Press and hold the POWER/MUTING button to turn 
the power off.

Turn the grip in the direction of the arrow, and pull 
the grip down until the battery compartment is 
visible.

Insert two new AA batteries into the battery 
compartment with 3 and # polarities in the correct 
orientation.

Close the grip, turning it in the reverse direction of 
step 2.

Press and hold the POWER button for 1 second or longer 
to display the battery level on the display. 
Immediately replace both batteries with new batteries if 
the indicator starts flashing (indication 5 below). If using 
new alkaline batteries, use after checking the 
recommended time limits.

• When BATTERY is set to TYPE1, the battery level is 

indicated based on the use of new LR6 (size AA) Sony 
alkaline batteries. The battery level may not be 
displayed correctly when different kinds of batteries, 
different brand of batteries, or old batteries are used. If 
using batteries other than size AA alkaline batteries, 
select the battery type using the BATTERY function.

• If you plan to use the transmitter continuously for a long 

period of time, it is recommended that you replace the 
batteries with brand new ones.

• Battery power is gradually consumed, even when the 

unit is turned off. Remove the batteries from the unit 
before prolonged periods of disuse.

Batteries may leak or explode if mistreated. Be sure to 
follow these instructions.
• Insert batteries in the correct 3 and # polarity 

orientation.

• Always replace the two batteries together with new 

ones.

• Do not use different types of batteries or old and new 

ones together.

• Dry cells are not rechargeable.
• When not using the device for a long period of time, 

remove the batteries. If the batteries leak for any reason, 
consult your Sony service representative.

The transmitter (UTX-B03/P03) and tuner (URX-P03) 
can operate from a commercially available USB-output 
type AC adapter or portable power supply connected to 
the USB connector.
When supplying power using a USB-output type AC 
adapter or portable power supply, use a unit that satisfies 
the following conditions.
• Output connector: USB micro B type
• Rated voltage: 5 V
• Output current: 200 mA or higher

Displays “EXT” when power is supplied from the USB 
connector. 

• The UTX-M03 hand-held microphone cannot be 

supplied using a USB connector.

• Noise may occur in the audio depending on the AC 

adapter or portable power supply that is connected. In 
such cases, you can reduce the noise by distancing the 
unit or lavalier microphone from the AC adapter or 
portable power supply or otherwise altering their 
positions.
