Warnings, Cautions, and Notices
Notice
If you plan to connect the handpiece for activation, ensure that an I.V. set is
available to supply cooling irrigation solution to the handpiece tip. Otherwise,
damage to the tip and/or handpiece may result.
Electrostatic Sensitive Devices This unit contains electrostatic sensitive
components. When repairing the system, work at a static control workstation.
Wear a grounding strap when handling electrostatic sensitive components.
Handle circuit boards by their nonconductive edges. Use an antistatic container
for transport of electrostatic sensitive components and circuit boards.
When installing a new power supply, use the same screws and washers removed
from the previous power supply. A too-long screw will damage the power supply.

Calibration
High Current Hazard Do not touch the ultrasonics PCB heat sink while the
CUSA EXcel system is energized. The heat sink is isolated from ground, and can
deliver very high current, resulting in injury.
Repair Policy
To prevent the ramp from falling and causing injury, be sure to hold the ramp in
the up position while stapling the corrugated tab that secures it to the crate.
