Powering Up the Unit
• Plug the transformer in to the power outlet and ensure the supply is switched on.
• The unit should now power up. If not, unplug the unit and check all wiring.
• The buzzer on the control unit should sound for 1 second.
Check the LCD display.
If the display reads “LCD CONTRAST (0-9):[0] #=DONE the unit is OK.
• If the unit does not get to this stage, or displays a different message, check that the cable between the head
unit and control unit has been wired correctly.
