The procedure is the same as for the EK 100 G3 diversity receiver: To insert the batteries/accupack: Read the chapter Inserting the batteries/accupack on page 10. To charge the accupack: Read the chapter Charging the accupack on page 10.
Connecting the microphone cable/line cable
The audio input is designed for the connection of condenser microphones. DC powering of the condenser microphones is via the audio input MIC/LINE (3.5 mm jack socket). Use one of the recommended Sennheiser microphones or the optional CL 2 line cable. Connect the 3.5 mm jack plug from the Sennheiser cable to the 3.5 mm jack socket MIC/LINE.
Lock the 3.5 mm jack plug by screwing down the coupling ring of the cable. Via the operating menu, adjust the sensitivity of the microphone/line input.
Attaching and positioning the corresponding microphones
ME 2/ME 4 Use the microphone clip to attach the microphone to clothing (e.g. tie, lapel). The ME 2 clip-on microphone (shown on the right in the diagram) has an omni-directional pick-up pattern. It is therefore not necessary to position it precisely. Attach the ME 2 microphone as close as possible to the sound source.
The ME 4 clip-on microphone (shown on the left in the diagram) has a cardioid pick-up pattern. Position the ME 4 microphone so that its sound inlet is directed towards the sound source (e.g. mouth).

Synchronizing transmitters with diversity receivers
When synchronizing transmitters with diversity receivers, please observe the following: Make sure that the desired frequencies are listed in the enclosed frequency information sheet. OR: Contact your Sennheiser partner who will be pleased to calculate intermodulation-free frequencies for you. Make sure that the desired frequencies are approved and legal in your country and, if necessary, apply for an operating license. Upon delivery, transmitter and diversity receiver are synchronized with each other. If, however, you cannot establish a transmission link between transmitter and diversity receiver, you have to synchronize the channels of the devices: Deactivate the RF signal on all transmitters (see page 21). This prevents that, during the frequency scan, the channels used by switched-on transmitters are displayed as used. With a diversity receiver, perform a frequency preset scan to scan the frequency banks for unused channels (Scan New List, see page 24). Select a frequency bank and a channel on this diversity receiver (Current List, see page 24). If you want to set up a multi-channel system, select a frequency bank with a sufficient number of unused channels for all planned transmission links. Synchronize a transmitter with the diversity receiver (see page 19). The receivers frequency, name and pilot tone setting are transferred to the transmitter. OR: Manually set the transmitter to the same frequency bank and channel that you set on the receiver. Activate the RF signal on the transmitter. The transmission link is established. If you want to set up a multi-channel system: Repeat the following 4 steps for each additional transmission link: Perform a frequency preset scan with the next diversity receiver. Select a channel from the same frequency bank as with the first diversity receiver. Synchronize a transmitter with the diversity receiver. Activate the RF signal on the transmitter.

ew 100 P G3 Set _529660_0309_Sp9.book Seite 27 Mittwoch, 8. April 2009 6:57 18
Using freely selectable frequencies
You can also freely select the receiving frequencies and store these frequencies in the frequency banks U. It might be that the freely selected frequencies are not intermodulation-free If you use frequencies from the frequency bank U, it might be that the frequencies are not intermodulation-free. Contact your Sennheiser partner who will be pleased to calculate intermodulation-free frequencies for you (see www.sennheiser.com). Set each diversity receiver to the frequency bank U. On one of the receivers, select a channel within this frequency bank and assign this channel one of the calculated receiving frequencies (Tune, see page 24). Synchronize a transmitter with this receiver (see page 19). OR: Manually set the transmitter to the same frequency bank and channel that you set on the receiver. Repeat for the remaining transmitters and receivers as described above.
