WARNING

Failure to observe the following warning items may result in serious traffic accident due to tire damage or detection
of erroneous

• Install or uninstall the sensor at a tire shop.

• Refer to the instructions in the operation guide when installing or uninstalling the sensor.

• Use genuine mounting band to secure the sensor. Using unauthorized band can cause the band to break during
vehicle movement resulting in rim or tire damage.

• Be sure to use new mounting band matching the wheel diameter and rim size. Using mounting band that is too
long, too short, or previously used can cause the sensor or band to drop out during vehicle movement resulting in
rim or tire damage.

• If the width of the well at the center of the rim is extremely narrow causing the sensor to touch the wall of the well
or if the well is extremely shallow causing the sensor to protrude from the well, contact your authorized dealer or
Bridgestone customer service and check that the sensor can be installed beforehand.

• Be sure to attach a white plastic "valve mark" on the valve of the tire with sensor installed.

• Be careful not to damage the sensor or the mounting band when replacing the tire. The mounting band can become
loose and drop out during motion when it comes in contact with tire lever or tire changer. Tires with white plastic
"valve mark" on the valve are tires with sensor installed near the valve. Be careful with their handling.

• Normal "mounting tire on rim" and "removing tire from rim" involves equipment such as tire changer and can cause
tire damage. Observe the general precautions for "mounting tire on rim" and "de-mounting tire on rim" described in
the equipment manual.

• If the tire is improperly rimmed, the tire can burst and fly apart when inflating. Be sure to inflate the tire inside a
safety enclosure.

• This guide describes the precautions during installation of this product, but it is not possible to assume and
describe all hazards. Be very careful when performing these tasks.

Sensor Transportation,
Storage, and Disposal

The sensor periodically transmits radio waves (periodic transmission function). Therefore, you must stop the periodic
radio wave transmission function when transporting, storing, or disposing the sensor.

4-1 Precaution during transportation



Sensor used as Hand Reader type

Sensor used as Hand Reader type will not transmit radio signals unless instructed by the hand reader. It has no
periodic transmission function so it can be transported without any problem.



Sensor used as On-Board type

Sensor used as On-Board type is set to "Normal transmission mode" and periodically outputs radio waves.

When transporting sensor by air

Stop the periodic transmission using a separately purchased hand reader so that the radio waves from the sensor do
not interfere with the electronic equipment on the airplane. Refer to the "On-Board Type Operation Guide" for
information on how to set with the hand reader.

4-2 Precaution during storage

Both the Hand Reader type and On-Board type sensor must be placed in a sealed metal box when storing to shield them
from hand reader signals and 125 kHz frequency radio signals (output by some types of inverter, IC card reader, or ID
card reader).

NOTE

• When storing for an extended period, stop the periodic transmission of sensor used as On-Board type.

4-3 Precaution during disposal

Your purchasing dealer will salvage the sensor you no longer need. Contact your dealer when disposing the sensor.

become loose and dropped. Remove the rim and check the sensor. If
the sensor is damaged, replace it with a new one.

Position the hand reader antenna at several spots around the tire and
measure.
If there is a response at position not near the valve, remove the rim
and tighten the mounting band once more.

Remove the rim and check the sensor.
If the sensor is damaged, replace it with a new one.

• Check the measurement procedure once more and check whether
measurement cannot be obtained with any tire.

• The battery of the hand reader may be low. Replace it with a new
one.

If still there is no response, ask the dealer where you purchased it.

If other sensors respond but a specific sensor does not, remove the
