Introduction
The MK:429 is a lightweight Outdoor Microphone unit designed to provide weather protection to
an MV:200 Series Preamplifier and Class+ Microphone Capsule such as the MK:224 and MK:226
units.
This allows Sound Level Meters such as the CR:703B and CR:800A Series to be used for short
term outdoor measurements. Please note that the MK:429 does not provide weather protection
for the Sound Level Meter. Precautions should be taken to ensure that the Sound Level Meter is
not exposed to adverse weather conditions.
The MK:429 is not designed for long term use, and where measurements are required for
extended periods or where the weather conditions are adverse, an alternative system such as
the MK:425 or MK:426A units should be used. For further details please contact Cirrus
Research plc or your local representative.
The MK:429 is compatible with the MV:200B and MV:200C Preamplifiers provided by Cirrus
Research plc and can be used with any of the ZL:2xx Microphone Extension Cables such as the
ZL:205 5m unit.
Please read the enclosed instructions before using the MK:429.

Operation & Use
Calibration
The Sound Level Meter connected to the MK:429 unit should be calibrated as described in the
Operating Manual for the instrument.
Remove the Windshield from the MK:429 to gain access to the preamplifier and microphone
capsule.
Follow the Calibration procedure described in the Operating Manual for the associated Sound
Level Meter.
After calibration, replace the Windshield.
Servicing
The MK:429 unit does not contain any active components and therefore does not require
annual recalibration or servicing.
To maintain the integrity of the seals, a lightweight petroleum based lubricant should be used
on the O-ring seals periodically.
If any of the components are lost or damaged, please contact your local representative or
Cirrus Research plc directly.
The MV:200 Preamplifier used with the MK:429 unit is associated with a Sound Level Meter and
should be kept with the Sound Level Meter at all times.
Do not exchange preamplifiers or microphone capsules with other Cirrus Research Sound Level
Meters or equipment without consulting the Cirrus Research main office.
No responsibility will be accepted by Cirrus Research for damage caused to equipment due to
misuse or the application of incorrect accessories.
