3M Wireless Tire Pressure Monitoring System Operation Manual - page 5
System Declarations
When the wireless receiver and display unit detects a problem, the light indicator and the buzzer will continue to blink
and beep until the problem is corrected or the power is turned off. This is to ensure the warning effects of the wireless
receiver and display unit. Before the problem is corrected, the system will continue to display the problematic tire's light
indicator as well as its numerical value.
By pressing the Setup button for 3 seconds, the system enters into the pressure and temperature setup mode. If no
settings need to be modified, please press the Setup button three times to exit the setup mode. By doing so, all fault
light indicators and warning beeps are also cleared. However, if the system receives any abnormal signal again, the red
fault light indicators and warning beeps will reappear, alerting the driver that the tire needs to be repaired immediately.
System Setup
The following steps may be used by the driver to make system
adjustments and to change the default settings for all kinds of
warnings. (Note: This system contains factory default settings
configured according to the tire standards. Before adjusting
the settings by yourself, please consult the professionals if your
new settings can provide correct safety warning range with
regard to the tire pressure.)

Press and hold the Setup button on the upper side of the wireless receiver and display
unit for 3 seconds to make the system enter the Setup mode.
In the lower part of the display, the wireless receiver and display unit will first show the
red light indicators for Tire No.2 and No.3 (rear tires), the " psi " blue light indicator, the
numerical light indicator (26 psi is the low tire pressure warning factory default value),
and the " Lo " directive characters, indicating the system has entered into the low tire
pressure setup mode.
Step Operation
Illustration
Press the Function button on the front of the wireless receiver and display unit to configure
the low tire pressure warning value. By pressing the Function button once, the psi value
will add 1; and the psi value will return to 18 when it has received 35. The system will
use this setting as the standard value for low tire pressure monitoring, which means
when the tire has deflated to a pressure value lower than this setting, the system will
automatically start to warn the driver.
The user may adjust this setting (from 18 to 35) to meet specific requirements from
different tire categories. Note: Before adjusting the low tire pressure warning value by
yourself, please consult the tire specialists to see if there is any special requirement
from your tires which needs to be put into consideration when making adjustments to
this value.
After finish configuring this value, press the Setup button on the top side of the
wireless receiver and display unit once to exit the high tire pressure setup mode.
The system will automatically enter the high tire temperature setup mode.
The high tire pressure warning value can range from 40 to 60, and its factory default
value is 50 psi.
Press the Function button on the front of wireless receiver and display unit to adjust the
high tire pressure warning value. When the tire pressure exceeds this setting, the system
will generate warning signals.
The wireless receiver and display unit will now show the high tire pressure factory
default value (50 psi), the red light indicators for Tire No.1 and No.4 (front tires) and
the " psi " blue light indicator.
After you finish setting the low tire pressure warning value, the system will automatically
enter the high tire pressure setup mode.
