MAINTENANCE AND TROUBLESHOOTING

Inspect and tighten all parts of the exercise bike regu-
larly. Replace any worn parts immediately.
To clean the exercise bike, 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.
CONSOLE TROUBLESHOOTING
If lines appear in the console display, see step 4 on
page 24 and adjust the contrast level of the display.
If the console does not display your heart rate when
you use the handgrip heart rate monitor, see step 5 on
page 18.
If the console does not display your heart rate
when you use the chest heart rate monitor, see
TROUBLESHOOTING on page 12.
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, you must first remove the left pedal, the left
disc cover, and the left pedal disc (see the instructions
