Metric. The Zone/Cal button provides the selection
to change the compass zone or to calibrate the
compass. The reading lamp buttons also cycle the
reading lamps on or off.
The STEP button (right reading lamp button)
operates a momentary contact switch which pro-
vides input to the Compass/Temp Mirror in one of
the following four modes:
•
To toggle the right reading lamp on and off
upon release of the button.
•
To select degrees in F (Fahrenheit) for the
temperature display.
•
To select degrees in C (Celsius) for the temper-
ature display.
•
To turn off the compass/temperature display.
ENGLISH / METRIC / OFF MODE
With the ignition in the ON position, pressing
and holding the STEP button (right reading lamp
button) for 5-10 seconds will toggle the display
between English and Metric. The Compass/Temp
Mirror stores the selected display mode in memory
upon releasing the button during the 5-10 seconds.
Pressing and holding the STEP button for 10-15
seconds will turn the display OFF upon releasing
the button during the 10-15 seconds.
Each time the temperature mode is changed to F°
or C°, the Compass/Temp Mirror stores the new
mode in memory. The selected English or Metric
mode is recalled after the ignition is cycled. The
display OFF mode is not recalled after the ignition
is cycled. The Compass/Temp Mirror will power up
and display the temperature mode (F° or C°) that
was last selected.
CALIBRATION / ZONE MODE
Refer to the Zone Variance Map. With the ignition
in the ON position, pressing and holding the Zone/
Cal button (left reading lamp button) for 5-10
seconds will illuminate ZONE in the display. Re-
leasing the button while ZONE is illuminated will
enter the compass into the Zone Setting mode. The
Compass/Temp Mirror will illuminate the Zone
Variance number 1 to 15 that is stored in memory.
While ZONE is displayed; momentarily pressing
the Zone/Cal button advances the zone to the next
higher zone. When the desired zone number is
displayed, do not press the Zone/Cal button again.
After 5 seconds, the Zone Variance number will be
stored in the module memory.
With the ignition in the ON position, pressing
and holding the Zone/Cal button for 10-15 seconds
will toggle the CAL (calibration) mode between on
and off. Releasing the button while CAL is dis-
played enters the compass into the calibration
mode. See ‘‘First Time Calibration’’, ‘‘Manual Cali-
bration’’, and ‘‘Continuous Calibration.’’
Pressing and holding the Zone/Cal button for
15-20 seconds and then releasing will exit the CAL
mode and toggle the display to the current state of
compass/temperature mirror use; OFF, Compass/
Temperature F°, or Compass/Temperature C°.
Pressing and holding the Zone/Cal button for
20-25 seconds will enter the CTM into the self-
check diagnostic mode upon releasing the button.
Holding the Zone/Cal button for longer than 25
seconds will cause the display to return to its
current state with no changes.
