®
- GSM ISDN GATEWAY Lite is designed to
be installed on a vertical surface. The required
working position is shown in fig. 2.
•
The ISDN GSM GATEWAY Lite may be operated in
another working position (e.g. lying on a table) just
temporarily – e.g. when being quickly tested during
servicing.
• The range of acceptable working temperatures and
humidity is quoted in the “Technical parameters“
chapter
.
• The ISDN GSM GATEWAY Lite must never be
operated in places with direct sunshine and near
sources of heat.
• If acceptable working temperature is exceeded it
does not have an immediate impact on the ISDN
GSM GATEWAY Lite function but it may result in
quicker ageing and loss of reliability.
•
The ISDN GSM GATEWAY Lite is designed for use inside buildings. It must not be exposed to
rain, leaking water, condensed humidity, fog, mist, etc.
The ISDN GSM GATEWAY Lite must not be exposed to aggressive gases, vapours of acids,
solvents, etc., nor it must be exposed to aggressive liquids, e.g. during cleaning of the cover.
•
The ISDN GSM GATEWAY Lite should not be used in high-vibration environment as means of
transport, plant-rooms, etc.
• Over and under the ISDN GSM GATEWAY Lite there must be a free space for cables and the
ventilation air that dissipates heat generated during operation.
•
The ISDN GSM GATEWAY Lite must be positioned with regard to GSM signal quality.
•
If you put the ISDN GSM GATEWAY Lite or antenna in an unsuitable position near TV, radio or
other receivers or other appliances sensitive to the high-frequency field, their function may be
impaired.
•
The ISDN GSM GATEWAY Lite antenna transmits high-frequency energy and this is why it
should not be very close to human body. The health risk is higher than in the case of mobile
phones as a GSM gateway usually transmits very often if more people use it for calling.
