over the course of the procedure. CAO Group makes available
barrier sleeves for the Display Module and the Handpiece
assembly. See Section 9 for ordering information.
4.2. Foot Pedal Battery Replacement
Follow these procedures to replace the foot pedal battery.
1. Make sure the Base Module is completely turned off before
replacing the battery in the foot pedal.
2. Place the pedal face-down on a hard, clean surface.
3. Use a Phillips head screwdriver to remove the four screws
securing the base plate to the foot pedal housing.
4. Remove the base plate.
5. Remove the battery from the compartment and detach the
battery terminal.
6. Remove the new battery from its package and attach the
battery to the terminal.
7. Insert the new battery into the compartment. Make sure the
connector is on the same side of the compartment as the
lead wires that attach to the terminal. Make sure all lead
wires are placed back inside the compartment.
8. Replace the base plate and screw in the four screws until
moderately tight. DO NOT over-tighten the screws.
9. Place the pedal face up. Allow 1 minute after completing
this process to check the pedal functionality as described in
Section 2.10.
NOTE: An extra 9-volt battery should be kept on
hand in case the battery needs to be replaced
during usage.
NOTE: The battery supplied with the Precise SHP
system is a non-rechargeable lithium battery that
provides for approximately 100 hours of usage. It
is recommended that the replacement battery also
be a lithium battery. The more common alkaline
type battery may be used, but be advised that these
batteries only provide approximately 35 hours of
use.
NOTE: During operation, the status of the battery in
the foot pedal can be monitored. See Section 3.2.8.
4.3. Maintenance and Servicing
This manual describes the steps necessary to operate and
maintain the Precise SHP in a proper working condition. If
difficulties are encountered, please refer to the applicable
sections of this manual. If the care and cleaning of the device
is followed as described, the Precise SHP will provide years of
consistent performance. No other maintenance activities should
be needed or undertaken. No portions of the Precise SHP
are serviceable by the operator. If any errors or malfunctions
are encountered, please contact the CAO Group Service
Department (877.236.4408) as described in Section 6.2.
CAUTION: Do not open or attempt to service the
Base Module. Exposure to visible and invisible
laser radiation may occur.
WARNING: No modification of this equipment
is allowed. Attempting to alter, or to perform
maintenance not specified in this manual could
create risks of electric shock, hazardous laser
radiation exposure, and will void the warranty.
4.4. Calibration
The Precise SHP Laser uses solid-state circuitry to continuously
monitor the power output and adjusts the power supplied to the
laser module to keep the output consistent with the user defined
setting. If output levels are more than ± 20% of the set value,
the unit is designed to shut down power to the laser, and an
audible alarm will sound. If this happens, the unit should be
turned off and allowed to sit for 5 minutes and turned on again.
If the laser then performs without beeping, the microprocessor
has been able to make operational adjustments and the unit will
perform its functions. If, upon restart, the unit continues to beep,
the unit will need to be sent in for adjustment by CAO Group,
Inc., Service Department.
We suggest that your practice establish an internal calibration
program for your laser. Recalibration is recommended at
a minimum of once per year based on average usage.
Recalibration may be performed by the manufacturer by
returning the unit. Alternatively, you may purchase a calibrated
hand–held power meter approved for use with 810nm devices
to check power output. Output should be checked at the 1, 2,
