Tire Pressure Monitoring System
With Portable Monitor
User’s Manual
1. Introduction
The major components of the TPMS are: one sensor per tire, and a rechargeable battery operated handheld monitor. Each sensor is installed in the tire and continuously monitors the tire pressure and temperature, and transmits the readings wirelessly via RF signals to the monitor, which displays the tire information on its LCD screen. Upon detection of abnormal tire conditions the sensor immediately issues a warning signal. The monitor receives the signal and displays tire alarm status and, if necessary, issues an audible alert and turns on the status lamp on the monitor.

1.2 Important Monitor Safety Instructions
When using this unit, basic safety precautions should always be followed to reduce the risk of fire, electric shock, or personal injury.
1.Read and understand all instructions.
2.Follow all warnings and instructions marked on this unit.
3.Unplug this unit from power outlet before cleaning. Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning. Never spill any liquid on the unit.
4.Do not use this unit near water, for example when washing the vehicle, in the rain, near a lake or river, etc.
5.Place the unit securely on a stable location inside the vehicle. Damage and/or injury may result if the unit falls.
6.Never place the unit near a heat emitting source.
7.Use only the power source marked on the unit. If you are not sure of the power supply, consult your dealer or the manufacturer.
8.Do not place objects on the power cord of the battery charger.
9.Never push any objects through slots in this unit. This may result in the risk of fire or electric shock.
10.Do not disassemble this unit. Take the unit to an authorized service center when service is required. Opening or removing covers may expose you to voltages or other risks.
11.Unplug this unit from power outlets and refer servicing to an authorized service center when the following conditions occur:
a.When the battery charger power cord is damaged or frayed.
b.If liquid has been spilled into the unit.
c.If the unit has been exposed to rain or water.
d.If the unit does not work normally by following the operating instructions. Adjust only controls covered by the operating instructions. Improper adjustment may require extensive work by an authorized service center.
e.If the unit has been dropped or physically damaged.
f.If the unit exhibits a distinct change in performance.

12.Do not touch the power plug with wet hands.
13.The battery charger is used as the main disconnect device. Ensure that the vehicle AUX power outlet is near the unit and is easily accessible.
1.3 Important Battery Safety Instructions
To reduce the risk of fire or injury to persons, read and follow these instructions.
1.Use only the battery specified.
2.Do not dispose of the battery in a fire. They may explode. Check with local waste management codes for special disposal instructions.
3.Do not open or mutilate the battery. Released electrolyte is corrosive and may cause burns or injury to the eyes or skin. The electrolyte may be toxic if swallowed.
4.Exercise care when handling the battery. Do not allow conductive materials such as rings, bracelets or keys to touch the battery. Otherwise a short circuit may cause the battery and/or the conductive material to overhead and cause burns.
5.Charge the battery provided with or identified for use with this product only in accordance with the instructions and limitations specified in this manual.
6.Store the battery in a cool, dry and well-ventilated area.
7.Keep out the reach of children.
2. The Monitor
The monitor unit is the interface between the TPMS and the user. The monitor LCD screen has a graphical representation of the vehicle with tire icons, a thermometer icon, and a tire status icon. The screen also displays temperature and pressure readings.
There is a status LED on the upper right edge of the monitor. Below the status LED on the left there is a Control Button. Pressing the Control Button calls up in clockwise direction the next tire pressure and temperature readings, with a darken tire icon on the vehicle graphic indicating the associated tire location.
On the top right edge of the display unit there is a Setup Button for programming the system. Detail description of the setup procedures will be described in a later section. Pressing the Setup button turns on the back light of the LCD display.
2.1 Charge The Monitor Battery
The monitor has a rechargeable battery that can be safely charged with the included vehicle auxiliary power adapter. The monitor can only take on maximum power input of 5.5 volt DC. So if the user desired to use AC-to-DC power conversion chargers at home for the charging, make sure the converted power voltage did not exceed the limit. Use a volt meter to verify – actual output level is almost always at 2 or more volts higher than what’s listed on the label.
2.2 Turn On/Off The Monitor
The monitor can be turned on/off with the Battery Switch in the back side. When the monitor turns on it will clear all warnings and tire information, and the display will show “- -“ for the pressure and temperature readings. When the vehicle is moving new tire readings will appear after a few minutes, or could be up to a couple hours when parked. Notes: the sensors can detect whether the vehicle is in motion and will send out heartbeat signals every 3 to 5 minutes when moving; for a stationary vehicle the signal transmission slows down to once every couple hour for conserving sensor battery power. Nevertheless when abnormal tire situation occurs the sensor will send out warning signals as soon as it was detected.
2.3 Reset The Monitor
On rare occasions the monitor might appear to be in a frozen state and not respond to button pressing. In this case a hard reset would bring the monitor back to normal operation. On the back of the monitor there is a small hole – insert a pin through the hole to the end and press once, the monitor will come back to life.

3. Operation
After installation, the system operates automatically and continuously. When monitor power is on and receives tire sensor signals, the display will show the current tire pressure and temperature. Normally the green light is turned on. A flashing red light indicates low pressure; all other abnormal situations will turn on a flashing green light, and the corresponding tire indicator(s) and the warning icon(s) will appear.
The order of tire information display for 6-tire and 8-tire vehicles are showed below:
3. 1 Warnings
Upon detection of abnormal tire pressure and/or temperature the monitor will display one of the following warnings. The display lasts 8 seconds and then will switch to a screen as shown in Abnormal Situation Display (described in the next section). For severe warnings (low pressure and rapid pressure change) the system will also sound an 8-second alarm.
Low pressure or blowout The tire icon is hollow; indicating tire pressure is lower than the warning level, which usually is set to 12% below normal.
Slow air leak
The tire icon is 2/3 full; indicating tire pressure depletion of 3 PSI or more within 2 to 10 minutes.
High tire pressure The tire icon is full with
an outer shell; indicating the tire pressure is higher than the warning level, which usually is set to 25% above normal.
High temperature The high-temp icon is visible; indicating tire temperature is higher
than the warning level, which usually is set to 176 °F.
3.2 Abnormal Situation Display
A persistent abnormal tire situation (with possibly several tire abnormalities) will cause one of the following warnings to be displayed. The warnings are listed below in the order of precedence for display selection (from multiple abnormalities) by the system.
Low tire pressure (Highest priority)
High tire pressure
