5. After cleaning, rinse the end of the probe
thoroughly with clean water to remove all
traces of the liquid used.
6. Follow the instructions on the label of the
disinfectants.
7. The surfaces should then be dried with a
lint-free cloth.
CAUTION
DO NOT soak probes in alcohol for extended
periods of time, as damage can occur.
STORAGE
When not in use, it is recommended that the
power cord be disconnected and the EZ-S
CAN
be covered to keep dust and debris from entering
the system. While stored the EZ-S
CAN
should
be protected from temperature extremes and
humidity which can cause condensation within
the unit. The probes should be removed from
the EZ-S
CAN
and stored where they will be
protected from damage.
PROBE GENERAL INSPECTION
1. The probes should be checked daily for
function as well as for any visible damage.
2. Always check the cable for frayed or broken
wires which may interfere with the proper
functioning of the probe.
3. When connecting the probe to the instrument
be sure to align the red indicator dots on
both the jack and cable connector.
4. Verify that the internal fixation light of the
A-probe is operating.
5. Carefully examine the probe tip for any
chipping or rough edges which may injure
the cornea.
6. If applicable, examine the "Soft-Touch"
mechanism of the A-probe to ensure that it
slides freely and with minimal force.
CAUTION
DO NOT attempt to disassemble or lubricate
the slide mechanism as this may cause
permanent damage to the internal components.
It is recommended that the functionality of the
A-scan mode of the EZ-S
CAN
be verified by
means of the calibration procedure prior to
performing actual measurements.
The EZ-S
CAN
defaults into the Calibration
Screen every time the A-Scan mode is selected.
To perform the calibration procedure, follow
these steps:
1. Place a small amount of ultrasound coupling
gel onto the tip of the A-scan probe.
2. Place the probe onto the calibration cylinder
located on the right side of the system. The
probe should be placed perpendicular to the
cylinder.
3. Press the footswitch and observe the
measurement displayed on the touch screen
display. The measurement will freeze once it
has stabilized and a calibration status
message will be displayed.
4.
Verify that the measurement obtained is
10mm. ±0.1mm. If it is not, repeat the
calibration procedure until
an
acceptable measure is obtained.
IMPORTANT
If a measure within 10 ±0.1mm cannot be
obtained, contact Sonomed service department
for further help.
