LifeSpan DT3 Console and C3-DT Desk Bike Owner’s Manual

Welcome

Congratulations on choosing the LifeSpan WorkplaceTM line of products. These products give you the opportunity to remain productive while taking care of yourself as you integrate movement with normally sedentary tasks.

The average American now spends eleven hours, five days a week, sitting, and burns one-hundred fewer calories each day than they did a few decades ago. Sitting for long periods slows your metabolism, reduces calories burned, and increases your risk for heart disease and diabetes.

Whether you plan on placing this product in a TV room, replace your desk at home or are adding another workspace in the office, LifeSpan WorkplaceTM products are a great way to add movement to an otherwise sedentary activity.

Before you assemble or operate your product, please read this manual thoroughly. Important information, including safety precautions, ongoing product maintenance, assembly instructions, and information on proper operation are included.

If you need to contact LifeSpan customer service, visit our website at www.LifeSpanFitness.com and select customer service.

Moving the C3-DT Desk Bike

Your C3-DT desk bike is equipped with two Transport Wheels (R) located on the rear support. Move the wire that is coming from the bottom of the frame to the console so it will not get pinched when moving the bike.

It may be difficult to roll the bike in plush carpeting.

Desk Bike Innovative Features

Personal Settings - there are several features that can be set using our Personal Settings feature to tailor LifeSpan desk bike to your specific preferences. These include:

Resume Level : after pressing pause and returning to the desk bike the default resistance will be 0, which is the normal starting speed. The resume resistance level can be modified to default to return to the previous resistance level.

In addition, the following features are applicable to desk bike users.

Audible Safety Beep : On / Off setting. Each time the control buttons on the console are depressed an audible beep is used as an alert that a change was made. This is designed to prevent accidental speed adjustments being made without users being aware that they may be accidentally depressing a button.
Metric versus Standard Readouts : Change the display readouts for speed and distance between Metric (SI) and English (EN).
Charging Port : This port can be used to charge your wireless mobile devices.

NOTE: You will not be able to save your workout data to a USB via this port; it is used for charging purposes only.
