Repeat Measurement -
The light on one side of the patient’s head is brighter than the
other and the amplifiers need to begin the measurement with a lower gain. Re-take the
data of the pair.
Saturated, Start in Reverse Order
– the Infrascanner has detected a potential hematoma
and needs to re-take the data in the reverse order (right side first) to confirm. The
message always occurs when a hematoma is present on the left side (first side of pair to
be measured).
Timeout
– Infrascanner gains unable to converge quickly enough. Move the light guides
5mm and repeat the measurement.
Unstable Signal
– Caused by variations in the signal level. Repeat the measurement at
the site taking care to hold Infrascanner steady.
Communications Error
– Software error. Take off the Disposable Fiber Optic Shield and
put it back on to reset the Infrascanner.
Battery is Low
– Charge the Infrascanner.

CLEANING, PREVENTIVE INSPECTION AND MAINTENANCE
Cleaning
Clean the Infrascanner exterior surfaces monthly (or more frequently if necessary) with a
damp cloth or sponge. Use alcohol or mild cleaning solutions to remove stains or
adhesives that may stick to the surface. DO NOT immerse the Infrascanner in any
solution. Subjecting the Infrascanner to excessive moisture may damage the electronic
components and nullify the warranty. Always ensure that the cradle pins are clean of
debris in order to communicate properly with the Cradle.
Preventive Inspection and Maintenance
Ensure that the windows over the detector and laser are clear of debris. No special
cleaning solutions are required. If necessary wipe with a soft tissue damp with alcohol.
View through the Disposable Fiber Optic
Shield’s light guides and verify that there are no
obstructions to the light path through them. Always use the provided medical grade Cradle
Power Adapter for connecting to the Cradle. Any other power supply could damage the
charging circuitry and/or the Nickel Metal Hydride rechargeable battery.
Sterilization
Never sterilize the Infrascanner or the Disposable Fiber Optic Shields.
Replacement of Batteries
Use a
¼” flat blade screwdriver to release the battery door latch by turning one half turn
counter clockwise.
To change the AA disposable batteries, remove the used disposable batteries per the
image below. Ensure that proper polarity is observed when inserting the new batteries.
Replace the battery door and engage the latch.
