unlock.

Is a 2001 Leisure Bay Spa> Digital control, says Xtreme-tech and Genius
on top.

Also, what exactly are the two buttons to push to put on stand by? If I knew this, I wouldn't have accidently locked it.

it would have been nice to have been given a manual on how to work this thing.

Most systems require that you push and hold the up and down temp arrows to unlock the system, when you hold on the buttons the display should change to show the lock/standby setting that it is currently on, the up arrow will change whatever it is set for and your all done. To simply get the spa running back like normal without doing that all you should have to do is cut the power for 20+minutes.

Not sure how to unlock, but standby:

Just hit one of the temp up/down arrows, then in less than 2 seconds, hit the light button. Presto
