GENERAL
A
This section is extracted
from instruction manual.
Installing the battery (See fig. A)
1 Open the battery compartment lid.
2 Place the CR2025 battery (not supplied) with the + side facing upward.
Be sure to place the battery with polarity positioned correctly.

Battery life
The Sony CR2025 lithium battery (not supplied) gives continuous operation on the
microphone for about 350 hours. When you turn the power on, the battery check
indicator lights momentarily. When the battery becomes weak, the indicator lights
dimly or does not light at all. In this case, replace the battery with a new one. (Sony
CR2025 lithium battery (not supplied)). To avoid battery wear or leakage, be sure to
turn the power off after using the microphone.

When the battery compartment lid comes off
1 Hold down part A with a thumb so that it does not slide.
2 Insert one of the parts of A into the projecting part B of the battery compartment
and then insert the other part while pressing toward the inside.
Removing the battery (See fig. B)
When to replace the battery
When the power is turned on, the battery check indicator lights momentarily. When
the battery become weak, the indicator remains dimly lit or does not light at all. In this
case, replace the battery with Sony CR2025 lithium battery. Use of another battery may
present a risk of fire or explosion.
Under normal conditions of use, the battery will last approximately 350 hours.
Notes on lithium battery
• Keep the lithium battery out of the reach of children. Should the battery be
swallowed, immediately consult a doctor.
• Wipe the battery with a dry cloth to assure good contact.
• Be sure to observe the correct polarity when installing the battery.
• Do not hold the battery with metallic tweezers. Doing so can cause a short-circuit.

WARNING
Battery may explode if mistreated.
Do not recharge, disassemble or dispose of in fire.

Parts Identification and Uses (See fig. D)
1 Directive angle switch
Set the switch according to the sound source.
90˚: Use to pick up a relatively narrower sound source (instrumental solo,
conversation, etc.), to provide a clear stereo sound image focused on target
source.
120˚: Use to pick up a relatively wider sound source (orchestra, chorus, stage
play, etc.), to provide a natural stereo sound image with full reality.

The above are guidelines for selecting an appropriate angle. Although following
these guidelines is encouraged, you can freely select either angle according to
your own preference.
Note
If you switch the angle during recording, noise may occure.
2 Gold-plated triple-pole stereo miniplug
Connect to the MIC jack of your recording equipment (video camera, etc.)
3 Battery compartment lid
4 Power switch
ON: Select when the microphone works with the battery.
OFF: Select when the microphone works with plug-in power or when you turn it
off.

5 Battery check indicator
When the power is turned on, this indicator lights momentarily. When the battery
becomes weak, the indicator remains dimly lit or does not light at all. In this case,
replace the battery with a new one.
