Operating Environment
CAUTION
Do not operate the unit in any of these extreme operating conditions:
•
Ambient temperatures less than 0°C (32°F) or more than 50°C (122°F). (maximum
storage temperature allowed is -25°C (-13°F) to 85°C (185°F)).
•
Precipitation, condensation, or humid atmospheres of more than 95% relative humidity.
• Unpressurized altitudes of more than 2000 metres (6561.7 feet).
• Excessive dust.
• Flammable gases.
•
Corrosive or explosive atmospheres.
European Union Radio Equipment and Telecommunications Terminal
Equipment (R&TTE) Directive (1999/5/EC) and EN 301 489-1
Independent testing verifies that the unit complies with the European Union R&TTE Directive, its
reference to EN 301 489-1 (Electromagnetic compatibility and Radio spectrum Matters [ERM];
ElectroMagnetic Compatibility [EMC] standard for radio equipment and services, Part 1: Common
technical requirements), and the Declarations of Conformity for the applicable directives, standards, and
practices that follow.
•
Use coaxial cable that is of good quality (e.g., RG58/U (50
Ω) or RG59/U (75Ω)) for connections
to the IF Tx and Rx (transmit and receive) BNC female connectors.
•
Use Type 'D' connectors that have back-shells with continuous metallic shielding.
•
Type ‘D’ cabling must have a continuous outer shield (either foil or braid, or both). The shield
must be bonded to the back-shell.
•
Operate the unit with its cover on at all times.
