The User should observe the following instructions:
Equipment Connection
The CIC-50 is designed for operation ONLY with Comtech CDM-550 or CDM-550T
Modems. These Modems supply DC operating current (electronically fused and
protected) and control signals for the correct functioning of this unit. Connection to other
manufacturer’s equipment could result in damage to the unit.
Environmental
The CIC-50 must not be operated in an environment where the unit is exposed to
extremes of temperature outside the ambient range 0 to 500C, precipitation,
condensation, or humid atmospheres above 95% RH, altitudes (un-pressurised) greater
than 2000 meters, excessive dust or vibration, flammable gases, corrosive or explosive
atmospheres.
Operation in vehicles or other transportable installations which are equipped to provide a
