3. Operation to Change Unit of Tire Pressure and Temperature
W401 displays 3 kinds of pressure units, bar, kPa and psi. For temperature,
O
C,
O
F are the
units displayed. The factory default for pressure unit is psi, the user can change the pressure
unit by pressing the MODE button for 3 sec., and the factory default for temperature is
O
C
,
the user can change the temperature unit by pressing MODE button for 3 sec.
4. Operation to Modify Factory Default
W401 has 4 factory default modes for users to choose from. Press the SET button continuously
for 3 sec. to enter the set up mode from Front tire-Std. tire pressure set up, Rear Tire-Std.
tire pressure set up, Tire Temperature-Over Temperature Warning, Operation Mode and for
other parameter settings, please refer below for the relevant process:
NOTE: The user should change the suitable pressure unit for own vehicle before entering
into the setup mode.
FRONT TIRE-Standard Cold Tire Pressure Setting Mode
When the tire is under normal inflated condition, the pressure will increase and decrease
simultaneously with the temperature, normally, there will be 1psi (7kPa) fluctuation when the
temperature differs about 10
O
F (6
O
C), and this is normal physics phenomenon. ORO suggests
that, when checking on tire pressure, it’s important to keep the tire pressure under suggested
specifications, the Cold & Low tire pressure setting will be recognized as a warning, however,
when the pressure is higher or lower than 25% from the cold tire pressure setting value, the
system will notify to the driver.
Warning: Standard Cold Tire Pressure setting value, please check on each vehicle’s user
manual.

Pressing the SET button for over 3 seconds
to enter the Front Tire-Standard Cold Tire
Pressure Setting Mode.
b
The wireless receiver and display unit shows
the standard cold tire pressure. The factory
default value (35psi) is shown in blue and the
yellow light indicates the ”psi”. or pre-selected
units ( kPa or bar). If no modification is needed,
press the SET button to enter the next setup
mode
.
NOTE: If the pressure unit is in ”kPa” the
display will flash 250 and 2.5 for ”bar”.
