those recommended by Teldat.
Teldat has a series of accessories (90º mount antennas, antennas for exterior installation, antennas for ceiling install-
ation, extension cables, etc.) that allow you to install the devices in different locations.
3.5.2.1 Placing the Antenna
The orientation of the Teldat 4Ge and its location with respect to other wireless devices or other radiation sources
(such as communication devices, personal computers, etc.) can significantly influence the performance level of the
equipment.
The Teldat 4Ge transmits and receives radio signals. This performance is also affected by environment factors such
as the distance between the device and the base station, physical obstacles and other interferences due to radio fre-
quencies (RF).
In order to receive better coverage, follow the instructions given below:
• Whenever possible, position the antenna in a place where there are no physical obstacles. Obstacles between the
antenna and the base station degrade the wireless signal. Place the antenna above ground level and steer it to-
wards the nearest base station.
• The density of materials also affects the antennas. Position it away from all types of walls, metal screens, mirrors,
etc.
• Do not place the antenna near columns that could throw shadows and reduce the coverage area.
• Keep the antenna away from metal ducts such as canalization, air-conditioning.
• Bear in mind that other wireless devices (such as telephones, microwaves, etc.) can temporarily interfere with the
quality of the wireless signal.
• We do not recommend that you install antennas in racks containing communication devices, computers, etc. Use
an extension cord for this and place the antenna outside.
The following recommendations are applicable to all wireless devices:
• Do not touch or move the antenna while the device is transmitting or receiving.
• When the antenna is transmitting, do not touch any equipment that contains devices that radiate very close to, or
touching, any exposed part of the body (particularly face and eyes).
• Do not install the device in areas where the atmosphere is potentially explosive.
• Wireless devices can cause interferences with other devices. Do not use the device in environments where medic-
al equipment is installed.
• To ensure the R&TTE 1999/5/EC directive is complied with, the device must be at least 15 cm away from a per-
son’s body when operating.
3.6 Installing the SIM card
A SIM card needs to be inserted in the Teldat 4Ge so the WWAN interface operates correctly. The router is
equipped with an external tray for SIM cards.
When inserting the SIM card, make sure you are protected against electrostatic discharges (ESD).
Warning
Do not touch the SIM card connector.
