Electrical Connections The WCM-02 is designed to operate from switched 9.8-32Vdc power. It should typically be connected to the ignition signal so that the display is on when the vehicle is running, and off otherwise. - Page 4 PreCise MRM Installation and Operation Manual WCM-02 Figure 1: Wiring for WTS-01 Figure 2: Wiring for TS-01 1311 East Franklin Road, Suite 102 www.PreCiseMRM.com WCM-02C a subsidiary of FORCE America Copyright 2017 Meridian, Idaho 83642 Support: 1-888-254-1634 Sales: 1-888-449-0357 p. 4 of 14...

- Page 7 PreCise MRM Installation and Operation Manual WCM-02 • Hit the SELECT button. • With “Scan sensors” underlined, hit SELECT again. • While the display shows “Scanning” install the battery in the sensor or tap it a few times to wake it up. If you are pairing to a wired sensor, it will transmit as long as it has power.

Brightness Control The brightness of the display can be controlled in a few ways. Even after power is removed from the display, it will remember the last setting. - Page 9 PreCise MRM Installation and Operation Manual WCM-02 Units Configuration (°F or °C) Once the configuration is selected, the setting is saved until the next time it is changed. • Hit the MENU button. • Use the UP (▲) and DOWN (▼) buttons to underline “Configuration”.
- Page 10 WCM-02 Signal Strength This screen shows the relative strength of the wireless signal that the WCM-02 is receiving from the sensor. The signal strength can range from 1 to 255. The higher the number, the better, but even a low value will be sufficient as long as the signal is received consistently. This screen can be used to evaluate the physical placement of both the WCM-02 and the temperature sensor.
- Page 11 The time between temperature and humidity readings being sent from the wireless sensor (WTS-01) to the WCM-02 display is controlled with this setting. The wired sensor (TS-01) will report every second, regardless of this setting. Once the interval is selected, the setting is saved until the next time it is changed.
- Page 12 PreCise MRM Installation and Operation Manual WCM-02 Accel Settings The wireless sensor (WTS-01) will “wake up” and determine if its paired display is on, based on sensing movement via the built-in accelerometer and periodically based on the wake interval. The wired sensor (TS-01) does not have an accelerometer. This screen will show the latest accelerometer readings in each axis, as well as the peak readings.
- Page 13 PreCise MRM Installation and Operation Manual WCM-02 Wake Interval The wireless sensor (WTS-01) will “wake up” and determine if its paired display is on, based on sensing movement via the built-in accelerometer and periodically based on the wake interval. The wired sensor (TS-01) will report as long as it has power, regardless of this setting.
- Page 14 PreCise MRM Installation and Operation Manual WCM-02 Accel Threshold The wireless sensor (WTS-01) will “wake up” and determine if its paired display is on, based on sensing movement via the built-in accelerometer and periodically based on the wake interval. The wired sensor (TS-01) does not have an accelerometer. If the accelerometer detects movement above the threshold setting, it will wake the sensor.
