Product Introduction
Thanks for choosing Tyre Pilot TPMS product.The system is used to monitor the
pressure and temperature of each tyre. Once the pressure and temperate parameters
have been set by the user, the system will alarm if abnormal pressure and temperature
are detected and alert the driver.The system should also improve fuel efficiency,
prolong tyre life and make driving more comfortable. Please read the user guide
carefully before installation and retain the manual for future reference.
Safety caution
It is highly recommended that you read the instructions before installing the system:
1. The monitor should be installed inside the vehicle where it does not affect
driving visibility or impede vehicle controls.
2. The vehicle should be stopped and the tyres allowed to cool down, if there is a
high temperature alarm this will avoid potential braking problems or tyre blowout.
3. Driver should stop the vehicle and check the tyre if there is high pressure or
slow leakage alarm .
4. There is a danger of tyre blowout when the tyre pressure is too high, and both
fuel consumption and wheel balance can be affected by high pressure.
5. The system can effectively monitor tyre pressure and temperature BUT it is
not a replacement for vigilance, tyres should still be checked periodically with
an appropriate tyre pressure gauge.
6. It is not recommended that you check tyre data whilst driving.
7. Any adjustment to the parameters should be performed when the vehicle is
stationary and the parking brake applied.

Installation tips
1. The signal between the monitor and sensors is wireless, and the transmission
distance is adequate for a passenger car due to internal anti-inference circuit
design.
2. Due to air expansion and contraction, the tyre pressure and temperature will
continually change whilst driving.
3. If the vehicle is not used for prolonged periods of time natural leakage between
the rim and the tyre will occur. This is not a fault with the sensors.
4. Should you have any question or problem during the installation, please contact
your local distributor.

Installation Instruction
Monitor Display Installation
The LCD display is deigned to utilise the
cigarette lighter adaptor (CLA) power for
a simple installation. Please plug the
display firmly into the cigarette lighter
socket to begin using the STP 1400.
Setting the parameters
Pressure Unit Selection
Selection of pressure unit (PSI or Bar) can be done by user, details as below:
With the vehicle stationary and the STP1400 connected to the cigarette lighter socket.
Press an hold the SET button for 3 seconds to enter the setup mode, the unit will
emit a beep and either Bar or PSI will begin to flash – to change from Bar and PSI or
visa versa press the SET button.
Once you have selected the unit of pressure press and hold the SET button for
two seconds to save and exit the set up or move on to setting the upper and lower
pressure alarms – refer to High/Low Pressure Alarm Level Setting press the SET
button for 1 second..
If the SET button is not pressed for two minutes the unit will automatically exit the
setup mode.

High/Low Pressure Alarm Level Setting
With the vehicle stationary and the STP1400 connected to the cigarette lighter socket.
Press and hold the SET button for 3 seconds to enter the setup mode, a beep will
be heard and Bar or PSI will begin to flash.
Press the SET button again for 1 second and UP will be displayed and a value,
below, will flash – press the SET button to change the pressure setting.
NOTE: This setting is MAXIMUM pressure.Once you have reached the correct
press setting press the SET button to set the LOW pressure and dO will be
displayed, press the SET button to change the value.
To exit the setup mode press an hold the SET button for 2 seconds or to set the
temperature alarm press the SET button for 1 second – refer to Temperature
Alarm Level Setting for details.
If the SET button is not pressed for two minutes the unit will automatically exit the
setup mode.
Temperature Alarm Level Setting
With the vehicle stationary and the STP1400 connected to the cigar lighter socket.
Press an hold the SET button for 3 seconds to enter the setup mode, the unit will
emit a beep and either Bar or PSI will begin to flash, press the SET button 3 times
until UP and oC is displayed.
Press the set button to change the HIGH temperature alarm value .

Important Notice
Purchasers of this product should not solely rely on this tyre pressure
monitoring system for safety and should check the condition and
pressure of their vehicles tyres on a regular basis as described by
the manufacturer of the vehicle or tyre manufacturer. Please note,
Snooper Tyre Pilot System operates on an RF system, as with many
RF tyre systems this system can occasionally suffer from interference
depending on the systems location; thus causing the system to be
inaccurate or not operate at all.Tyre pressures and temperatures are
not the only things that can affect tyre safety; we suggest daily visual
inspections and periodic checks of the vehicle tyres.

Monitor Parameter Display
The display can show current tyre pressure and temperature.
By default the unit will display the current tyre pressures, to view the temperature
press the SET button and the temperature will be displayed for 10 seconds before
the unit reverts back to displaying the tyre pressures.
Alarm Status
High Pressure/Low Pressure/High Temperature/Fast Leakage/Sensor Low
Battery Alarm
The user interface will monitor the pressure and temperature of 4 tyres simultaneously.
When the low pressure value is exceeded display will indicate corresponding alarm
icon ( , ) and the unit will beep.Press SET once will stop the alarm sound , the
flashing icon can only be stopped when tyre problem is resolved.
Factory default alarm setting:
Step to restore factory default setting: press and hold SET key and plug the
console into the cigarette lighter power socket until Bi... sound to confirm factory
setting was restored.

High Temperature Alarm level 70 °C
High Pressure Alarm
e.g.Left Front tyre pressure reached 3.1Bar, display showing alarm with
(Bi…Bi…Bi…) sound as shown.
Low Pressure Alarm
e.g.Left Front Tyre pressure reached 1.9 Bar, display showing alarm with
(Bi…Bi…Bi…) sound as shown.
High Temperature Alarm

(Bi…Bi…Bi…) sound as shown.
Fast Leakage Alarm
If a fast leak is detected the icon, on the display, will begin to flash and the alarm
beep will sound.
To silence the alarm press the SET button, the flashing icon can only be stopped
once the fast leak is resolved.
e.g.Left Front tyre pressure dropped from 2.4 Bar to 2.1 Bar, fast leakage display
as shown.

Sensor Low Voltage Alarm
If one of the sensors battery becomes discharged it will send a signal to the user
interface. Alarm (Bi..Bi..Bi...) sounds for 10 seconds, and alarm icon , will flash.
Pressure reading and icon will flash alternatively ( flash 3 second,pressure
reading flash 5 seconds).Those flashing icon can only be stopped when sensor
battery was replaced.
e.g.left front tyre battery low was detected,monitor alarm display as shown:
Custom ID Coding
The STP1400 is shipped with 4 sensors re-coded into the display, however should
you need to replace a sensor please follow these instructions. Below is Inflation
Code Learning to re-code the sensors ID:
Inflate Code Learning
1. In standby mode,quickly press SET button 5 times and release it after the
Bi... sound to enter learning mode,the Left Front digits will flash on the LCD.
2. Short press SET once to scroll tyre position needed to re-code.Once ready, then
mount the sensor on to the tyre valve, once the sensor sensed the inflation, the
sensor will send its own ID code to the monitor and the monitor will display the
sensor code after the Bi... sound. Repeat above step to re-code others sensor if
needed .
3. If the ID code was NOT detected, system will keep the old code unchanged.
4. Any new ID code will overwrite the old ID code when detected.
5. IMPORTANT press SET until Bi... sound to ensure the new code saved into the
monitor.
