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, it’s important to keep the tire pressure under suitable pressure, the Low tire pressure unit will be

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.
