Battery level indicator
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 TYPE 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 TYPE
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.
For details on the BATTERY TYPE function setting, see
“Setting the battery type (BATTERY TYPE)” (page 25).
Battery precautions
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.
• Batteries cannot be charged with this unit.
• 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.
Supplying power from a USB
connector
The transmitter (UTX-B40/P40) and tuner (URX-P40)
can operate from a commercially available USB-output
type AC adaptor or portable power supply connected to
the USB connector.
When supplying power using a USB-output type AC
adaptor or portable power supply, use a unit that satisfies
the following conditions.
• Output connector: USB type C
• Rated voltage: 5 V
• Output current: 200 mA or higher
Displays “USB” when power is supplied from the USB
connector.
• The UTX-M40 hand-held microphone cannot be
supplied using a USB connector.
• Noise may occur in the audio depending on the AC
adaptor 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 adaptor or
portable power supply or otherwise altering their
positions.
• If a USB Type C adaptor (from a different connector
type) or a cable that does not comply with the USB
Type C standard is used, noise may occur or power may
not be applied correctly. Always use cables that comply
with the USB Type C standard.
