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.
Note:
Changes or modifications not expressly approved by the manufacturer could void
the user's authority to operate the equipment.
