The SKM 100 G3 radio microphone family
The SKM 100 G3 radio
microphone family
This radio microphone is part of the evolution wireless
series generation 3 (ew G3). With this series, Sennheiser
offers high-quality state-of-the-art RF transmission
systems with a high level of operational reliability and ease
of use. Transmitters and receivers permit wireless transmission with studio-quality sound.
Features of the evolution wireless 100 G3 series:
• Optimized PLL synthesizer and microprocessor
technology
• HDX noise reduction system
• Pilot tone squelch control
• True diversity technology
• Switching bandwidth of 42 MHz
• Increased immunity to intermodulation and
interferences in multi-channel operation
• Interchangeable microphone heads, allowing the use of
different pick-up patterns and sensitivities
The frequency bank system
The radio microphone is available in 6 UHF frequency
ranges with 1,680 transmission frequencies per frequency
range:
Range A: Range G: Range B: Range C: Range D: Range E:
516 – 558
566 – 608
626 – 668
Each frequency range (A–E, G) offers 21 frequency banks
with up to 12 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1 ... 20
Channel 12 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U
734 – 776
780 – 822
823 – 865
Channel 12 – freely selectable frequency
Each of the channels in the frequency banks “1” to “20”
has been factory-preset to a fixed frequency (frequency
preset).
The factory-preset frequencies within one frequency bank
are intermodulation-free. These frequencies cannot be
changed.
3
Page 5
The SKM 100 G3 radio microphone family
For an overview of the frequency presets, please refer to the
supplied frequency information sheet. Updated versions
of the frequency information sheet can be downloaded
from the SKM 100 G3 product page on our website at
www.sennheiser.com.
The frequency bank “U” allows you to freely select and
store frequencies. It might be that these frequencies are
not intermodulation-free.
Areas of application
The radio microphone can be combined with the EM 100 G3
rack-mount receiver.
The EM 100 G3 rack-mount receiver is available in the same
UHF frequency ranges and is equipped with the same
frequency bank system with factory-preset frequencies.
This has the advantage that
• a transmission system is ready for immediate use after
switch-on,
• several transmission systems can be operated simultaneously on the preset frequencies without causing
intermodulation interference.

Only hold the radio microphone by its body.
To establish a transmission link, proceed as follows:
1. Switch the receiver on
(see the instruction manual of the receiver).
2. Switch the radio microphone on (see next section).
The transmission link is established and the receiver’s
RF level display “RF” reacts.
It is vital to observe the notes on frequency

A special feature of the Sennheiser ew G3 series is the
consistent, intuitive menu structure of transmitters and
receivers. As a result, adjustments to the settings can be
made quickly – even in stressful situations, for example on
stage or during a live show or presentation.
Make use of the possibility to adjust settings via the
operating menu of the receiver and to transfer these
settings to the radio microphone.
For more information on how to transfer settings to
the radio microphone, refer to the instruction

The radio microphone adds an inaudible signal, known as
the pilot tone, to the transmitted signal. The receiver
detects and evaluates the pilot tone.
The pilot tone supports the receiver’s squelch function
(Squelch) and protects against interference due to
RF signals from other devices.
Devices of the ew 100 G1 series (generation 1) do not
support the pilot tone function. Therefore, please observe

devices from an earlier evolution wireless generation:

Synchronizing the radio microphone with a receiver
Synchronizing the radio
microphone with a receiver
When synchronizing the radio microphone with a receiver,
please observe the following:
Only use a transmitter and a receiver from the
same frequency range (see the type plate on the
transmitter and the receiver).
Make sure that the desired frequencies are listed
in the enclosed frequency information sheet.
Make sure that the desired frequencies are
approved and legal in your country and, if necessary, apply for an operating license.
Synchronizing the radio microphone with the receiver – individual operation
Upon delivery, the radio microphone and the receiver are
synchronized with each other.
If, however, you cannot establish a transmission link
between radio microphone and receiver, you have to
synchronize the channels of the devices.
For information on automatic synchronization of the radio
microphone with the receiver (individual operation), refer
to the instruction manual of the receiver. This information
is marked with the icon.
Alternatively, you can set the channel on the radio microphone manually:
Make sure that you set the radio microphone to the
same frequency bank and the same channel as the
receiver (see page 21).
If you still cannot establish a transmission link, refer to the
chapter “If a problem occurs ...” on page 28.
Synchronizing radio microphones with receivers – multi-channel operation
Combined with ew 100 G3 receivers, ew 100 G3 radio
microphones can form transmission links that can be used
in multi-channel systems.
For information on automatic synchronization of radio
microphones with receivers (multi-channel operation),
refer to the instruction manual of your receiver.
For more information on multi-channel operation, visit the
SKM 100 G3 product page at www.sennheiser.com.

Cleaning the radio microphone
Cleaning the radio microphone
CAUTION! Liquids can damage the electronics of the
radio microphone!
Liquids entering the housing of the device
can cause a short-circuit and damage the
electronics.
Keep all liquids away from the radio
microphone.
Use a cloth to clean the radio microphone from time to
time.
Do not use any solvents or cleansing agents.
To clean the sound inlet basket of the microphone head
(MMD 835-1, MMD 845-1, MME 865-1):
Unscrew the upper sound inlet basket from the micro-
phone head by turning it counterclockwise (see
diagram).
CAUTION! Liquids will damage the microphone module!
Liquids will damage the microphone module.
Only clean the upper sound inlet basket.
Remove the foam insert.
To clean the sound inlet basket:
– Use a cloth to clean the upper sound inlet basket from
the inside and outside.
OR
– Scrub with a brush and rinse with clear water.
If necessary, clean the foam insert with a mild detergent
or replace the foam insert.
Dry the upper sound inlet basket.
Dry the foam insert.
Reinsert the foam insert.
Replace the sound inlet basket on the microphone head
and screw it tight.
You should also clean the contact rings of the microphone
head from time to time:
Wipe the contact rings of the microphone head with a
cloth.

Recommendations and tips
Recommendations and tips
... for optimum sound
• Hold the radio microphone in the middle of the microphone body. Holding it close to the sound inlet basket
will influence the radio microphone’s pick-up pattern.
• You can vary the bass reproduction by increasing/
decreasing the talking distance.
• For best results, make sure that the sensitivity is
correctly adjusted.
... 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.
• To avoid overloading the receiver, observe a minimum
distance of 5 m between transmitting and receiving
antennas.
• Only hold the radio microphone by its body. If you
touch the antenna of the radio microphone, the transmission range will be considerably reduced.
... for multi-channel operation
• For multi-channel operation, you should only use the
channels within one frequency bank. Each of the
frequency banks “1” to “20” accommodates factorypreset frequencies which are intermodulation-free.
• When using several transmitters simultaneously,
interference can be avoided by maintaining a
minimum distance of 20 cm between two transmitters.
