A.1 Troubleshooting
The following table lists common problems and potential solutions to help you when installing your router. Please
contact your dealer for further information if you are unable to solve a problem.
Problem Solution

Check the SIM tray configuration is correct.
A.2 Maintenance
Teldat H2 RAIL routers are designed to be highly available and durable, and for this reason have no moving parts.
This design makes any maintenance unnecessary.
A.2.1 Anticorrosion measures to protect the device's metal parts during trans-
portation, storing or at its final location
As far as the metal housing is concerned, the Teldat H2 RAIL router was designed to be placed in an enclosed
space, protected from bad weather; never to be exposed or subject to these or any other extreme environmental
conditions.
The device housing is made of galvanized iron sheet with an epoxy and polyester resin-based powder paint coating,
added for aesthetic and anti-corrosion purposes. These characteristics give the housing the ability to withstand the
effects of external corrosive agents (oxidation) to which the device might be exposed during transportation, storage
or at its final location. As previously mentioned, these locations must always be indoors, sheltered, and not exposed
to extreme environmental or meteorological conditions.

However, there are various considerations and measures that need to be taken into account during the transporta-
tion, storage and final deployment of devices to prevent the metal parts of the device from rusting.
• Devices should be stored indoors or in places that are dry, clean and away
from chemicals.
• Do not subject the device to sudden rapid changes in temperature that could
lead to condensation (which, in turn, will cause the metal parts in the devices
to rust). Try to maintain the device at a temperature as constant as possible.
