Introduction

Cardio 30, the smallest GPS sports watch on the market, is for all levels of athletes. By setting goals in the pre-training programs, Cardio 30 can accurately calculate and record your location, speed, distance, pace, stride rate, cadence*, heart rate*, and more. Your training results can then be shared and analyzed at brytonsport.com. Also, with the built-in sensor in Cardio 30, no extra foot pod is needed for indoor exercise.

Package Contents

Make sure the following items are in the box:

Cardio 30•

USB cable•

User's Guide•

Optional accessories:

Heart rate monitor•

Speed / Cadence sensor•

* HRM or SPD/CAD sensor is required.

Getting Started

Step 1. Connect, Sync, and Charge

1. Connect Cardio 30 to a PC using the supplied USB cable.
2. Download the Bryton Bridge application at bb.brytonsport.com and sync with Cardio 30.

bb.brytonsport.com

Note: For first time use, charge the battery for at least 2.5 hours.

Step 2. Turn On

Short press the OK button to turn on Cardio 30.

Note: To turn off, long press the OK button for 5 seconds.

Step 3. Initial Setup

For first time use, the setup wizard appears.

1. Select your preferred language.
2. Select the unit of measurement.

3. Enter your user profile (recommended).
   Note: Data accuracy will highly affect your training analysis.

4. Enter your max heart rate.

5. Go outdoors to acquire GPS signal. Once the GPS signal is fixed, Cardio 30 automatically sets the date and time. To manually set the date and time, go to Time settings (see page 8).
6. Press OK to complete setup.

Note: Availability of the Stride Length setting depends on the selected training type: Stride length is not available in BIKE training.

In RUN training, CALIBRATE is not available because the built-in sensor calibrates • your stride length automatically or you can manually input it by SET.
