Yale,

Sounds like you have telemetry installed on this lift. That small screen on the left side is used for the operator to login. First, turn key on, press brake pedal and see if lift starts up, if not try pressing horn button after turning on. If you still have issues, need to check with the company you purchased it from, they need to give you a card or password. If you still have problems, let me know as I have a way to jump out telemetry. Good Luck.
