TST Color Monitor Display
![App Diagram]()
- Current Tire Selection - The tire icons indicate the position of your tires. A solid tire icon indicates that tire is programmed into your current setup. A blinking tire icon indicates that tire is experiencing an anomaly.
- Sensor Low Battery Alert - This displays when one of the sensor's batteries is low. The corresponding tire light will also flash to indicate which sensor's battery is affected.
- Display Battery Level Indicator - Shows the charged level of the internal battery. When this icon shows one bar it is recommended to charge the display as soon as possible. It takes approximately 4 hours for the battery to fully charge.
- Out Of Parameter Alert - This icon will flash during a high or low pressure alert, a high temperature alert, or a fast leak alert. In conjunction with this flashing light, the affected tire light will flash, the HI or LO PRESSURE, HI TEMP, or FAST LEAK indicators will light up, and an audible alert will sound.
- Display Alerts - These icons, along with the specific tire icon, will light up to indicate HI or LO PRESSURE, HI TEMP, or FAST LEAK. The bottom row indicates which programming mode you are in.
- Red LED Indicator - Lights up during an alert.
- Antenna - The multidirectional antenna helps eliminate electronic interference when paired with the signal booster.
- Temperature Indicator - Displays the current temperature of the selected tire in Fahrenheit or Celsius. This will also display your selected high temperature parameter during programming.
- Tire Pressure Indicator - Displays the current tire pressure of the selected tire. This will also display your selected high and low pressure parameters during programming.
- Power Switch - Lets you turn the monitor on and off.
- Charging Port - Plug the included USB cable into this port to charge the monitor. The side power switch will not turn off the display when constant power is applied to the unit.
- Backlight and Motion Detector - The backlight turns on when the vehicle is in motion, and there is little ambient light. It will sense periods of inaction and the display will "go to sleep" until the vehicle resumes motion.
