2 User safety information
The following information applies to the coM.sat ISDN Basic. As the cellular engines
used in this device are manufactured by Siemens (TC35i), we explicitly refer to this
company’s respective safety regulations and operating manuals.
2.1 Electrical safety
The coM.sat ISDN Basic works with a nominal supply voltage of about 10 V.
Furthermore, the device is connected to the S
0
local port of TAs. Therefore no further
precautions are required to protect the user against high voltages from this device.
However, it should be noted that the user must ensure that they discharge any static
charge they may have before working on the device.
2.1.1 Air traffic safety
Use of cellular engines in aircraft can impair their navigation systems and interfere
with the mobile radiophone network. Their use has therefore been forbidden by law.
The coM.sat ISDN Basic must therefore not be used on board aircraft. Breach of
requirement can cause temporary or complete suspension of the cellular engine
services and / or legal steps to be taken against the offenders.
2.2 Environment with explosive materials
The coM.sat ISDN Basic is not approved for use in potentially hazardous
atmospheres. The user is therefore advised not to use the TA close to such areas,
which could be e.g. at petrol stations, in fuel depots, in chemical works or during
blasting. Should this nevertheless be necessary, the user should take steps to
ensure that no risk can occur.
2.3 Road traffic safety
If the devices are used in vehicles that are used in public road traffic, the national
regulations for telephoning in vehicles applicable for the country in which the device
is must be complied with.
2.4 Non-ionising radiation
As in all radio transmission devices, the user should note that it is advisable for
satisfactory use of the devices and safety of the user that the device is only used in
its normal operating position.
2.5 Electronic medical equipment
The operation of radio transmitters, which includes cellular engines, can impair the
function of medical devices that have not been properly shielded. Please ask advice
of your doctor or the manufacturer of the medical device.
