Pressure Zone Microphone  (330-1090A)   Preparation    Faxback Doc. # 14682

BATTERY INSTALLATION

Remove the battery compartment cover of the in-line power supply by
pressing it in the direction of the arrow.  Install one AA alkaline
battery, such as our 23-552; observe polarity (+ and-) as indicated in the
compartment.

Note:  For greater dynamic range and higher sound pressure level, you can
       use two 23-469 batteries.  If you use these higher voltage
       batteries, you must remove them when not using the mic.

Caution:  When the PZM is not in use, leave the ON/STAND BY/OFF switch set
          to OFF.  If you will not use the PZM for a week or more, remove
          the battery.  Never leave a weak or dead battery in the battery
          compartment.  Even "leak proof" batteries can leak damaging
          chemicals.

CONNECTION AND SWITCH SETTINGS

You may connect the PZM to the low impedance jack on any tape deck, PA
system or mixer that has 1/4" (6.35 mm) plugs.  Position the in-line power
supply so that it will not be tripped over and damaged.  Use the in-line
power supply switch as follows:

OFF:         To turn the PZM off completely
STAND BY:    To turn off the PZM temporarily during use.  If you use the OFF
             position for this purpose, there will be a "pop" when you turn
             the PZM on again.
ON:          To turn the PZM ON for normal use.

Note:  When using the PZM outdoors, the windscreen will reduce wind noise.
