setting mode.
FRONT TIRE-Low Tire Pressure Setting Mode
When the tire is under non-deflate condition, the pressure will increase and decrease simultaneously
with the temperature, normally, there will be 1psi (7kPa) when the temperature got difference of 10℉
(6℃), and this is normal physics phenomenon. ORO TEK suggest to the user , when is checking on tire
pressure, its important to keep the tire pressure under suitable pressure, the Low tire pressure unit will be
recognized as warning unit, however, when the pressure is higher than 25% from the cold tire unit, the
system will start the alarming.

psi), if do not to modify anything, then press the
Set Up buton for enter next setting mode.
NOTE: If the pressure unit is kPa the display will
show 230 and 32 for Psi by flasing

once, the low
tire pressure value will add 1 unit; and the unit
value will add 0.1 bar by each press, when it has
reached 2.8 bar the system unit will return to 19
bar.
NOTE: If the user is settee by kPa, will add 10
kPa by each pressing, the range for kPa is
190kPa~280kPa, and 27 psi ~ 40 psi for PSI
unit.
