Mounting and Dismounting the Microphone
The microphone can easily be inserted and removed using the locking mechanism lever on the
side of the coupler body.
1. Ensure that the locking mechanism is unlocked.
2. Gently push in the microphone assembly until it touches the end stop and will go no further.
3. Push the locking mechanism lever to its forward position (See Fig. 7).

Calibration
You must remove the microphone/preamplifier when you need to calibrate it. Proceed as follows:
1. Unlock the locking mechanism by pushing it, as shown in Fig. 7.
2. Gently pull out the microphone set.
For proper sensitivity calibration (114 dB at 250 Hz), we recommend the 42AP Intelligent
Pistonphone, but the 42AA Pistonphone can also be used. Refer to the respective manuals for
instructions.
