MAINTENANCE AND TROUBLESHOOTING

Inspect and properly tighten all parts of the exercise cycle regularly. Replace any worn parts immediately.

To clean the exercise cycle, use a damp cloth and a small amount of mild soap. Important: To avoid damage to the console, keep liquids away from the console and keep the console out of direct sunlight.

PULSE SENSOR TROUBLESHOOTING

For optimal performance of the pulse sensor, keep the metal contacts clean. The contacts can be cleaned with a soft cloth—never use alcohol, abrasives, or chemicals.

Avoid moving your hands while using the pulse sen- sor. Excessive movement may interfere with heart rate readings. Do not hold the metal contacts too tightly; doing so may interfere with heart rate read- ings. For the most accurate heart rate reading, hold the metal contacts for about 15 seconds.

HOW TO ADJUST THE REED SWITCH

If the console does not display correct feedback, the reed switch should be adjusted. To adjust the reed switch, the left side shield must be removed.

First, remove the seven M4 x 25mm Screws (41) from the Right Side Shield (18). Next, remove the M4 x 12mm Round Head Screw (29) from the right side of the Side Shield Cover (19).

BATTERY REPLACEMENT

If the console display becomes dim, the batteries should be replaced; most console problems are the result of low batteries. To replace the batteries, see assembly step 4 on page 5.
