Error Messages
If an error occurs in the detector, the corresponding error message will be displayed on the
LCD, the unit will beep, and the alarm light will blink yellow. (The unit will give two beeps
instead of beeping constantly, if a device error occurs when the audio level is set to MUTE.)
The table below lists the major error messages. If an error occurs, check the cause of the
error and take necessary actions. When no error message is displayed but the button or
display does not function, remove the batteries, reinstall them, and turn the unit on again. If
the unit does not reset to normal, contact New Cosmos or your New Cosmos representative
for repair.
