CAUTION!
Danger of hearing damage!
If you switch the squelch off or adjust the squelch
threshold to a very low value, loud hissing noise can occur
in the receiver. The hissing noise can be loud enough to
cause hearing damage!
̈ Always make sure that the squelch is switched on.
̈ Before adjusting the squelch threshold, set the
volume of the headphone output PHONES to the
minimum (see page 21)
.
̈ Never change the squelch threshold during a live
transmission.
̈ Adjust the squelch threshold – with the transmitter switched off – to
the lowest possible setting that suppresses hissing noise.
A high squelch threshold reduces the transmission range.
The squelch should only be switched off for servicing purposes. With the
squelch threshold set to “5 dB”, you switch the squelch off by keeping the

The transmitter adds an inaudible signal, known as the pilot tone, to the
transmitted signal. The diversity receiver detects and evaluates the pilot
tone.
The pilot tone supports the diversity receiver’s squelch function, thus
protecting against interference due to RF signals from other devices.

Synchronizing a transmitter with the receiver
Synchronizing a transmitter with the
receiver
When synchronizing a transmitter with a diversity receiver, please
observe the following:
̈ Only use a transmitter and a diversity receiver from the same
frequency range (see the type plates on the transmitter and
the diversity receiver).
̈ Make sure that the desired frequencies are listed in the
enclosed frequency information sheet.
You can also 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 the instruction manual
of the transmitter).
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 23).
̈ Select a frequency bank and a channel on this diversity receiver
(“Current List”, see page 22).
If you want to set up a multi-channel system, select a frequency bank
with a sufficient number of unused channels for all planned transmis-
sion links.
Via the “Sync Settings” submenu, you can set additional transmitter
parameters directly on the diversity receiver and activate or deactivate
the transfer of these parameters to the transmitter (see page 28).
̈ Synchronize a transmitter with the diversity receiver (see page 19).
The receiver’s frequency, name, pilot tone setting and, where applies,
additional parameters activated via the “Sync Settings” submenu are
transferred to the transmitter.
30
Synchronizing a transmitter with the receiver
OR:
̈ Manually set the transmitter to the same frequency bank and channel
that you set on the receiver.
̈ Activate the RF signal on this 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.
Using freely selectable receiving frequencies
You can also freely select the receiving frequencies and store these
frequencies in the frequency banks “U1” to “U6”.
It might be that the freely selected frequencies are not inter-
modulation-free
If you are using frequencies from the frequency banks “U1” to
“U6”, it might be that the receiving frequencies are not intermod-
ulation-free.
̈ Contact your Sennheiser partner who will be pleased to
calculate intermodulation-free frequencies for you (see
̈ Set each diversity receiver to the same frequency bank (“U1” to “U6”).
̈ On one of the receivers, select a channel within this frequency bank and
assign this channel a receiving frequency (see page 25).
̈ Synchronize a transmitter with this receiver (see the instruction
manual of the transmitter).
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.
31
Cleaning the diversity receiver
Cleaning the diversity receiver
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.
̈ Do not use any solvents or cleansing agents.
̈ Use a cloth to clean the diversity receiver from time to time.
32
Recommendations and tips
Recommendations and tips
... for the diversity receiver
• Make sure that the antenna and the headphone or line cable do not
cross.
• For best results, make sure that the transmitter 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.
... for multi-channel operation
• When operating a multi-channel system, you should only use the chan-
nels within one frequency bank. Each of the frequency banks “1” to
“20” accommodates factory-preset frequencies which are intermodu-
lation-free.
• The frequency banks “U1” to “U6” allow you to freely select and store
receiving frequencies (see page 25).
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
