Note: The Driveway Monitor's battery life is affected by these sensi-
tivity settings:
Low = 1
½
year battery life
Medium = 1 year battery life
High = 1 year battery life
A weak battery may cause false activations or missed detections. The
C cell Alkaline batteries in the Driveway Monitor sensor must be re-
placed every 1 to 1
½
years, depending on the sensitivity setting.
2. Insufficient Range:
If your Driveway Monitor system works when the driveway sensor is
close to the house but not when the driveway sensor is far away, the
following adjustments may improve the range of the system:
• With the unit on the ground using the stake provided, you may not
get maximum range. Mount the driveway sensor 4-8 feet off the
ground to a tree or post (that will not sway in the wind) to increase
range.
• Move the receiver to a room closer to your driveway. Place the
receiver on a window sill that faces the driveway or on a table close
to the window.
• Move the receiver farther away from computers, CD players, and
cordless phones. These items may interfere with the operation of
your Driveway Monitor system if you place the receiver too close
to them.
• Moving the antenna 45° to the left or right of vertical will sometimes
improve the range of the system.
• An optional long-range antenna is available (see Optional Acces-
sories Section), which gives the system up to double the regular
range.

3. Sensor Learning (do only if receiver does not respond to the
sensor):
There are two ways to teach new sensors to the receiver. The first
adds new sensors to the receiver. Existing sensors will still work with
the receiver. The second procedure erases all learned transmitters
and allows the user to re-teach new sensors to the receiver.

1. Unplug the power supply of the receiver.
2. Wait five seconds and then plug it in again.
3. Wait until the receiver has finished beeping during its powering
up sequence - and the green light goes out for a few seconds
While the green light is still out promptly press and hold the
ALERT light. You should hear a few short beeps. Release the
light.
4. The green power light should flash indicating the receiver is in
code learning mode. You have sixty seconds to learn the code
of the new sensor.
5. Activate the new sensor by rotating the sensor until you hear a
warbling chirp. (If you hear three separate chirps, like a small
bird, the receiver already has that sensor learned in memory).
6. When all sensors have been learned, press the ALERT light
briefly (you should hear several short beeps) and the receiver
resumes normal operation or simply wait an additional 60 sec-
onds and the receiver automatically exits the programming
mode.
1. Unplug the power supply of the receiver.
2. Wait five seconds and then plug it in again.
3. Wait until the receiver has finished beeping during its powering
up sequence - and the green light goes out for a few seconds
While the green light is still out promptly hold down the ALERT
light for about 5 seconds until you hear a steady tone. (When
you release the ALERT light you will hear five more beeps to
indicating that the memory is now empty).
4. The green power light will start to flash indicating the receiver is
in code learning mode. You now have sixty seconds to learn the
code of the new sensor.
