QUICK REFERENCE

IMPORTANT! Follow all instructions here before operating the BioHarness 3. Make sure your strap is
the correct size before using it (available in two sizes, Small XS-M or Large M-XL). For more details,
refer to the BioHarness 3, RAELink3 (or RAELink3 Z1, which has the same functions), and ProRAE
Guardian User’s Guides or Quick References.

The BioHarness 3 measures the following parameters:

Operation

1. Moisten the gray sensor pads on the back of the strap with water.

2. Snap the BioHarness Echo Module onto the BioHarness 3 by clicking the bottom in first and then the top.

3. Power on the BioHarness Echo Module by pressing the button in the center until all four LEDs flash.

4. Link the BioHarness Echo Module to the RAELink3.

Note: It links automatically after the initial Bluetooth pairing.

5. Attach the shoulder strap with Velcro in the back and fit the clasp to the loop in the front, and

then do the same with the clasp and loop in the front.

Note: BioHarness Echo Module should be under the left armpit when properly positioned.

Quick Reference.

Charging The BioHarness Echo Module

1. Snap the BioHarness Echo Module into the Charging Cradle and use a USB cable to connect the

Charging Cradle to a computer or the included USB charger.

2. Snap the BioHarness Echo Module into the Charging Cradle and allow it to charge. Typical

charging time for a full charge is 3 hours. A charge of 90% is typically reached in 1 hour. While
charging, the BioHarness Echo Module’s orange LED flashes. When fully charged, the orange
LED glows continuously.

3. Once it is charged, remove the BioHarness Echo Module from the Charging Cradle.

Pairing The BioHarness Echo Module And The RAELink3 Via
Bluetooth

After an initial pairing of the BioHarness Echo Module with the RAELink3, the two will automatically
find each other every time they are turned on. For initial pairing, follow the instructions below.

Note: When doing initial pairing, never turn on more than one BioHarness Echo Module and one
RAELink3 at the same time.

1. Enter Programming Mode on the RAELink3 by holding the [N/-] and [MODE] keys together.

 Press [N/-] twice until you see “OP Mode” (Operation Mode).
