Mail AlertTM
Congratulations on your purchase of Mail AlertW.
Mail AlertTM tells you when the mail is delivered. It works from up to up to 500’ feel away, line of sight.
Parts Included: Mail AlertTM Transmitter for mail box
Mail AlertWI Receiver for inside house
12 Volt Ac Wall Adapter
Double Stick Foam Tape for Transmitter
Directions:
1. Plug the AC adapter into both Mail Alert“1 and the wall outlet. The red power light will come on.
2. Test the system before mounting the transmitter in the mailbox. Lay the transmitter with the label
facing up for 10 seconds, then turn it over so it is face up. The Mail Alert“ receiver should beep
several times. If the receiver does not beep, see the Troubleshooting section of the instruction.
3 Mount the transmitter in the mailbox using the double stick tape provided. Mount the transmitter by
peeling one side of the tape off and placing it on the transmitter label. Then peel the other side of the
tape off and mount it on the mailbox according to the pictures below. The arrows on the label should
be pointing up when the mail box door is closed.
4. The receiver will beep every 5 minutes for the next two hours and the green light will flash constantly
until the unit is reset.
5. After the mail has been retrieved, press the red button to reset Mail Alertm.
Volume Control:
0 To lower the volume of the beeper, move the Volume Control Switch (the switch farthest from the
antenna) away from the antenna. SWitching it back increases the volume.
. If the Mail Alert receiver does not respond to your transmitter and it is not a range problem -
use the following 5 steps to teach the receiver the transmitter’s code:
1. Lay the transmitter with label side facing up for 10 seconds.
2. Slide the switch closest to the antenna towards the antenna (learn mode). The green light will burn
steadily.
3. Turn the Mail AlertTM transmitter face up. Or open the mailbox door if the transmitter is already
mounted.
4, The receiver will chirp several times.
5. Slide the Switch away from the antenna (use mode). The green light will go out. Flip the
transmitter label up for ten seconds and then down. The receiver should beep five times. Leave
the switch in this position for normal use.

CIRCUIT DESCRIPTION
The Motion Alert consists of a microcontroller which interrogates
a magnetometer (L2, Q2, Q3) at regular intervals, ranging by
application from 0.25 to 2 seconds apart. The magnetometer is
sensitive enough to detect small changes in the value of the
Earth’s magnetic field projected along its axis. when the Motion
alert is rotated around any of its major axes, the axis of the
sensor will change, typically resulting in a change of projected
field. If the change is large enough, an movement event is
sensed. The size of change needed to trigger an event is set by
software and by option jumpers.
When a movement event occurs, the microcontroller determines
whether to send an alarm. If this is the first event in a long
while, the unit will send a cluster if identical transmissions
identifying the unit to the receiver. If an alarm has already
been sent less than four seconds previously, or if this is one of
a string of closely spaced events, no transmission will occur.
The microcontroller, PIC12C508, keys Q1 in a saw resonator cir—
cuit with L1 as the radiating loop.
