Care and Maintenance
The PEM-320 is a precision optical instrument and as such requires reasonable care to be taken with its
handling, operation and storage. In particular:
• Do not drop or expose the unit to shock as this may cause misalignment of the optics,
• Do not expose the unit to direct sunlight or to extremes of temperature or humidity,
• Avoid letting dust, water, oil or other dirt into the unit and do not operate the unit within such an
environment,
• Do not apply a voltage exceeding that indicated in the specifications.
10.1. Care
10.2. Maintenance
Occasional cleaning of the exterior surfaces of the unit may be required. Please do not use chemical
cleaning agents. In particular, avoid chemicals that contain benzene, toluene, xylene, acetone or
similar solvents. A dry or slightly damp cloth is recommended.
The PEM-320 is based on a free space optics design. The optical connector is thus maintenance free
and does not require cleaning. The use of aerosols or similar cleaning techniques may cause
misalignment and damage to the optics.
