Safety instructions

Never open electronic units! If units are opened by customers in breach
of this instruction, the warranty becomes null and void.

Keep the units away from central heating radiators and electric heaters.
Never expose them to direct sunlight.

Use the units in dry rooms only.

Use a damp cloth for cleaning the units. Do not use any cleansing agents
or solvents.

The freePORT systems

Designed for different areas of application, the freePORT systems are
available in three variants.

y Presentation Set:

This system is ideal for presentation applications. The unobtrusive
ME 2 clip-on microphone is virtually invisible.

y Instrument Set:

This system is for connecting musical instruments (e.g. guitar) which
have a ¼” (6.3 mm) jack socket directly to the bodypack transmitter.

y Vocal Set:

This system is ideal for vocal and speech applications.

Transmitters and receivers of the freePORT systems have four factory­preset frequencies for direct channel selection – ready for immediate
use after switch-on.

The freePORT systems are available in three UHF frequency ranges:

y Frequency range A: 719 to 721 MHz
y Frequency range C: 742.5 to 744.5 MHz
y Frequency range E: 863 to 865 MHz

Hinweise:

The Frequency ranges A and C can only be used in certain areas in
the EU and must be licensed with the regulating authorities. Fre­quency E is license-free in most EU countries (i.e. ETSI signatory
countries).

Please be legal and observe the country-specific regulations of the
licensing authorities. Sennheiser are not responsible if you operate
illegally.

To avoid interfering with other users, the transmitter should be
switched off when not in use.

Features of the freePORT systems:

y Up to four transmission links per frequency range which can be

operated simultaneously

y Reliable transmission technology
y Diversity technology for minimizing dropouts in the reception
y Adjustable squelch for eliminating RF interference
y Rugged housings
y Crystal-clear reception due to dynamic processor

왘 Connect the amplifier/mixing console to the XLR-3M socket  or

the ¼” (6.3 mm) jack socket .

왘 Use the GAIN control  to adapt the level of the audio output to the

input of the amplifier or mixing console. The adjusted audio output
level is common for both sockets. If the level is adjusted too high,
the audio signal will be distorted. If, on the other hand, the level is
adjusted too low, this will result in an audio signal with high
background noise.

Selecting and changing a channel

You can change the channel on the receiver during running operation.
The receiver then immediately receives on the new channel.

왘 Use a small screwdriver to set the channel selector switch  to the

desired channel. You can switch between four different channels
(see “Selecting a channel” on page 24).

Inserting/replacing the battery

We recommend powering the bodypack transmitter by a 9 V PP3
alkaline battery (IEC 6 LR 61). If powered by a rechargeable 9 V battery,
the operating time will be drastically reduced.

왘 Open the battery compartment by first sliding the battery

compartment cover in the direction of the arrow. Then flip the

battery compartment cover open.

왘 Insert the battery as shown. Please observe correct polarity when

inserting the battery.

왘 Close the battery compartment.

Note:

When the red LED  goes off during operation, you must replace

the battery as soon as possible.

Connecting the microphone/instrument cable

The audio input is designed for the connection of both the ME 2 clip-on
microphone and instruments (e.g. guitars).

왘 Connect the 3.5 mm jack plug from the microphone/instrument

cable to the 3.5 mm jack socket .

왘 Check the setting of the MIC/INST slide switch  which allows you

to switch between microphone and instrument operation. If
necessary, readjust the setting.

왘 Use the GAIN control  to adjust the transmitter sensitivity so that

the receiver receives a good audio signal (no distortion and no
background noise).

Attaching and positioning the microphone

Use the microphone clip to attach the ME 2 clip-on microphone to
clothing (e.g. tie, lapel). Conduct the microphone cable so that noise due
to friction is avoided and make sure that the antenna and the cable do
not cross. The omni-directional microphone picks up sound equally from
all directions. However, it should be attached as close as possible to the
sound source.

Attaching the bodypack transmitter to clothing

왘 Use the supplied belt clip  to attach the bodypack transmitter to

clothing. Make sure that the antenna is at least 1 cm away from the
body and is not kinked.

Switching the bodypack transmitter on/off

왘 Press the ON/OFF button  to switch the bodypack transmitter on

or off. If the bodypack transmitter is switched on, the red LED 
lights up.

Note:

Remove the battery when the transmitter will not be used for
extended periods of time.

Selecting and changing a channel

왘 Switch off the transmitter before you change the channel.
왘 Use a small screwdriver to set the channel selector switch  to the

desired channel. You can switch between four different channels.
When you switch on the bodypack transmitter again, it will transmit
on the new channel (see “Selecting a channel” on page 24).

왘 Close and lock the radio microphone.

Note:

When the red LED  goes off during operation, you must replace

the battery as soon as possible.

Switching the radio microphone on/off

왘 Use the ON/OFF switch  to switch the radio microphone on or off.

If the radio microphone is switched on, the red LED  lights up.

Note:

Remove the battery when the transmitter will not be used for
extended periods of time.

Selecting and changing a channel

왘 Switch off the radio microphone.
왘 Open the radio microphone (see “Inserting/replacing the battery”

on page 22).

왘 Use a small screwdriver to set the channel selector switch  to the

desired channel. You can switch between four different channels
(see “Selecting a channel” on page 24).

왘 Close and lock the radio microphone.
왘 Switch on the radio microphone again.

Sensitivity of the radio microphone

You can vary the bass reproduction by increasing/decreasing the
talking distance.

Setting up the system



Before starting transmission, do a soundcheck and set up the system as
follows:

Setting up the reception

The receiver’s four LEDs (RF LEVEL)  indicate the level of the received
RF signal. With the transmitter, walk up and down the transmission
area and check if the received RF signal is sufficient everywhere.
Reception is good if all four LEDs light up. Please observe the following:

y Transmission range depends to a large extent on location and can be

up to 100 m. Observe a minimum distance of 3 m between
transmitter and receiver. There should be a “free line of sight”
between transmitting and receiving antennas.

y Do not operate the system close to metal objects such as cross

members or reinforced-concrete walls. Computers or mobile phones
in direct proximity to the antenna will interfere with the reception.

y Each transmitter requires a receiver. When using several trans-

mission links simultaneously, make sure that all transmission links
operate on different channels.

23



Adjusting the squelch threshold

Interference due to other transmission links can be eliminated as
follows:

왘 Switch off the transmitter. The receiver should no longer receive a

signal.

왘 If the receiver still receives a signal, use the SQUELCH control  to

increase the squelch threshold so that the signal will no longer be

received. If the signal cannot be eliminated in this way, set the

transmitter and the receiver to a different channel.

왘 Switch on the transmitter again and check if the receiver receives

the transmitter signal.

Note:

If the squelch threshold is adjusted too high, the transmission range

will be reduced. Therefore, always adjust the squelch treshold to the

lowest possible setting.

Selecting a channel

Transmitters and receivers have four channels respectively with
intermodulation-free frequencies.

Note:

These frequencies are different to those in evolution systems and

freePORT systems should not be used together with evolution sys-

tems without great care.

24



왘 Always set the transmitter and the receiver to the same channel.

Adjusting the transmitter sensitivity



왘 Use the GAIN control  on the SK 2 bodypack transmitter to adjust

the sensitivity so that even during the loudest passages the

AF PEAK LED  on the EM 1 receiver does not light up.

Care and maintenance

Use a slightly damp cloth to clean the units from time to time.

Note:

Do not use any cleansing agents or solvents.

To clean the SKM 3’s sound inlet basket:

왘 Unscrew the sound inlet basket  (turn counterclockwise) and

remove it.

왘 Remove the foam insert and use a slightly damp cloth to clean the

sound inlet basket.

왘 Reinsert the dry foam insert, replace the sound inlet basket on the

SKM 3 and screw it tight.
