Using Cross Remote
The unit is equipped with a wireless remote control 
function that allows the unit’s settings (low-cut filter, 
attenuation controls, power controls, etc.) to be controlled 
from the receiver or other devices. This makes it easier to 
operate and manage the microphone system while in the 
field.
The IEEE802.15.4-compliant wireless remote control 
function uses the 2.4- GHz band and has no effect on the 
RF band of digital wireless audio.
The function is activated when the unit is paired with the 
receiver via the RF REMOTE function.
Pairing must be performed before the wireless remote 
control function can be used.
If “RESTRICTED BY GP/CH SETTING” appears on the 
RF REMOTE screen, the wireless remote control function 
cannot be used. To enable use of the wireless remote 
control function, select a different transmission channel.
For details on changing the transmission channel, see 
“Setting the Transmission Channel” (page 7).

devices.
• If pairing fails (i.e., “Pairing fail” is displayed), perform 
pairing again.
In such cases, communication between the transmitter 
and receiver may not have been established within the 
predetermined amount of time.
Pairing may be hindered if another receiver is engaged in 
pairing nearby.
• Unstable remote control may be resolved by disabling 
and reenabling the wireless remote control function in 
the RF REMOTE screen, then reestablishing connection 
with the transmitter (i.e., changing to a channel with less 
interference).

Finding the unit from a paired receiver
Some receivers are equipped with a function that finds the 
transmitters with which they are paired.
When this search function is used on a receiver that is 
paired with the unit, the unit’s organic EL display will 
blink.
If communication with the paired receiver is currently not 
possible, the unit’s organic EL display will not blink when 
the receiver’s search function is used.
For details, refer to the receiver’s operating instructions.
Using the Encrypted 
Transmission Function
The unit is capable of transmitting encrypted signals to 
prevent unwanted surveillance.
To use the function, select one of the following encryption 
modes.
Encryption key modes (SECURE KEY / AES256): 
An encryption key is automatically generated by the 
transmitter and used by both the transmitter and receiver in 
these one-to-one encrypted transmission modes.
The SECURE KEY mode is compatible with first and 
second generation DWX-series devices.
The AES256 mode uses AES 256-bit encryption for a 
higher level of security in transmissions.
Password mode (PASSWORD): A user-created 
password of up to 8 characters can be set for multiple 
transmitters (this unit) and receivers in this mode. This 
allows encrypted transmission within a group.
Make sure that encryption mode settings are identical on 
both the transmitter (this unit) and the receiver.
Using the Encryption Key Modes 
(SECURE KEY / AES256)
Use these modes for one-to-one encrypted transmission 
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.
1
Prepare the transmitter (this unit).
1Hold down the SET button in the unit’s 
ENCRYPTION screen until the setting value 
blinks.
2Use the + and – buttons to select SECURE KEY or 
AES256, and press the SET button.

instructions.
The unit searches for the receiver with which it is 
paired.
When the receiver is found, the encryption key is 
exchanged, and encrypted transmission begins.
Using the Password Mode (PASSWORD)
Use this mode for encrypted transmissions between 
multiple paired transmitters (this unit) and receivers.
When the same user-created password is set on both the 
transmitters (this unit) and the receivers, the audio signal 
can be decoded. This mode is useful when you want to 
operate multiple transmitters (this unit) and receivers as a 
group, or receive transmissions from a single transmitter 
(this unit) on multiple receivers at the same time.

Troubleshooting
If you encounter a problem when using the unit, check the following. If the problem persists, contact your Sony 
representative.
Symptom Cause Solution
Interruptions occur in the 
receiver audio.
The unit is too far from the receiver. Reduce the distance from the receiver, and 
check the reception.
The transmission power setting is set to “L: 2 
mW.”
Increase the transmission power (page 14).
There is no audio. The channel setting on the unit is different from 
that on the receiver.
Match the channel settings on the unit and 
receiver.
The encrypted transmission function settings on 
the receiver and transmitter do not match.
Match the encryption transmission function 
settings on the transmitter and receiver (page 9).
The audio codec mode settings on the receiver 
and transmitter do not match.
Match the audio codec mode settings on the 
receiver and transmitter (page 13).
The audio is weak. The audio input level on the unit is set to LINE, 
or the attenuator setting is too high.
If a microphone is connected, set the audio input 
level to MIC (page 13). In addition, set the 
attenuator to an appropriate level while 
monitoring the unit’s audio input level meter.
The audio is distorted. The attenuator is set too low for the audio input 
level of the unit.
Set the attenuator to a level that does not 
produce distortion while monitoring the unit’s 
audio input level meter.
There is no bass. The frequency of the low-cut filter is set too high. Decrease the low-cut filter frequency to a level 
that produces the proper sound quality while 
monitoring the audio (page 12).
There is too much bass. The bass of the connected microphone, for 
example, seem excessive, because the 
frequency response of the unit extends into the 
low 20-Hz range.
Use the low-cut filter function to cut the bass 
(page 12).
The unit does not turn off, 
even when the POWER 
button is held down.
Operation of the POWER button is locked. Set the LOCK function to UNLOCK (page 12).
Settings cannot be 
changed.
Changes to the settings are locked. Set the LOCK function to UNLOCK (page 12).

not possible.
Pairing has not been performed. Perform pairing (page 8).
The unit is too far from the receiver for 
communication to occur.
Check the condition indicator, and reduce the 
distance from the receiver if the level is low 
(page 4).
The transmitter that was paired with the receiver 
has been paired with another receiver.
On the receiver side, perform pairing with the 
transmitter you want to control again (page 8).
The display is too dark. The display brightness is set to low. Adjust the brightness of the display in the 
settings menu (page 15).
The LEDs are too dark. The LED brightness setting is set to DIMMER. Set the LED DIMMER setting to OFF (page 15).
The transmission power 
cannot be set.
The maximum transmission power setting may 
be limiting the transmission power setting.
Check the maximum transmission power setting, 
and adjust the setting accordingly.
The battery cannot be 
inserted into the unit.
The battery is oriented incorrectly. Check the orientation of the battery, and insert it 
until the lock lever locks into place (page 5).
The remaining battery 
indicator is incorrect.
The unit turns off 
immediately, even when the 
remaining charge is 
sufficient.
The unit does not turn on.
A battery other than the supplied NP-BX1 
rechargeable battery pack is being used.
Use the supplied NP-BX1 rechargeable battery 
pack.
The battery is not sufficiently charged. The battery will slowly discharge naturally, even 
when the unit is not used. Fully charge the 
battery.
If the remaining charge is not properly displayed 
after fully charging the battery, the battery may 
have reached the end of its life cycle. Use a new 
battery pack.

Important Notes on 
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.
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.
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.
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.
• Wipe the surface of the unit and its connectors using a 
soft, dry cloth. Never use chemicals, such as thinner, 
benzene, or alcohol, as they may damage the finish.
Notes on Simultaneous Multi-
Channel Operation
• 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 multi-
channel systems that includes both analog wireless and 
digital wireless devices.
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.
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.
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.
For details on updating the firmware on the DWX-series 
receiver or RMU-01 unit, contact your Sony 
representative.
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.

21

performance cannot be guaranteed and Sony will not be 
liable for any resulting damages.
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.
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 
capacity will gradually decrease as time passes and the 
battery is used. When the battery’s usable duration 
becomes drastically reduced, it may have reached the 
end of its life cycle. Purchase a new battery in such 
cases.
• The battery’s life cycle will vary depending on storage 
methods, usage conditions, and environments.
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.
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.
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.
