Using the
Wireless Remote
Control Function
This transmitter is equipped with a wireless
remote control function that can be used to
set the parameters (low-cut filter,
attenuation operation, power save mode,
etc.) of the transmitter through the receiver
or other devices. This function makes it
easier to operate and manage the
microphone system while in the field.
This wireless control is 2.4 GHz
IEEE802.15.4 compliant and has no effect
on the RF band of digital wireless audio.
This function is activated when pairing is
established between the transmitter and the
receiver using the RF REMOTE function.
Pairing must be done first before the
wireless remote control function can be
used.
Pairing with a receiver
Pairing links the transmitter with the
receiver which the wireless remote control
function is to be used.
When the transmitter has been paired with a
receiver through the receiver operation,
turning on the transmitter while holding
down the – button establishes the pairing
immediately.
To carry out pairing through menu
operations on the transmitter, do the
following.
1Set the receiver to be used for
controlling the transmitter to pairing
mode.
For details on receiver operations, refer to the
operating instructions supplied with the
receiver.
2Press the + or – button repeatedly until
the RF REMOTE indication is
displayed.
3Hold down the SET button until the
item to be set flashes.
4Press the + or – button repeatedly to
select PAIRING.
5Press the SET button to enter.
The transmitter sends a pairing request
to the receiver which is on pairing
mode.
Before established pairing, if you press
any operation key on the transmitter,
pairing mode will be cancelled.
When pairing has been established, the
wireless remote control condition level
(indicated by ) goes up, the RF
REMOTE function turns on, and the
remote control function becomes
operative.
To use the wireless remote
control function with a
previous pairing
In the RF REMOTE indication, select ON.
• When you set RF REMOTE to ON, the
transmitter will communicate with the
receiver to which it was previously
paired. To use the wireless remote
control function with another receiver,
you must perform the pairing procedure
for that receiver.
• Multiple transmitters cannot be paired
with the same receiver.
The following transmitter settings
can be done from the wireless
remote control:
• Group/channel/BAND setting
• RF transmission power setting
• Attenuator for the audio input setting
• Low-cut filter setting
• Power save setting
• +48 V power supply setting
For details on menu operation, see “Setting Menus”.
To cancel the wireless remote
control function
In the RF REMOTE indication, select OFF.
Notes on the wireless remote
control function
The wireless remote control function on the
transmitter uses the 2.4-GHz band and may
thus be subject to interference from other
devices.
• When pairing fails (“Pairing fail” is
displayed), successful communication
between the transmitter and the receiver
has not occurred within a given amount
of time. Pairing may be harder to do
when another receiver is engaged in
pairing nearby.
• When it becomes hard to use the remote
control, the remote control may be
improved by switching the wireless
remote control function off, then on again
in the RF REMOTE indication, then re-
pairing with the transmitter (change to a
channel with less interference).
Notes
Using the
Encrypted
Transmission
Function
To prevent hacking of the signal, the
transmitter scrambles the signal during
transmission. To use this function, select
one of the following encrypted transmission
modes:
Secure key mode: An encryption key
that is automatically generated by the
transmitter is used by both the transmitter
and receiver in this one-to-one encrypted
transmission method.
Password mode: You choose a
password of up to eight characters that can
be set for multiple transmitters and
receivers. This enables encrypted
transmission within a group.
Make sure the same mode is set on the
transmitter and receiver.
Using secure key mode
(SECURE KEY)
Use this mode for one-to-one encrypted
transmission between one transmitter and
one receiver.
An encryption key that cannot be read from
the outside is automatically generated by
the transmitter. This key is transmitted to
the receiver through a USB connection or
the RF REMOTE function, enabling
encrypted transmission to take place.
The encryption key used by the transmitter
and receiver is newly generated for each
key transmission, resulting in highly secure
communication.
The encryption key used between the
transmitter and the receiver is saved when
the power is turned off, so the encrypted
transmission can be resumed the next time
the power is turned on.

transmission function on the
receiver is different from that on
the transmitter.
Confirm that the setting of the
encrypted transmission function is
the same on both the transmitter
and the receiver.
The sound is
weak.
The audio input level of the
transmitter is set to LINE or the
attenuation level is too high.
If a microphone is connected to
the transmitter, set the audio input
to MIC. While monitoring the audio
input level meter, set the
attenuator to an appropriate level.
There is
distortion in the
sound.
The attenuator is set too low for
the audio input level of the
transmitter.
While monitoring the audio input
level meter, set the attenuator to a
level that does not produce
distortion.
The bass is
weak.
The frequency of the low-cut
filter is set too high.
While monitoring the sound,
decrease the low-cut filter
frequency to a level that produces
the proper sound quality.
There is too
much bass.
The microphone connected to
the transmitter produces
excessive bass because the
frequency response of the
transmitter extends into the low
20-Hz range.
Use the low-cut filter to cut the
bass.

Important Notes
on Operation
Notes on using the
transmitter
• The digital wireless microphone system
product must be used within a
temperature range of 0°C to 50°C (32°F
to 122°F).
• Operating the transmitter near electrical
equipment (motors, transformers, or
dimmers) may cause it to be affected by
electromagnetic induction. Keep the
transmitter as far from such equipment as
possible.
• The presence of the lighting equipment
may produce electrical interference over
the entire frequency range. Position the
transmitter so that interference is
minimized.
• To avoid degradation of the signal-to-
noise ratio, do not use the transmitter in
noisy places or in locations subject to
vibration, such as the following:
- near electrical equipment, such as
motors, transformers or dimmers
- near air conditioning equipment or
places subject to direct air flow from
an air conditioner
- near public address loudspeakers
- where adjacent equipment might
knock against the tuner
Keep the transmitter as far from such
equipment as possible or use buffering
material.
On cleaning
• If the transmitter is used in a very humid
or dusty place or in a place subject to an
active gas, clean its surface as well as the
connectors with a dry, soft cloth soon
after use. Lengthy use of the transmitter
in such places or not cleaning it after its
use in such places may shorten its life.
• Clean the surface and the connectors of
the transmitter with a dry, soft cloth.
Never use thinner, benzene, alcohol or
any other chemicals, since these may mar
the finish.
Notes on simultaneous multi-
channel operation
• Keep the transmitter at least 30
centimeters (11 7/8inches) away from
another transmitter.
• When only digital wireless microphones
are being used, keep the transmitter at
least 4 meters (13 feet) away from the
antenna of a receiver for up to 10
channels, and at least 6 meters (20 feet)
away for 11 or more channels.
• When a mixture of digital and analog
wireless microphones is being used, keep
the transmitter at least 6 meters (20 feet)
away from the antenna of a receiver.
• This system should be kept at least 100
meters (328 feet) away from any analog
wireless systems using the same
frequency when both are being used in a
wide area with no walls or obstructions.
• If you experience noise, increase the
distance between the transmitter and
receiver or decrease the transmission
power on the transmitter.
Note on microphone and
transmitter combinations
It is recommended that you use the Sony
ECM-673/674/678 Electret Condenser
Microphone with this transmitter. The
transmission signal may cause noise on
some microphones. If you experience noise,
you may be able to reduce it by lowering the
transmission power. Specifications
