Chirping
When chirping begins during the next Day cycle, you can temporarily 
silence End of Unit Life or Network Error chirps by pressing the 
Test/Hush button. Low Battery chirps cannot be silenced. If a valid 
Night / Day cycle has not been established because the unit is located 
in either a constantly dark or lighted location, the chirps mentioned above will not be delayed at night. Moving the unit 
to a different location might allow the unit to determine a valid Night / Day cycle.
 WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE OR LOW BATTERY MODE. 
POSSIBLE CHIRPING REASONS
End of Unit Life: will be delayed at night
Network Error: will be delayed at night
Low battery: will be delayed at night
