2N - ISDN BRI GSM Enterprise Gateway
The allowed working temperature and relative humidity ranges
are included in Section 10 .
•
Exceeding the recommended operating temperature values
need not affect the gateway function immediately but may
result in more rapid ageing and lower reliability.
•
The gateway is intended for indoor use. It may not be exposed
to rain, flowing water, condensed moisture, fog, or mist.
•
The gateway may not be exposed to aggressive gas, acid
vapours, solvents, etc. or aggressive liquids, during cover
cleaning, for example.
•
The GSM gateway is not designed for high-vibration
environments, e.g. means of transport, machine rooms, etc.
•
Free space has to be left under and over the gateway for cables
and agitated air to remove operational heat.
•
Install the gateway on a place with a good GSM signal.
•
A misplacement of the GSM gateway or its antenna near
television, broadcasting or similar RF-sensitive devices may
evoke an adverse effect upon their function.
•
Being a source of RF energy emission, the gateway antenna
should not be located close to human bodies. The hazard
is higher than with mobile telephones because the gateway
is usually used by many people and thus employed more often.
