Quick Start Guide Protocol:  Device Indicator Lights

TracPatch uses indicator lights to understand how the devices are functioning.

Follow the instructions provided in the Quick Start Guide to turn on and connect the devices to the phone through the TracPatch App and use this resource to help you understand what the lights indicate.   

What device lights will I see when I plug in the charging base?

While devices are in the charger, the back of the devices will initially flash multi-color when first turning on. 

You will see intermittent green and blue lights around the edges of the back of the devices indicating charging mode.

You will also see flashing white lights on the back of the devices. These indicator lights are used for skin tone color calibration during self-calibration. 

In rare cases, the edge of the device may be red indicating a low battery.   Please leave this device in the charger for at least 4 hours or until the edge

of the device turns to green.

Charging Base LED Indicator Lights While Devices are Charging

Intermittent Solid Blue line indicates the devices are receiving a charge

Solid Red line indicates Charger Error: Reset by reconnecting the power cable.

What device lights will I see when Entering My Devices?

Take the devices out of the charger to see the white and blue stickers on the front.

• The white device will have a blinking blue light (looking for Bluetooth connection to the phone)

• The blue device will have a blinking green light (connected to the white device and good to go).

Devices should have enough battery to collect data for the first day but should be charged nightly.

In rare cases, a device may have a blinking red light indicating a low battery.

Follow the instructions in the Quick Start Guide to enter the devices into the Patient App. 

·       Once completed, both devices should be blinking green indicating they are ready to start collecting data and good to “go”.

·       ** After this is completed, you can view the battery status and Bluetooth connection from the Status Page within the Patient App.

Troubleshooting:  Contact Customer Support for assistance

If the white device is not blinking green after this step, it is having difficulty connecting to the phone’s Bluetooth.

If the blue device is not blinking green at any time, it is having difficulty connecting and communicating to the white device. 

If devices do not appear to be charging correctly, please contact Customer Support for assistance.
