Installing the SEFD1 Batteries
The SEFD1 requires two (2) AAA alkaline batteries.
Always use fresh batteries of the
required size and recommended type, and follow all instructions for properly installing
them.
First, remove the battery cover from the side of the unit. Place your finger on the ridged
end of the cover and slide it down.
Next, remove and discard the old batteries.
Install the fresh batteries, paying close attention to the polarity of the batteries. The back
of the unit shows the polarity positions (+ and -) for the batteries.
If the batteries are not installed in the correct positions, the unit will not function
properly.
Replace the battery cover. Insert the square end of the cover in the track and slide the
cover upward using moderate force. Be sure the cover latches into place.
The LED on the front of the unit comes on for approximately ten (10) seconds after the
batteries are installed, indicating that the device has power.
Test the operation of the device by pressing the help button. The monitoring center should
receive the alert, so be sure to call and report that you were testing the unit after changing
the batteries.
Cleaning the SEFD1
If the SEFD1 needs cleaning, use a damp cloth to wipe the unit. You may want to turn off
the power to the base station to prevent transmitting a false alarm if you press the help
button or drop the unit during cleaning. Be sure to turn the power back on at the base
station after the unit is cleaned.
