Troubleshooting Tips:

• Do not plug the clock into a surge suppressor. This will block the alarm and receiver functions.
• Random alarms may occur when the built-in Remote Receiver is turned on. High power electronics and machinery can cause false alarms. If the clock is not used with other signaling equipment, turn the RECEIVER switch to the off position.
• The Sonic Boom clock will not receive signals from signaling equipment that is plugged into a separate electrical circuit or surge supporssors.
