Putting the receiver into operation Putting the receiver into operation Setting up the receiver on a flat surface Do not fit the device feet when mounting the receiver into a 19” rack. 왘 Clean the base of the receiver where you want to fix the device feet. 왘 Fit the device feet to the four corners of the receiver. 왘 Place the receiver on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces. 왘 Connect the antennas (see page 9).
Putting the receiver into operation CAUTION! Danger of short-circuit due to uninsulated antennas! An 11 V voltage is applied to the antennas – even when you switch the receiver off! If uninsulated antennas come into contact with objects which conduct electricity, this voltage can produce sparking and audio interference. 왘 Use insulated antennas. OR 왘 Always mount uninsulated antennas so that they cannot come into contact with objects which conduct electricity.
Putting the receiver into operation Mounting the antennas to the front of the rack To mount the antenna connections to the front of the rack when rack mounting the receiver, you require the GA 3030 AM antenna front mount kit (optional accessory). The GA 3030 AM consists of: • 2 BNC extension cables (screw-in BNC socket 씏 to BNC connector 씏 • 2 antenna holders ), , • 4 screws, • 2 washers 4 • 2 nuts , . 1 쐃 1 씏 쐃 씏 왘 Guide the two BNC connectors through the holes in the rack mount “ears” 쐃.
Putting the receiver into operation 왘 Connect the rod antennas to the BNC sockets 씏. 씏 Daisy-chaining receivers The receivers feature an integrated antenna splitter so that up to 10 receivers can be daisychained without any additional antenna splitters being required. Only daisy-chain receivers from the same frequency range (see page 4).
Putting the receiver into operation Connecting the mains cable CAUTION! Damage due to electric current! If you connect the receiver to an unsuitable power supply, this can cause damage to the device. 왘 Use the supplied mains cable to connect the receiver to the mains (100 to 240 V AC, 50 or 60 Hz). 왘 Ensure a reliable mains ground connection of the receiver – especially when you are using multi-outlet power strips or extension cables. 왘 Pass the mains cable through the cable grip 쐅.
Using the receiver Using the receiver To establish a transmission link, proceed as follows: 1. Switch the receiver on (see next section). 2. Switch the transmitter on (see the instruction manual of the transmitter). The transmission link is established and the display backlighting of the receiver changes from red to orange. It is vital to observe the notes on frequency selection on page 31.
Using the receiver Synchronizing a transmitter with the receiver You can synchronize a suitable transmitter of the 2000 series with the receiver.
Using the receiver Muting the audio signal To mute the audio signal: 왘 When one of the standard displays is shown on the display panel, press the STANDBY button. “RX Mute On?” appears on the display panel. 왘 Press the jog dial.

Synchronizing transmitters with receivers Synchronizing transmitters with receivers When synchronizing a transmitter with a receiver, please observe the following: 왘 Only use a transmitter and a receiver from the same frequency range (see the type plates on the transmitter and the receiver). 왘 Make sure that the desired frequencies are listed in the enclosed frequency information sheet.
Synchronizing transmitters with receivers 왘 Launch the “Wireless Systems Manager” (WSM) software. 왘 To scan for unused receiving frequencies and to configure the receivers, proceed as described in the instruction manual of the “Wireless Systems Manager” (WSM) software.
Cleaning the receiver Cleaning the receiver CAUTION! Liquids can damage the electronics of the receiver! Liquids entering the housing of the device can cause a short-circuit and damage the electronics. 왘 Keep all liquids away from the receiver. 왘 Do not use any solvents or cleansing agents. 왘 Before cleaning, disconnect the receiver from the mains. 왘 Use a cloth to clean the receiver from time to time.
Recommendations and tips Recommendations and tips ... for optimum reception • Transmission range depends to a large extent on location and can vary from about 10 m to about 150 m. There should be a “free line of sight” between transmitting and receiving antennas. • If, with the EM 2000 receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable.
If a problem occurs ... If a problem occurs ... Problem Possible cause Possible solution Receiver cannot be operated, “Locked” appears on the display panel Lock mode is activated Deactivate the lock mode (see page 15). No operation indication No mains connection Check the connections of the mains cable. No RF signal Transmitter and receiver are not on the same channel Set the transmitter and receiver to the same channel. To do so, use the synchronization function (see page 15).
If a problem occurs ... Problem Possible cause Possible solution None of the diversity Receiver’s squelch threshold is adjusted too Reduce the squelch threshold (see page 17). displays I or II appears on high the display panel Transmitter’s RF signal is too weak Increase the transmission power of the transmitter. Reduce the distance between transmitter and receiving antennas.
