- Be careful not to touch the antenna against metal such as wheels. Otherwise, radio waves
from the sensor will be blocked and data transmission will fail.

- If you want to measure the inside dual-tire, insert the antenna through a decorative hole in
the outside wheel and press the antenna gently against the inside tire’s side wall near the
valve. If the sensors are correctly installed on the wheels as described in the Sensor Users
Manual, the inside-tire valve is located diagonally opposite from the outside-tire valve.

- Data measurement starts when the MEASURE button is released.

- Data measurement takes place only once after the button is released. Pressing and holding

the button again will have no influence.

④ Data are sent from the sensor on the tire to the hand-held reader.

⑤ When data transmission is completed, a short beep sounds twice and the received data are

displayed on the LCD.

If data transmission is not successful, a long beep sounds and the “try” (data reception error)
message is displayed on the LCD. Press the MEASURE button again to measure data while
ensuring that:

- The tip of the antenna is away from the wheel and other metal parts.

- The tip of the antenna is placed as close to the valve as possible.

- The antenna is placed as perpendicularly as possible relative to the tire’s side wall.
