Mounting the receiver into a 19 rack
Rack mounting
one receiver
To mount the receiver into a rack, you require the GA 3 rack adapter (optional accessory):
Secure the rack mount ears (supplied with the GA 3 rack adapter) to the receiver in
the same way as described for the stacking elements (see page 8).
Secure the blanking plate to one of the rack mount ears using two recessed head
screws (M 6x10) (see left-hand diagram).
Connect the antennas. There are two ways to connect the antennas:
You can connect the rod antennas to the rear of the receiver (see page 9). In this
case, insert the two blanking plugs into the holes of the blanking plate (see left-
hand diagram).
You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod
antennas to the front of the receiver (see right-hand diagram).
Slide the receiver with the mounted blanking plate into the 19 rack.
Secure the rack mount ears and the blanking plate to the 19 rack.
Do not mount the stacking elements and do not fit the rubber feet when rack moun-
ting the receiver.
CAUTION! Risks when rack mounting the receiver!
When installing the device in a closed or multi-rack assembly, please consider that, during
operation, the ambient temperature, the mechanical loading and the electrical potentials will
be different from those of devices which are not mounted into a rack.
Make sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the EM 100 G3 specifications.
Ensure sufficient ventilation; if necessary, provide additional ventilation.
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
When rack mounting, please note that intrinsically harmless leakage currents of the
individual mains units may accumulate, thereby exceeding the allowable limit value.
As a remedy, ground the rack via an additional ground connection.
When using more than one receiver, we recommend connecting remote antennas
and, if necessary, using Sennheiser antenna accessories. For more information, visit
the ew G3 product page at www.sennheiser.com.

Make sure that you set the transmitter to the same frequency bank and the same chan-
nel as the receiver.
For information on the setting options of the transmitter, refer to the instruction manual
of the transmitter.
You can also freely select the receiving frequencies and store these frequencies in the
frequency bank U.
If you want to use the frequency bank U:
Make sure to use receivers of the same frequency range (see page 4 and the type plate
of the receiver).
Only use frequencies that are approved and legal in your country (see page 19).
Set each receiver to the same frequency bank.
On one of the receivers, select a channel within this frequency bank (see page 18).
If you are using the frequency bank U, it might be that the receiving frequencies
are not intermodulation-free:
For possible frequency combinations, please refer to the frequency information
sheet or calculate the frequencies (see below).
To ensure that the desired frequencies are intermodulation-free, proceed as follows:
Calculate intermodulation-free frequencies using the Sennheiser Intermodula-
tion and Frequency Management (SIFM) software (see www.sennheiser.com).
Cleaning the receiver
21
Assign this channel one of the calculated receiving frequencies (see page 18).
Synchronize a transmitter with the receiver (see page 13)
OR
Manually set the transmitter to the same frequency bank, channel and frequency that
you set on the receiver.
Repeat for the remaining transmitters and receivers as described above.
Cleaning the receiver
Before cleaning, disconnect the device from the mains.
Use a slightly damp cloth to clean the receiver from time to time. Do not use any solvents
or cleansing agents.
If a problem occurs ...
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.
Keep all liquids away from the receiver.
