hi

i had been using one unit of mitras simu stick 55 and connected it to L3,L4 socket.

i set this to illumination 4 with auto-switch on timer from 4pm to 12pm

recently i purchased an additional unit of mitras simu stick 55, and i plugged the 2nd unit to port 2 of the mitras driver.

however the auto-timer no longer works, and the lamp is always-on for 24 hours per day

pls help.
