Synchronizing Transmitters With Diversity Receivers (Sync); Using Freely Selectable Receiving Frequencies; Cleaning The Diversity Receiver; Recommendations And Tips - Sennheiser EK 300 IEM G3 Instruction Manual

Synchronizing an SR 300 IEM G3 transmitter with the diversity receiver
Start the Easy Setup Sync function by placing the infra-red interface of
this diversity receiver in front of the infra-red interfaces
mitters, one after the other.
¿
The diversity receiver transfers an unused channel from the selected
frequency bank to the first transmitter and the next unused channel to
the second transmitter and so on. As soon as a transfer is completed,
the display panel of the transmitter displays the numbers of the trans-
ferred frequency bank and channel.
Synchronizing transmitters with diversity receivers
(Sync)
In a second step, you transfer the frequency bank and channel settings
from the transmitters to other diversity receivers (synchronization) and
thus establish the transmission links.
If you want to carry out synchronization at a later time:
Press the jog dial on the transmitter.
The frequency bank and the channel are stored. The transmitter's
RF signal is activated again. You can synchronize this transmitter with
a diversity receiver at any time (see the instruction manual of the
transmitter).
To carry out synchronization immediately:
Start the Sync function by placing the infra-red interface of the first
diversity receiver in front of the infra-red interface
mitter while simultaneously pressing the
mitter.

The diversity receiver is set to the same frequency bank and channel as
the transmitter. The transmitter's RF signal is activated again. A trans-
mission link is established between the first transmitter and the first
diversity receiver.
Synchronize each of the remaining transmitters with one of the
remaining diversity receivers.
Your multi-channel monitoring system is now ready for operation.
Instead of synchronizing, you can manually set the transmitters to the
same frequency bank and channel that you set on the corresponding
diversity receivers.

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
www.sennheiser.com).
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 18).
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.

Cleaning the diversity receiver

CAUTION! Liquids can damage the electronics of the diversity
receiver!
Liquids entering the housing of the device can cause a
short-circuit and damage the electronics.
Keep all liquids away from the diversity receiver.
Do not use any solvents or cleansing agents.
Use a cloth to clean the diversity receiver from time to time.

Recommendations and tips

... for the diversity receiver
• Make sure that the antenna and the earphones 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 17).
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
