between one transmitter (this unit) and one receiver.
To enable encrypted transmission in these modes, an
encryption key that cannot be read from the outside is
automatically generated by the unit, and the key is
transmitted to the receiver via the wireless remote control
function.
A new encryption key for the transmitter (this unit) and
receiver is automatically generated for each key
transmission, resulting in highly secure communication.
The encryption key for the transmitter (this unit) and
receiver is retained when the unit is turned off, allowing
you to resume the same encrypted transmission the next
time you turn the unit on.

Important Notes on
Operation
Notes on Simultaneous MultiChannel Operation
The life expectancy of the electrolytic capacitor is about 5
years under normal operating temperatures and normal
usage (8 hours per day; 25 days per month).
If usage exceeds the above normal usage frequency, the
life expectancy may be reduced correspondingly.
• Keep transmitters at least 30 cm (11 7/8 in.) away from
each other.
If distances closer than the above between transmitters
cannot be avoided, use a grouping system for multichannel systems that includes both analog wireless and
digital wireless devices.
The battery terminal of this unit (the connector for battery
packs and AC adaptors) is a consumable part.
Power may not be supplied to the unit properly if the pins
of the battery terminal are bent or deformed by shock or
vibrations, or if they become corroded due to prolonged
outdoor use.
Periodic inspections are recommended to keep the unit
working properly and to prolong its usable lifetime.
Contact a Sony service or sales representative for more
information about inspections.
For details, refer to “Sony Digital Wireless Microphone
System Frequency Lists” on the supplied CD-ROM.
• Refer to the following when determining the distances
between the transmitters and the antennas of receivers.
When using only digital wireless devices:
• At least 4 m (13 ft.) (for up to 10 channels)
• At least 6 m (20 ft.) (for 11 or more channels)
When using a mixture of digital and analog
wireless devices:
At least 6 m (20 ft.)
• This system should be kept at least 100 m (328 ft.) 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 noise occurs, increase the distance between the
transmitter and receiver or decrease the transmission
power on the transmitter.
Operation and Storage
• The unit must be used within a temperature range of 0 °C
to 50 °C (32 °F to 122 °F).
• Using the unit near electrical equipment (motors,
transformers, or dimmers) may cause it to be affected by
electromagnetic induction. Keep the unit as far from
such equipment as possible.
• The presence of the lighting equipment, including
decorative lights, may produce electrical interference
over the entire frequency range. The interference will
vary depending on the positions of the receiving antenna
and wireless microphone, so position equipment so that
interference is minimized.
• When using the unit in locations with excessive noise or
vibration, the vibration may transfer directly to the unit,
resulting in the generation of electrical noise
(microphonics) and degradation of the signal-to-noise
ratio. To prevent such occurrences, avoid using the unit
in the following locations.
– Near motors, transformers, etc.
– Locations subject to noise and air flow from air
conditioning equipment
– Near PA (public address) system speakers
– Locations subject to knocks or contact from adjacent
equipment
In addition to keeping the unit as far from such
equipment as possible, use buffering materials or take
other preventative measures.
Notes on Use with Microphones
We recommend using the ECM-77LM lavelier
microphone with the unit. The unit’s transmission signal
may cause noise on other microphones. If noise occurs,
you may be able to reduce it by changing the position of
the microphone cable, moving the microphone connection
away from the antenna, or decreasing the transmission
power.
To prevent electromagnetic interference from portable
communication devices
The use of portable telephones and other communication
devices near the unit may result in malfunction and
interference with audio signals. It is recommended that
portable communication devices near the unit be turned off.
CROSS REMOTE Compatibility
As the unit supports a wider band than previous
transmitters, establishing wireless remote communication
via CROSS REMOTE between the unit and DWX-series
devices requires firmware update for the receiver and
RMU-01 unit.
Cleaning
• After using the unit in excessively humid or dusty
locations or in the presence of active gases, clean the
surface of the unit and its connectors as soon as possible.
Extended use in such locations or failure to clean may
shorten the life cycle of the unit.
For details on updating the firmware on the DWX-series
receiver or RMU-01 unit, contact your Sony
representative.

Notes on Drip Resistance
The unit is designed with a drip resistance equivalent to
IPX4/IPX5*. Water entering the inside of the unit may
result in fire, electric shock, or malfunction. Be sure to
read and understand the following precautions before use.
* IPX represents the degree ingress protection against
water. IPX4-equivalent specifications protect unit
functionality against splashes from all directions, while
IPX5-equivalent specifications protect against jets of
water from all directions.
Notes on Accessories
We recommend using Sony accessories with the unit.
When products from other manufacturers are used,
performance cannot be guaranteed and Sony will not be
liable for any resulting damages.
The unit’s drip resistance is based on testing by Sony with
the battery compartment cover completely closed and
locked and the antenna completely secured. Sony will not
be liable for any damages resulting from ingress due to
improper handling of the unit.
Notes on the Battery
Charge the battery in an ambient temperature range of
10 °C to 30 °C (50 °F to 86 °F). Efficient charging may not
be possible at other temperatures.
Ensuring drip resistance
Be sure to read the following precautions, and handle the
unit properly.
• The battery compartment cover is plays a vital role in
maintaining drip resistance. When using the unit, be sure
to lock the battery compartment cover securely and
check that it is completely closed. Drip resistance cannot
be maintained when foreign objects are caught between
the cover’s rubber packing and the surface the packing
meets. This may result malfunction due to ingress of
water into the battery compartment. In such cases,
remove the foreign objects with a soft cloth that does not
leave behind particles.
• The unit’s rubber packing may crack or deform over
extended use depending on the usage environment. We
recommend periodic inspections to ensure drip
resistance. For details, contact your Sony representative.
• The unit is not water resistant. Do not submerge the unit
in water, subject it to running faucet water, or otherwise
subject it to high water pressure.
• Drip resistance cannot be guaranteed if the unit is
dropped or otherwise subjected to strong shock. In such
cases, we recommend inspection or repair.
Battery usage
• Battery performance drops in low ambient temperatures,
resulting in shorter usable durations. To extend the usage
duration in low ambient temperatures, place the battery
in your pocket, for example, and insert it in the unit
immediately before use.
• The battery is not waterproof. Be careful not to wet the
battery.
• Do not leave the battery in high temperature
environments, such as inside a hot car or under direct
sunlight.
• If the battery terminals are dirty, problems, such as
power not being supplied or charging not being possible,
may occur. In such cases, wipe the battery terminals with
a dry cloth or cotton swab to remove the dirt.
Battery storage
• Even during extended periods of disuse, charge the
battery about once a year to maintain its functionality.
After charging the battery, insert it in the unit, use it until
it is completely discharged, and then remove it from the
unit before storing it in a cool location with low
humidity.
• To prevent dirtying of the terminals, short circuits, or
other problems, place the removed battery in a plastic
bag, for example, and keep it away from metal objects
during transport or storage.
Battery life cycle
• The battery is a consumable part. The battery’s charge
