1. Warning
1.1 Federal Communication Commission Interference Statement:
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in an installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one of the following measures:
01
English
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

1.2.1
Do not operate a TPMS receiver while driving. The company is exempt from all consequences because
of driver’s careless and improper operation.
1.2.2
The system adopts the wireless transmission of signals. In some special circumstances, interference or
erroneous methods of operation or installation method errors may cause weaker signal or its inability to
receive signals. If the insulation adhesive sticker of the windshield contains metal material, it will be likely
to affect reception conditions.If the tire pressure and temperature readings on the TPMS receiver are
displayed as “---”, this condition represents the receiver cannot receive signals emitted by the sensors.
Drive the vehicle away from the current location (nearby there may be signal interference) or drive the
vehicle to a tire shop to check.
1.2 Product Warning
02
English
1.2.4
Temporary resealing or re-inflation products containing internal sealants or propellants in any tire
assembly may adversely affect the operation of the sensor/transmitter. The product manufacturer does
not assume any liability as a result of these.
1.2.5
Do not leave the sensors in contact with chemicals, it may cause the sensors to fail.
1.2.3
If the battery status of the TPMS sensors inside the tire is low (because abnormal conditions continue to
occur, the battery may make the TPMS sensors continuously emit signals to warn the driver, so that
battery life is shorter than the normal life), Please go as soon as possible to the specified service stations
to confirm whether the TPMS Sensors need to be replaced.

<IMPORTANT 1>
There is a wheel orientation mark on the surface of the sensor (see Fig 1), please
install the sensors on the corresponding wheels (see Fig 2) on the trailer. If sensors
are properly installed according to the corresponding wheels in Fig 2, then “8.5
Setting the Tire Position on the Receiver” can be skipped during the first installation
and save time.
