NOTICE
Interference with electronic equipment caused by radio-
frequency energy.
Do not use the device with damaged cables or plugs.
•
Cables and plugs must always be shielded.
Observe all special regulations and disconnect the power
•
supply to the TFX if its use is prohibited or if you have
doubts as to whether operation can cause interference
or dangers.
NOTICE
Property damage.
The device must be installed, connected, and
•
commissioned by a quali ed technician.
Disconnect the device completely before handling it.
•
Also disconnect any independently supplied output
•
load circuits.
Provide all the device connectors with plugs and any
•
protection caps required to ensure protection class IP6K7 .
Only install the device in the installation position shown
•
in chapter Mounting the device.
Never immerse the device in water or other liquids.
•
The device must only be repaired by the manufacturer.
•
Keep substances that contain solvents away from the
•
type label.
Pay attention that all plug and cable connections are

made with the connectors correctly aligned and without
the use of excessive force.

2.2 CE notes

The devices described in this device manual may only
be used in mobile or stationary systems in which the
distance between antennas and persons is at least 20 cm.
Furthermore, antennas may only be operated if the correct
horizontal distance between them and other antennas or
transmitters is observed.
NOTICE
Loss of CE conformity is possible.
Only use antennas with a maximum gain of:
TFX External Antenna:
2.9 dBi (900 MHz, GSM 900 band / UMTS FDD-8 band)
7 .8 dBi (1800 MHz, GSM 1800 band)
11.8 dBi (2100 MHz, UMTS FDD-1 band)
TFX INSTALLATION AND OPERATION MANUAL
Changes or modi cations to this device not expressly
approved by the manufacturer can void the user's authority
to operate the device under CE rules.
INFORMATION
The horizontal distance between antennas can be calculated
for every radio signal.
The distance between two antennas should always be
greater than 1/4 of the wavelength, but not a multiple of the
wavelength. If you use several antennas with di erent radio
signals from each other, the distance of the antenna with
the lowest frequency range must be observed.
GNSS:
Frequency range 1.227 GHz, wavelength 33.33 cm
(1/4 = 6.11 cm)

2.3 FCC notes

The devices described in this device manual may only be
used in mobile or stationary systems in which the distance
between antennas and persons is at least 20 cm. The
antennas must further not be co-located or operated in
conjunction with any other antennas or transmitters.
NOTICE
This device has been tested and found to comply with the
limits for a Class B digital device pursuant to part 15 of the
FCC rules. These limits are designed to provide adequate
protection against harmful interference in a residential
installation. This device generates, uses, and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause interference
to radio communications. There is no guarantee that
interference will not occur in a particular installation. If
this device does cause interference to radio or television
reception, which can be determined by switching the
device on and o , the user is advised to try to correct the
interference by one or more of the following measures:
Realign the receiving antenna or put it in a di erent place.
•
Increase the distance between the device and
•
the receiver.
Connect the device and the receiver to di erent
•
supply circuits.
Consult the dealer or an experienced radio/TV technician
•
for help.
