To install a battery, first unscrew the bottom metal sleeve by turning it
counter-clockwise while holding the upper barrel of the microphone still.
Pull the bottom sleeve down to uncover the battery compartment and stop
when you feel resistance (the sleeve will remain attached). Insert a new
AA battery, matching the polarity indicated on the battery compartment.
Once the battery is installed, push the bottom sleeve back up and screw
clockwise to tighten. Tightening should be smooth and easy. Do not force
the sleeve as you tighten or you may damage the threads.
Power Switch
BATT ON: Turn the switch to this position when using battery power.
OFF / 48V: Turn the switch to this position when using phantom power and/or
not using the microphone. (If the switch is left in the “BATT ON” position, it will
keep drawing power from the battery.)
Low-Cut Switch
Flat position (low-cut filter off)
Low-cut filter on
* Do not operate the low-cut switch while recording as doing so may cause noise.
LED Battery Indicator
When the power switch is turned to “BATT ON”
• LED comes on briefly and turns off: The battery has sufficient power.
• LED comes on blinking: The battery has low power.
• LED does not come on: Either there is no battery installed or the battery is
dead.
Typical total battery life with the SGM-250 is 100 hours. When the LED blinks,
the battery will have about 10 hours of use remaining, however, audio quality
will soon start to diminish. It is recommended that you change the battery once
you see a blinking LED.
