The following emphases are used in this manual with the following meanings:

NOTE apply to technical requirements which the user of the equipment must particularly take into account to ensure a faultless function of the equipment/plant.

ATTENTION refers to instructions which have to be adhered exactly to avoid damage or destruction of the device.

CAUTION stand for instructions whose nonobservance doesn't exclude the endangering of persons.

At references to a component e.g. (figure 1/3) provided by a place number the reference to picture 1 place number 3 refers in this example.

2. Safety instructions Before taking the unit into operation please read the following safety precautions carefully! Important: The unit should only be opened by qualified persons. The unit must be disconnected from its power supply before service work is carried out. When the unit is open parts may be accessible through which dangerous voltages flow and with which contact may endanger your life. To guarantee the EMC protection of the amplifier the lid must be bold tight again after opening the amplifier.

Ambient temperature The ambient temperature should not exceed a range of 0 °C to +50 °C (32 °F to 122 °F). Humidity The unit may not be exposed to water drops or spray. If condensation is present, wait until the unit is dry before taking it into operation. Mains connection and mains cable By units with the power supply safety class I, the wire which is coloured green/yellow must be connected to the terminal in the plug marked with the letter "E" or by the earth symbol . The blue coloured wire must be connected to the terminal marked "N" and the brown coloured wire to the terminal marked "L". Units which operate with a remote feeding supply may not be connected to 230 VAC. To do so will endanger your life! At units with the power supply safety class II, the housing of the unit must be connected to ground at the place indicated in the operating instructions of the unit. The ground terminal of the plug is in the case not connected. Grounding of system According to EN 50 083 / VDE 0855 regulations, the antenna system must comply with the safety regulations e.g. grounding, potential equilization etc. Precautions to ensure the electro magnetic compability (EMV) All covers and screws must tightly be fitted and should be tightly fastened. Contact feathers should not be oxidated or deformed.

Any tampering can be dangerous and can perform the warranty invalid.

The modulator is powered with a voltage of 7.5VDC. The power supply voltage

must not exceed that otherwise the modulator could suffer irreparable damage and

subsequent invalidation of the warranty. Therefore:

Do not replace power supply with a voltage greater tan 7.5VDC. � Do not connect the modulator to the power if the power cord is damaged. � Do not plug the modulator into mains supply until all cables have been connected

correctly. � Do not cut the cord. • Modulator shall not be exposed to dripping or splashing water and no objects

filled with liquids, such as vases, shall be placed on it.

• Avoid placing modulator next to central heating components and in areas of high

humidity.

• Do not cover modulator elements that obstruct the ventilation slots and avoid

overheating.

• If the modulator has been kept in cold conditions for a long time, keep it in a warm

room no less than 2 hours before plugging into the mains.

• Mount the modulator in vertical position with the connectors located on the bottom

side.

• From top, front and bottom of installed modulator must be at least 10cm free

space.

Connect modulator to ground connection with terminal provided

(see point 5-B).

3. OPERATING ADJUSTMENTS

3.1 MODULATOR BOOT

When modulator is booting display shows firmware version during 2 seconds:

Next message shown is:“Booting…”

During that period of time the module is loading the firmware and initiating

internal devices.

Once started on the screen:

This message indicate modulator output channel, where XX is output channel (depends channel region selected ) and FFFFFF is frequency in kHz including

fine adjustment. Example:

*Output channel: C21 ( Western Europe ) with 25kHz of fine adjustment.

Note: switch menu language to English holding simultaneously down

buttons at power on. This operation can help you to restore bad

language configurations.
