capacitiy of the battery is sufficient (ON).
Red LED is flashing:
The battery is going flat
(LOW BATT)!
Red LED lights up brightly: The transmitter is fully modulated (PEAK).
7
Preparing the transmitter for use
Inserting and changing the battery
For powering the transmitter, use a 1.5 V AA size alkaline-manganese
battery.
Open the battery compartment by
pushing the two catches in the
direction of the arrows and open the
cover .
Insert the battery as shown in the
diagram on the left. Please observe
correct polarity when inserting the
battery.
Close the battery compartment.
8
Connecting the microphone
The transmitter is designed for use with Sennheiser lavalier microphones
and headmics (-4 versions). The power supply of these microphones is via
the microphone input of the transmitter.
Connect the microphone to the microphone
input of the transmitter.
Screw down the coupling ring.
Connecting the antenna
The transmitter is supplied with a plug-on antenna.
Connect the antenna to the antenna socket of the transmitter.
Screw down the coupling ring.
9
Attaching the transmitter to clothing
The transmitter is attached to clothing (e.g.
belt, waistband) with the supplied belt clip.
The clip is detachable so that you can also
attach the transmitter with the antenna
pointing downwards. To do so, withdraw the
clip from its fixing points and attach it the
other way round.
Using the transmitter
Switching the transmitter on/off
Open the battery compartment.
To switch the transmitter on, briefly
press the ON/OFF button .
The red LED lights up normally and
the standard display is shown on the LC
display panel ; after a short pause,
“RF” appears on the LC display panel.
Note:
! Remove the battery when the transmitter will not be used for extended periods of time.
10
! The transmitter can only be switched off when the lock mode is
deactivated (see “The automatic lock mode (autolock function)” on
page 13).
To switch the transmitter off, press the
ON/OFF button until “OFF” appears on
the LC display panel .
The red LED and the LC display panel go
off.
Note:
! When in the setting mode of the operating menu, the ON/OFF button
will cancel your entry (ESC function).
Doing a frequency check
The transmitter has a frequency check mode that prevents the transmitter
transmitting on an unwanted frequency after switch-on.
W hen switching on the transmitter, keep
the ON/OFF button pressed.
The current frequency is displayed on the
LC display panel without the transmitter actually transmitting.
If the displayed frequency is the correct
RF
one, release the ON/OFF button .
After five seconds, “RF” appears on
the LC display panel and the transmitter
is transmitting.
MHz
To change the transmission frequency, proceed as follows:
Release the ON/OFF button .
Immediately (i.e. within five seconds) press the multi-function
switch (switch position SET) twice.
You are now in the setting mode of the “CHAN” or “TUNE” menu where
you can change the transmission frequency (see “Adjustment tips for
the operating menu” on page 21).

Adjustment tips for the operating menu
Selecting a channel – CHAN
Via the “CHAN” menu, you can switch between the channels in the channel
banks “FIX“ and “VAR“. The transmitter is not transmitting while this
adjustment is being made.
When changing to the setting mode of the “CHAN” menu, the current
channel number appears on the diplay. After approx. 1 second, the
currently assigned transmission frequency is displayed.

MHz
To select a different channel, slide the multi-function switch to the
position (UP) or (DOWN). The new channel number appears on the
display panel for approx. 1 second and then the currently assigned
transmission frequency is displayed.
Only after the new setting has been stored (“STOR ED” has appeared on
the LC display panel) does the transmitter operate on the transmission
frequency of the new channel.
Note:
The frequencies in the channel bank “FIX” can only be changed by a
Sennheiser Service Partner. If you require a special frequency set in this
bank, please contact your local Sennheiser Service Partner.
Selecting the frequencies to be stored in the channel
bank “VAR” – TUNE
Via the “TUNE” menu, you can freely select the frequencies to be stored in
the channel bank “VAR” (variable bank). The transmitter is not transmitting while this adjustment is being made.
Note:
When you have selected the channel bank “FIX” and then select the
“TUNE” menu, the transmitter automatically switches to channel 01 of
the channel bank “VAR” and “VAR” briefly appears on the LC display
panel .
21
The frequencies are tunable in 5-kHz steps within a switching bandwidth of
36 MHz max.
Note:
When operating a multi-channel system, make sure to only use intermodulation-free frequencies.
There are two options for setting the frequencies:

Adjusting the microphone sensitivity – ATTEN
Via the “ATTEN” menu, you can adjust the transmitter’s sensitivity.
RF
AF
dB
The sensitivity is correctly adjusted when the level
display for audio signal “AF” shows full
deflection only during the loudest passages or
when the redLED lights up brightly.
The sensitivity can be adjusted in 1-dB steps from
+ 40 dB to –30 dB.
Note:
! The bargraph has a resolution of approx. 3 dB
per segment with a display range of 45 dB.
Adjusting the bass roll-off frequency – LOWCUT
To reduce unwanted low-frequency noise such as wind and handling noise,
you can activate a low-cut filter. The low-cut frequency is 1 20 Hz.
If you do not want to reduce low-frequency signal portions, select the setting “FLAT”.

25
Adjusting the output power – POWER
Licensing regulations may require a limitation of the output power to
10 mW. The transmitter therefore features a switchable output power.
With reduced output power, the operating time increases.
Exiting the operating menu – EXIT
Via the “EXIT” menu, you can exit the operating menu and return to the
standard display.
When in the operating menu, briefly pressing the ON/OFF button will
cancel your entry (ESC function) and return you to the standard display
without saving any changes.

Tips for optimum reception
! Transmission range depends to a large extent on location and on the
selected output power. There should be a “free line of sight” between
transmitting and receiving antennas.
! To avoid overmodulating the receiver, observe a minimum distance of
5 m between transmitting and receiving antennas.
Tips for multi-channel operation
! When operating a multi-channel system, make sure to only use
intermodulation-free frequencies.

Manufacturer declarations
Warranty regulations
The guarantee period for this Sennheiser product is 24 months from the date of purchase.
Excluded are accessory items and disposable batteries that are delivered with the product; due to their characteristics these products have a shorter service life that is principally dependent on the individual frequency of use.
The guarantee period starts from the date of original purchase. For this reason, we recommend that the sales receipt be retained as proof of purchase. Without this proof (which
is checked by the responsible Sennheiser service partner) you will not be reimbursed for
any repairs that are carried out.
Depending on our choice, guarantee service comprises, free of charge, the removal of
material and manufacturing defects through repair or replacement of either individual
parts or the entire device. Inappropriate usage (e.g. operating faults, mechanical damages, incorrect operating voltage), wear and tear, force majeure and defects which were
known at the time of purchase are excluded from guarantee claims. The guarantee is void
if the product is manipulated by non-authorised persons or repair stations.
In the case of a claim under the terms of this guarantee, send the device, including accessories and sales receipt, to the responsible service partner. To minimise the risk of transport damage, we recommend that the original packaging is used. Your legal rights against
the seller, resulting from the contract of sale, are not affected by this guarantee.
The guarantee can be claimed in all countries outside the U.S. provided that no national
law limits our terms of guarantee.
