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 noted in |
( |
| |
| a service log book. If after the optical aperture is cleaned 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.
