Minimizing Radiation Damage
The electronics are located between the “KEEP DIRECT BEAM ABOVE THIS LINE” marking and
the cable connection ports. To minimize damage to the electronics:
• Do not expose the device electronics to the direct beam.
• Do not leave MapCHECK 3 on the couch exposing to direct radiation during delivery system
warm up.
• If MapCHECK 3 is stored in the treatment room, ensure it is not exposed to direct radiation
when the gantry is rotated.
• Avoid frequent use of thick buildup which may cause scattered radiation and damage the
electronics.
Inspection
Periodically inspect MapCHECK 3 housing, casing, cables, connectors, and all ancillary parts for
damage. If any mechanical or electrical degradation is suspected, if errors are suspected, or if the
device cannot be calibrated to provide consistent measurements, discontinue use and contact
Sun Nuclear Support. See
Contacting Sun Nuclear Support on page 15.
Repair
There are no user-serviceable parts in MapCHECK 3. If there are problem with the device or
ancillary parts or accessories, contact Sun Nuclear Support. See Contacting Sun Nuclear Support
on page 15.
Cleaning
Clean MapCHECK 3 by vacuuming or wiping with a clean, dry cloth. If necessary, clean external
surfaces with a cloth moistened with mild cleaning solution. Do not use any solvents or abrasive
cleaners.
Do not immerse MapCHECK 3 in any fluid. Do not permit liquid to flow on the device or any
associated parts or accessories, or into any cavity.
Storage
Store the device, ancillary parts, and accessories in an indoor, protected environment consistent
with conditions stated in Specifications on page 21.
Disposal and Recycling
The MapCHECK 3 contains electrical components. In some countries the disposal of electrical
components is subject to special requirements. When the components are no longer functional
or are otherwise ready to be discarded, recycle or dispose of them according to local waste
management or recycling regulations.
CAUTION: The MapCHECK 3 has dosimeters between the electronics and detector
array. The dosimeters are read when the MapCHECK 3 is returned for service. An indi-
cation of direct radiation to the electronics will VOID the warranty.
