The site must be free of strong electrical or magnetic fields, which cause disrupted signals
and, in extreme cases, system failure.
The site must maintain a temperature between 32°F and 90°F. Be sure to guard against tem-
perature fluctuations. Resulting condensation can cause a short circuit. The humidity level
may not exceed 80%.
To avoid overheating the system, make sure the site provides adequate ventilation.
Regular servicing ensures that your CELLX Box runs trouble-free. Servicing also includes look-
ing after the room in which the CELLX Box is set up. Ensure that the air-conditioning and its
filter system are regularly checked and that the premises are cleaned on a regular basis.
