Maintenance
Periodic Visits
Periodic visits (every three/six months depending on the installation environment)
should be planned for:
• Checking the display
• Checking the mounting
• Cleaning the optical aperture of the transceivers
• Cleaning the building windows for indoors installations.
At cleaning time, the reading of the digital readout should be marked
down in a service log book. Once the optical aperture is cleaned, if
the reading is substantially lower than that noted at installation time,
the aiming accuracy should be examined and restored if necessary.
Note
Aiming accuracy should be checked looking through the telescope and comparing
the present scene sighting to the one sketched in the Installation Log at installation
time.
