Caring for your 403 LE

Phantom comes ready to scan. Do not remove surface material.

Store the 403 LE with cover closed securely.

Always attach the scanning surface cover and store the phantom out of direct sunlight
when it is not in use. Store in the plastic bag that is provided or in an air and water-tight
container.

Store the 403 LE at 35º –105ºF (2º–40ºC).

Freezing temperatures will damage the phantom and high temperatures will accelerate
desiccation.

Weigh the 403 LE to monitor desiccation.

Weigh the phantom when you first receive it and then every 6 months after that. Record
the values on the data sheet.

Do not drop or damage the phantom.

Return the phantom for inspection and/or repair if it has been dropped or damaged.
Physical damage to the case will cause premature desiccation. 

Gammex recommends annual servicing of your 403 LE to ensure proper operation. 

Our qualified service technicians will check for desiccation and provide any needed 

rejuvenation, scanning/certification to original specifications, and repairs.
