d= New faults since last check
Note: Each section has faults
listed in order of priority. For
each section, only the highest
priority fault is returned. There
maybe multiple faults for each
section, but only the highest fault
is returned.

Metric Conversion
Metric conversion information is located on the inside back cover of this manual. This information
is provided to assist the operator in cross-referencing non-metric to metric conversions.
Cautions and Warnings
WARNING indicates a potentially hazardous situation that, if not avoided, could
result in death or serious injury.
CAUTION indicates a hazardous situation that, if not avoided, may result in minor
or moderate injury. CAUTION may also be used to indicate other unsafe practices
or risks of property damage.
IMPORTANT or NOTE Indicates information critical for proper equipment function.
Recommended Standard Designations
Recommended Standard (RS) Designations have been superseded by the new designation of the
Electronic Industries Association (EIA). References to the old designations are shown only when

depicting actual text displayed on the screen of the unit (RS-232, RS-485, etc.). All other references
in the manual will be shown with the EIA designations.
Electrical Safety
The CDM-710G High-Speed Satellite Modem has been shown to comply with safety standard EN
60950: Safety of Information Technology Equipment, including Electrical Business Machines.
The equipment is rated for operation over the range 100 to 240 VAC. It has a maximum power
consumption of 88 watts, and draws a maximum of 770 mA.
Fuses
CAUTION
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH
THE CORRECT TYPE AND RATING.
The CDM-710G is fitted with two fuses - one each for line and neutral connections. These are
contained within the body of the IEC power inlet connector, behind a small plastic flap.
•For 115 and 230 volt AC operation, use T2.00A, 20mm fuses.
•For 48 VDC operation, use T6.25A, 6.3x32mm fuses.
Environmental
The CDM-710G shall 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 (unpressurized) 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.
Installation
The installation and connection to the line supply must be made in compliance to local or national
wiring codes and regulations.
The CDM-710G is designed for connection to a power system that has separate ground, line and
neutral conductors. The equipment is not designed for connection to power system that has no
direct connection to ground.
The CDM-710G is shipped with a line inlet cable suitable for use in the country of operation. If it
is necessary to replace this cable, ensure the replacement has an equivalent specification.
Examples of acceptable ratings for the cable include HAR, BASEC and HOXXX-X. Examples of
