shown in the IOL table
( only)
Verify that all necessary
IOL data have been
entered (i.e. k-readings,
formula constants, etc.)
Inconsistent axial length
measurements
obtained.

Check anterior chamber
depth measurements – if
inconsistent, may reflect
corneal compression
occurring during
applanation

3. If problem cannot be solved, please contact
Sonomed service department for further
help. Prior to contacting Sonomed, please
gather as much information as possible
concerning the specific problem, and have
the system and probes nearby. This will
greatly aid the service representative in
determining the cause of the problem.
If it is deemed necessary to return the system
and/or probes to Sonomed for service, a
return authorization will be issued. Please
ensure that any materials returned to
Sonomed are adequately packaged to avoid
any damage during shipment.
ELECTROMAGNETIC INTERFERENCE
At times during normal use, the operator may
experience periods of interruption caused by
interference from outside sources such as
electrostatic discharge, power generators or
other office equipment.
Should any outside interference cause the
system to “lock-up” or begin to operate in a
manner inconsistent with the manufacturers
instructions, simply turning the unit off for a few
seconds will usually resolve the problem.
In some cases a “hard-reset” must be performed
by the operator. This will cause all stored data
to be replaced with the factory default settings,
and should therefore only be used when
absolutely necessary. For instructions on
performing a system reset, the operator should
contact the Sonomed service department at 800-
227-1285.
