HMD 26 / HME 26 / HMDC 26
The HMD 26/HMe 26/HMDC 26 headsets feature
dynamic, closed headphones. The noise-compensating
microphone of the HMD 26 and HMEC 26 ensures
excellent speech transmission even in noisy
environments. The headsets have been designed for
broadcast use, e.g. for outdoor broadcast or broadcast
van applications. The HMDC 26 features NoiseGard™
active noise compensation. The HME 26 is fitted with an
omni-directional condenser microphone and is ideally
suited for studio use.
Features

Switching the microphone transmission off
If, during turning, the microphone boom is in the middle
position (90°), the microphone transmission will be
switched off in order to prevent disturbing noise.
Putting on the headset
When putting on the headset, the patented two-piece
headband adjusts automatically.

Positioning the microphone
Bend the flexible microphone boom so that the micro-
phone is placed at the corner of the mouth. Maintain a
distance of approx. 2 cm between microphone and mouth.
Always use the supplied wind and pop screen.
Flipping away one earcup

Adjusting the volume directly on the audio system
Connect the headset to the corresponding sockets of your
audio system. Adjust the volume directly on the audio
system.
Switching ActiveGard™ on and off (HME/HMD)
ActiveGard™ safeguards your ears from volume peaks
above 105 dB, which can be transmitted via the audio
system or radio equipment. ActiveGard™ is factory-
preset to “on”. You can switch ActiveGard™ off by gently
sliding the switch to the upper position using a pointed
tool.
Hearing damage due to high volumes!
This headset is capable of producing high
sound pressure levels. Higher volumes or
longer durations can damage your hearing!
Set the volume to a medium level. Make sure
that you can hear critical environmental
sounds.
CAUTION!

Powering NoiseGard™ via two (rechargeable) batteries
Insert two 1.5 V AA alkaline batteries (IEC LR 6) or two
1.2 V AA rechargeable batteries (IEC LR 6). Observe correct
polarity when inserting the batteries.
The operating time with batteries/rechargeable batteries
is approx. 100 hours.
With NoiseGard™ switched on (see page 8), the LED 쐇
provides information on the remaining battery/
rechargeable battery capacity.
LED 쐇lights up yellow: The battery capacity is
sufficient.
LED 쐇lights up red: The batteries are flat.
Replace the batteries.

Care and maintenance
Cleaning the headset
Use a soft, slightly damp cloth to clean the headset from
time to time. If the headset is very dirty, use a cloth
dampened with mild, soapy water. Do not use any
solvents or cleansing agents.
Replacing the earpads
For reasons of hygiene, the earpads should be replaced
from time to time. Grasp the edge of the earpad and pull
sharply. Attach the new earpad to the earcup by pressing
firmly around the earpad until you hear all 12 latches lock
into place. Repeat for the other earcup.
Danger of short-circuit due to the ingress of
water!
Water entering the housing of the headset
can cause a short-circuit and damage the
electronics.
CAUTION!
