CAUTION
Turn OFF the power to, and UNPLUG the WaveBook and all connected equipment.
Remove all signal I/O lines from the unit. Electric shock or damage to equipment can
result even under low-voltage conditions.
Take ESD precautions, to include using a grounded wrist strap.
Use care to avoid touching board surfaces and onboard components. Ensure boards
do not come into contact with foreign elements such as oils, water, and industrial
particulate.
You should only replace a fuse if your device shows no sign of damage. If your device
appears damaged such as evidenced by a “smoked” component, contact the factory as
soon as possible.
If the replacement fuse blows, contact the factory as this indicates a problem may
exist with your WaveBook.
