I copied this from a different Clifford system but the programming should be the same.
Digital Dual-Zone Proximity Sensor:
Be aware that the Proximity Sensor uses radar waves to detect movement. These waves pass through nonmetallic materials like
plastic, carpet, glass and wood. However, metal and metallic-colored paint, metallic-colored plastic and even some metallic window
tinting materials will interfere with or completely block the radar waves. As such, it is not unusual that the Proximity Sensor zones
require some adjustment after installation. In some instances, you may need to try a different location for the sensor.
Since any metal objects above or near the Proximity Sensor will have a significant impact on operation, warn your customer never to place coins, CDs, cassettes (due to the ironoxide tape) or other metallic objects above
or near where the sensor is mounted.
1. Turn off any fluorescent lights that may interfere with the sensitivity testing of the radar sensor.
2. Disarm the system with the remote control.
3. Transmit channel 16 on the master remote (LevelShift three times, then button 4). You will hear one chirp and the LED will turn on.
4. Test the Proximity Sensors primary zone by rapidly leaning through an open window into the passenger compartment. You will
hear a siren chirp when the primary zone is triggered. This should not occur near the window, but instead when you would be in a
position to touch the car stereo.
To change the sensitivity of the primary zone, press and release button 2 to increase sensitivity or button 4 to decrease
sensitivity. To rapidly increase or decrease several steps, press and hold the button. For each sensitivity increase, you will hear a
higher and higher pitched confirmation chirp. For each sensitivity decrease, you will hear a lower and lower pitched
confirmation chirp. Two LoudChirps indicate minimum and maximum settings of the 32-step range of settings. You may now
press button 3 to adjust the warning zone, or press button 1 to fully exit the Proximity Sensor adjustment mode (you will hear
3 chirps).
To change the sensitivity of the warning zone, press button 3 (youll hear 1 chirp). Then use the same procedure as above, but
this time, rapidly bring your hands and face to the window as a thief would to see whats inside. The sensitivity of the warning
zone should be set so that it is triggered when your face and hands are within a few inches of the window, no further. When
done, press button 1 to reselect the primary zone (you will hear 2 chirps), then button 1 again to fully exit Proximity Sensor
adjustment mode (you will hear 3 chirps).
5. Repeat the preceding steps as required. An improperly adjusted sensor will cause the system to false alarm or not respond
properly to a genuine threat. Keep in mind that you may need to reposition the sensor, possibly after the customer has had the
system for several days.
