1. Introduction
The WS-15 wind screen is designed for outdoor installation. It helps to reduce wind noise and is equipped
with rainproof features that satisfy the IPX3 water-resistant specifications. It is used with a microphone
extension cable, which means that the microphone/preamplifier has to be separated from the sound level
meter, before the wind screen can be mounted.
This manual will describe the mounting procedure (paragraph 3), the settings on the sound level meter
(paragraph 4) and technical specifications of the wind screen (paragraph 5).

3. Mounting the windscreen
To mount the windscreen WS-15 onto the microphone/preamplifier combination of a RION sound level meter
(when the microphone/preamplifier combination is separated from the sound level meter), please perform the
steps below. The tripod, extension cable EC-04 series, and mounting adapter for windscreen are all available
as options. Before using equipment such as the sound level meters and preamplifiers, carefully read the
instruction manual for each device. The preamplifier models that can be mounted on the WS-15 are as
follows: NH-21, NH-23, NH-24, NH-25, and NH-26.
1. Turn off the sound level meter.
Then loosen the preamplifier
fastening screw and remove the
microphone/preamplifier
combination from the main unit.
Please refer to the picture on the
right.
IMPORTANT:
Do not try to remove the microphone
from the preamplifier. This may lead
to damage to the microphone or
preamplifier. Also, never remove the
microphone grid, because this can
lead to damage.
2. Attach the mounting stage for microphone to the
tripod.

4. Connect the extension cable EC-04 series to the
preamplifier. Make sure the fastening screw is turned on
hand-tight to ensure a good connection.
IMPORTANT:
When using WS-15, remove the windscreen slip-off
prevention rubber:

5. Attach the mounting adapter for windscreen. The
mounting adapter for windscreen has a slit along the
side. To attach the adapter, slide the cable section of the
extension cable EC-04 series through the opening. For
this step, it is important to note that the direction in
which you insert the mounting adapter for the
windscreen differs according to the preamplifier
model you are using (type number can be found on
preamplifier housing, or on the name plate of the sound
level meter). Please see below:

Edition 2013-09
6. Insert the preamplifier into the mounting stage for
microphone from the top.
7. Insert the preamplifier into the base of the WS-15 and
rotate the base to securely fasten it to the mounting tube.
Then insert the inner cap through the wires of the base
and cover the preamplifier with the inner cap firmly.
While doing this, take care that the tips of the spring tips
attached to the base do not come into contact with the
microphone.
IMPORTANT:
Be aware that if you put the windscreen and the base
together beforehand, the inner cap may be displaced and
the preamplifier may not fit into the inner cap.
IMPORTANT:
Handle the base with care, to prevent the risk of injury
by the sharp spring tips.

Edition 2013-09
8. Mount the windscreen. In the lower part of the
windscreen, there are three slits. Align these slits with
the hooks on the base and push the windscreen fully
onto the base.
See also the picture below for slit alignment:
9.Push each of the three tips of the springs attached to
the hooks firmly into the windscreen, at about the
middle section. When pushing the tips into the
windscreen, make sure the tips are perpendicular to
windscreen surface.
IMPORTANT:
Handle the spring tips with care, to prevent the risk of
injury by the pointed spring tips.
