Power Sources

This system is designed to operate on 8 “C” batteries, not included, or on normal 120V 60Hz AC house current. Attempting to operate this system on any other power source may cause damage to the unit, and such damage is not covered by your warranty.

AC Operation

Insert the small female plug of the AC power cord into the AC socket on the back panel. The plug can only be inserted one way.

Insert the AC plug into your normal 120V 60Hz AC household outlet.

The display will show “AM 12:00”. The display backlighting will turn on for a few seconds and then turn off again.

NOTE: The system has a polarized AC plug with one wide blade and one narrow blade. The plug will only fit into matching polarized AC outlets.

This is a safety feature to reduce the possibility of electric shock. If the plug will not fit in your AC outlet, you probably have an outdated non- polarized outlet. You should have your outdated outlet changed by a qualified, licensed electrician. Do not file the wide blade on the plug, or use an adapter to make the plug fit into your outlet. This defeats the safety feature and could expose you to electric shock.
