Microphone Calibration: Note: If you purchased the complete IE-35 system, or the IviePAL jacket and microphone at the same time from the
factory, they were calibrated to each other at the factory. A factory Certificate of Calibration is included with each IviePAL jacket/Microphone
combination. If you purchased a complete IE-35 system including a Dell Axim X51v, the calibration number has been entered into your software
and you DO NOT NEED to complete the calibration procedure below. If you have supplied your own Axim, YOU MUST follow the Initial
Calibration Procedure below.
Periodic Calibration may be performed in the field if you own an SPL Calibrator. The procedure for this is listed below.
Step 1 - With the Axim inserted into the IviePAL jacket, enter into the Calibration mode by selecting the "Calibrate" choice at the bottom of the screen.
Step 2 - Select which microphone you are going to calibrate to the IviePAL jacket. (The LEQ software remembers the calibration values for up to six different microphones)
Step 3 - From the microphone selection window now displayed, tap the Calibrate button
Step 4 - Follow steps 1 - 3 at the bottom of the calibration screen.
Step 7 - Tap the "Done" button.
Step 8 - Tap the "OK" button to accept the calibration.
