Tire Pressure Monitor TPM-S1/TPM-S2

TPM is one of the most advanced automobile tire pressure monitoring system. This system
can automatically monitor your tires while you are driving your car. When any of the tire
pressures fell under a safety level, the system will issue warning signals to notify you.
The TPM can display individual tire pressures, which allows you to know your tire
pressure situation at all time while you are driving. In addition, this system is very easy to
install and very simple to operate. It enables you to always keep your tires properly
inflated and, thereby, reduce your tire thread wears and prolong your tire lives. The best
value TPM brings you is the peace of mind while driving, knowing that when you tires
have problems, you will have advance warnings.

1 System Installation

1.1 System Parts

Sensor Module
Monitor Module
Auxiliary Power Adapter
DC power connector
Connection cable

1.2 Sensor Module Installation

The product package includes four long-life button battery packs, one for each sensor
module. To install the battery: open the sensor module cap by hand, insert the battery
pack into the battery compartment, then close the sensor module cap. Be sure to install
the battery with the proper polarity allocation, and make sure not to touch the electronics
inside the sensor module for it might affect system operations.

On top of each sensor module cap there is a tire position mark, which:

!"1R, indicates that it is for the right-front tire;
!"2R, indicates that it is for the right-rear tire;
!"1L, indicates that it is for the left-front tire;
!"2L indicates that it is for the left-rear tire.
!"2RI indicates that it is for the right-rear inner tire (6 tire option).
!"2LI indicates that it is for the left-rear inner tire (6 tire option).

Replace each tire valve stem cap with a sensor module and then tighten the sensor
module by hand. Make sure the sensor module is installed to the correct tire that is
corresponded to its position indicator.

1.3 Tire Pressure Monitor Installation

Usually the monitor unit is placed on top of the dashboard, on the driver side near the
windshield glass, with the display panel facing the driver. This way the power adaptor
cable can run around the instrument panel and then go above or beneath the steering
wheel, with the plug to be inserted into the cigarette lighter socket. The monitor unit can
also be put inside the vehicle in any place that the user considered to be easily accessible.

2 How to Use the System

2.1 Monitor Module Display Panel

Please see the display panel drawing.

2.2 Initial Situation Display

In order to conserve the battery power inside the miniature sensor module, the sensor is
shut down (i.e., not operational) when the automobile is stationary or when its speed is
less than 15 miles per hour (mph). When the car speed reached 15 mph or above, all
sensor modules installed on the vehicle tires will automatically turn on and enter the
operation mode, and will immediately transmit the tire pressure reading to the monitor
unit. Upon receiving the pressure readings, the monitor will display individual tire
pressures, one after another, to notify the user. In every 4 seconds, the display panel will
show tire pressures in the following (clockwise) order: right-front tire (1R), right-rear tire
(2R), right-rear inner (2RI, option), left rear (2LI, option), left rear (2L), and left front
(1L). At this time if the automobile speed maintained at 15 mph or higher, the individual
tire pressures will be displayed twice, in two cycles. The initial situation display allows
the user to learn about each tire’s pressure condition when the vehicle is picking up
speed. After completion of the initial display, in order not to distract the driver, the
system will enter automatic monitoring mode and will not display any normal pressure
readings; only the greed LED on the monitor is lit to indicate the system is operational.
