SECTION 2
DRIVING YOUR MOTOR HOME
2. Press the °F/°C button to toggle between dis-
playing °C and °F.
3. If the unit has been properly calibrated, the
heading will remain 'on' continuously. If the
unit does not have a valid calibration, the
heading and the word 'CAL' will flash con-
tinuously.
4. If the temperature reading is valid, the tem-
perature display will remain 'on' continu-
ously. If the temperature reading is invalid
(due to an open or shorted temperature sen-
sor), the temperature reading will flash con-
tinuously.
5. Unit goes to SLEEP MODE when ignition is
turned off.
Sleep Mode Operation:
1. Unit enters SLEEP MODE when ignition is
turned off.
2. The display is blank and the unit is in a LOW
POWER MODE.
3. Unit wakes from SLEEP MODE and enters:
A. Ignition ON operation when the ignition
is turned on, or
B. CAMPING MODE when the °F/°C or
the MODE button is pressed for three (3)
seconds.
Camping Mode Operation:
1. Unit enters CAMPING MODE after the °F/
°C button or MODE is pressed for (three) 3
seconds while in SLEEP MODE.
2. Unit displays temperature and heading for
ten (10) seconds; the display stays 'on' if
you continue to push either button and then
returns to SLEEP MODE ten (10) seconds
after the last button was pushed.
Nighttime Dimming:
The display brightness is lowered by 50%
when the vehicle headlights are turned on.
Calibration:
NOTE: The calibration procedure requires you
to drive your coach in a circle during
calibration mode, so you will need to be
in a large area clear of obstacles, such as
a vacant section of a parking lot.
2-14
The compass must be calibrated after its ini-
tial installation and anytime the compass sensor
is replaced or relocated. The calibration values
are saved in EPROM memory, so it is not neces-
sary to recalibrate if the battery is disconnected.
Calibration Procedure:
(Best performed in empty parking lot)
1. Press and hold the MODE button until the
words 'ZONE' and 'CAL' appear (approxi-
mately ten (10) seconds). The unit will dis-
play the current zone value.
2. Press the °F/°C button to increment the zone
value.
3. Press the MODE button to store the zone
value.
4. The unit now displays the word 'CAL'. Press
the °F/°C button to enter the calibration
mode. The display will begin counting down
from 60 seconds and the work 'CAL' will
flash. Drive slowly in a circle during the 60
second calibration period. If the calibration
procedure fails, the unit will flash the word
'CAL' continuously. If the calibration proce-
dure is successful, the unit will display the
work 'CAL' for five (5) seconds and then
return to normal ignition 'on' operation.
ICE WARNING
The ICE feature is designed to alert the driver
when ice may be present on the road. The feature
works as follows: When the temperature transi-
tions from above 40° F to below 37° F, the ICE
feature is enabled. The ICE feature loops through
the following displays for 1 minute; "ICE" for 2
seconds, "outside temperature" for 2 seconds.
After the 1 minute timeout expires, the ICE fea-
ture is disabled, and the unit returns to displaying
the outside temperature. The ICE feature remains
disabled until the temperature climbs above 40°
F. The ICE feature only works in ignition on
mode. The feature is not present in camping
mode. For the ICE feature to be enabled, the out-
side temperature must be above 40° F. If the tem-
perature is below 40° F when ignition is turned
on, it is assumed that the driver is already aware
of the cold temperature.
