SAFETY INSTRUCTIONS
This device has been built and tested in accordance with the EU certifi cate of conformity and
left the factory in a safe condition. To retain this condition and to ensure hazard-free operation,
the user must pay attention to all instructions, warnings and warning markings.
1. The device may be operated only in the operating states and positions stated by the
manufacturer (ensure adequate ventilation). The following applies: IP protection class 22
(operation in the case), degree of soiling 2, overvoltage category 2.
The power supply unit may only be used indoors.
The satellite meter may be used outdoors at altitudes up to 2000 m above mean sea level
provided it is protected against rain and moisture. The power supply unit may be not be
operated on mains supplies with fuse ratings greater than 16 A. Unless stated otherwise
on the data sheet, a tolerance of ± 10 % applies to the mains voltage and a tolerance of
± 5 % to the mains frequency.
2. Where measurements are taken on circuits with voltages Ueff > 30 V, precautions
must be taken using suitable measures to exclude any hazard to persons (e.g. suitable
measuring equipment, fuse protection, current limitation, isolation, insulation, etc.).
3. Ensure by means of suitable overvoltage protection and earthing that the device cannot
be exposed to overvoltage (e.g. due to electrical storms). Otherwise there is a risk of
electric shock to the operating personnel.
Please follow the enclosed safety instructions.
For reasons of safety the MSK 120 must be returned to our Customer Service company
ESC for exchanging the built-in Lithium Polymer battery.
Please comply with the instructions in the appendix under “Service” and “Customer Service”.

GENERAL METHOD OF OPERATION
The Kathrein MSK 120 is a compact portable digital meter for Sat-IF reception systems. On the 5.7"
TFT screen, which is clearly visible in daylight, it is possible to display pictures from both SD (MPEG-2)
and HD (MPEG-4) channels. The integral CI interface enables even encrypted channels to be viewed 1).
All menus and measuring results are also shown on the display.
The device has been rigorously designed for use outdoors. A sturdy metal housing, operation via a sealed
membrane keypad, the use of a high quality lithium-polymer rechargeable battery and a robust protective
case make the MSK 120 suitable for everyday use.
Appropriate menu structures, data saving capabilities for several satellites and many channels make
operation extremely easy.
Due to the use of a high quality spectrum analyser, the integration of DiSEqCTM (incl. single-cable system
commands) and numerous measuring features such as level, BER, MER etc., the unit offers everything
you could ask for in daily use, both during the installation of Sat reception systems as well as during
troubleshooting.
1) In addition, an appropriate CA module and a smart card are necessary for decryption (not supplied).

Here the reception signal from the antenna system is fed in (coaxial socket F).
The remote power feed (for LNB) can be switched over from 14 VDC to 18 VDC. When the
LNB voltage is switched on the right-hand LED lights up green. This LED lights up red if there
is a short-circuit or overload. When an external voltage is applied, the LED lights up green.
Please make sure that
• no total voltage level higher than 122 dBμV,
• no positive DC voltage higher than 25 VDC,
• no negative DC voltage and
• no AC voltage
is applied to the SAT-IF input socket.
Failure to comply with these instructions can damage the input circuit.
The device can be operated on a mains power supply or its own built-in battery. The external
power supply is provided by the power supply unit and charger unit via the DC socket.
Use only the power supply unit that is supplied with the device.
The video and audio signal is available at the Scart socket on the front of the device for
evaluation on an external monitor. The settings menu also allows you to switch to audio/video
input. Incorrect wiring connections can damage the device!
An HD-capable screen can be connected via the HDMI socket.
The measurement results can be saved to a USB plugged into the USB port (USB 2.0).
A software update can also be performed using this port.

SET-UP
When setting up the device ensure that adequate ventilation is provided. To avoid the build-up of heat,
the case (display cover) must be opened. For continuous operation it is advisable to remove the case
completely.
MAINS OPERATION/BATTERY OPERATION
The device can be operated on a mains power supply or its own built-in battery.
The power supply unit supplied is suitable only for use with the MSK 120.
MAINS OPERATION
Take the supplied AC power supply unit (100 V...250 V) from its packaging and connect it to
the device and mains. The Li-polymer battery within the device now starts to be charged.
For mains operation use only the power supply unit supplied. The hollow plug of the power
supply unit is plugged into the socket on the front of the device.
When the device is not in use it should be connected to the mains power supply from time to
time (trickle charge).
BATTERY OPERATION
Battery operation is available only if the battery is suffi ciently charged. Otherwise the device
cannot be switched on.
If the battery becomes fully discharged it should be charged up again without delay. Charging
starts automatically as soon as the device is connected to the mains. The charging process
is controlled and monitored by the charge management function.
The device battery is fully charged before dispatch from the factory. Before your fi rst use the
device, fully charge the in-built battery once again.
To do this, connect the supplied AC/DC power supply unit to the mains and then plug the
hollow plug into the satellite meter.
The yellow charging indicator LED (“Charge”) lights up to indicate charging.
The charging process starting from a fully discharged battery takes about 4 hours if the
satellite meter is in operation, or about 2 hours if it is switched off. Once charging has been
completed, the charging indicator LED goes out.
