1、Sensor Overview
The sensors use a tire pressure monitoring system (TPMS), to form a system
with the car's tire pressure receiving unit, you need to install the tire wheels (as
shown).
2. Instructions for use
In stationary mode, the pressure and acceleration are measured about every 30
second and emission of RF frames occurs only if pressure variation, higher than a
threshold, is detected (leakage detection).
When the vehicle starts moving, the Tire Guard transmitter enters the driving
mode. Then the wheel unit measures and transmits data every 60 seconds.
If, during any measurement period in driving mode, the pressure leakage is
detected (difference compared to the last transmitted pressure value), a alarm
signal will occur taking in account the latest pressure value emitted as reference
value. If the pressure continues changing, an additional transmission will be sent.

4. Warning 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 a particular 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 or
more of the following measures:
-- 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.
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.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
