Electrical Safety

The CDM-700 Modem has been shown to comply with the EN 60950 Safety of Information
Technology Equipment, including electrical business machines
safety standard.

The equipment is rated for operation over the range 100 - 240 volts AC. It has a maximum power
consumption of 75 watts, and draws a maximum of 0.75 mA.

IMPORTANT

The user should observe the following instructions:

Fuses

The CDM-700 is fitted with two fuses - one each for line and neutral connections. These are

Environmental

The CDM-700 must not be operated in an environment where the unit is exposed to extremes of
temperature outside the ambient range 0 to 50°C (32° to 122°F), precipitation, condensation, or
humid atmospheres above 95% RH, altitudes (un-pressurized) greater than 2000 meters,
excessive dust or vibration, flammable gases, corrosive or explosive atmospheres.

Operation in vehicles or other transportable installations that are equipped to provide a stable
environment is permitted. If such vehicles do not provide a stable environment, safety of the
equipment to EN60950 may not be guaranteed.
