Soldering Instructions
1. Soldering temperature should be controlled under 320 and soldering time for each terminal should be 1~2 sec..
2. Microphone should be fixed on the metal block (heat sink), which has high radiation effects, and heat sink shall contact with MIC tightly.
3. Microphone may easily be destroyed by the static electricity. All countermeasure for eliminating static electricity must be executed (worktable
and human body shall be ground connection)

Testing Procedure
1. Measure the microphones under standard operating condition.
2. Put the microphone and standard microphone face to the sound source (speaker),
the distance between sound source and microphone & standard microphone is
50cm. And keep the center distance 5cm between them to ensure that the change
of sound pressure should be kept within ± 1dB.
3. Keep the sound source pressure within ± 1dB from speaker Measured by standard
microphone.
