If your console is chirping, it generally means that one of the Littlelites is shorting out. This will cause too much current to be drawn from the power supply to the Littlelite circuitry. Remove one or both of the Littlelites and reboot the console. If the problem stops, replace or repair the Littlelite that caused the problem. [ETC Part# M703]
Reminder to not use HI intensity Littlelites.
If this does not fix the problem, the power supply was damaged due to the short, and you should replace the power supply.
