MOUNTING
• For best results mount the outside sensor probe either under the front bumper or in the front door
frame 2 inches under the hinge.
• Mount the inside unit away from electronics, speakers, major magnetic infl uences and out of the sun.
• Do not mount the unit on or near an airbag compartment. Mount the unit horizontally on a
convenient position on the dashboard. Ensure that the chosen position does not interfere with the
driver’s view of the road.
• Clean the mounting surface, peel and apply the hook & loop tape on the base of the compass.
• Tilt the compass display for optimal visibility. The compass will only get an accurate reading when it is
placed horizontal. (Note: The display panel should be made from 70° to nearly vertical to horizontal plane
for obtaining optimal sensitivity. The screen should be straight up and straight across when mounted.)
CALIBRATION
• Find a location where it will be safe to make a U-turn (an empty parking lot is ideal) for your vehicle.
Park the vehicle away from other vehicles, leaving the engine running. Switch on all electrical
accessories that are normally used (heating fan, radio, etc.).
• Make sure the compass is fi xed tightly on your dashboard. Press and hold the reset button for 3
seconds (cardinal points, numeric digits and the word “CAL” will fl ash); wait for 5 seconds to avoid
initial, unstable condition, then immediately begin driving the vehicle slowly in a circle.
• Complete at least one full 360˚ circle while the fl ashing “CAL” is displayed. After approximately
10 seconds the fl ashing “CAL” will disappear and the cardinal points and the numeric digits will
stop fl ashing.
The calibration of the compass is now completed. Check that the compass is providing readings that appear to be correct.
USING THE COMPASS
• When switched on, the circuitry of the compass continuously scans the magnetic fi eld in the vehicle.
This can cause the display to fl uctuate even when the vehicle is stationary.
• The compass will only get an accurate reading when it places horizontal. (Note: The display panel
should be made from 70˚ to nearly vertical to horizontal plane for obtaining optimal sensitivity.).
• The magnetic fi eld produced by the use of any electrical equipment that was not in use during the
calibration sequence (windshield wipers, rear window defroster, etc.) may cause temporary errors in the
compass reading.
OPERATING INSTRUCTIONS
• THERMOMETERS
• IN/OUT TEMPERATURE
It shows the In/Out temperature at the same time.
• FREEZE ALERT
To activate FREEZE ALERT slide to “ALARM” to
alert you by both beep alarm and fl ashing LED’s
when the road is slippery due to black ice effect.
An “ALERT” sign will appear beside the temperature
readout on the display. Slide to “LED” to alert you
only by fl ashing LED’s when the road is slippery due
to black ice effect. An “ALERT” sign will appear
beside the temperature readout on the display.
• VOLTAGE METER
Digital Readout: It will show the actual voltage
of your car battery.
• SWITCH CELSIUS TO FAHRENHEIT
The switch to change from Celsius to
Fahrenheit is in the battery compartment
under the battery. To turn off FREEZE ALERT:
slide to ALERT OFF. Freeze Alert Intermittent
Flashing LED Lights and/or Beep Alarm per
minute.
• LED INDICATORS
These easy-to-read indicators help you
understand the car battery condition at a
glance.
• BATTERY METER
The LED indicators tell you the car battery
condition.
