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—never use alcohol,
abrasives, or chemicals to clean the exercise
cycle.
Important: To avoid damage to the console, keep
liquids away from the console and keep the con-
sole out of direct sunlight.
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 5 on page 5.
PULSE SENSOR TROUBLESHOOTING
For optimal performance of the pulse sensor, keep the
metal contacts clean. Clean the contacts with a soft
cloth—never use alcohol, abrasives, or chemicals
to clean the metal contacts.
Avoid moving your hands or squeezing the metal con-
tacts too tightly while using the pulse sensor; doing so
may interfere with heart rate readings. For the most
accurate heart rate reading, hold the metal contacts
for about 15 seconds.
