Press the LD button (A15) to switch the level-dependant function ON. A voice message conrms the
function and a symbol will show on the display home screen. The volume is adjustable in 5 levels(1,
2, 3, 4, MAX). Adjust the volume by pressing the LD button until you reach your desired volume level. The level will be indicated
with a voice message and on the display. Press and hold the LD button to switch the Level-dependent function OFF. The
headset remembers your last volume setting the next time you switch ON the headset or the level-dependant function.
For use in windy environments it is recommended to t the two included windshields (B:6). Remove the peel o󰀨 lm and t the
windshield perfectly centered over the Level Dependant microphones (A7).
This hearing protector is provided with level-dependent attenuation. The wearer should check correct operation before use. If
distortion or failure is detected, the wearer should refer to the manufacturers advice for maintenance and charging of the battery.
Warning! The output of the level-dependent circuit of this hearing protector may exceed the external sound level.
Radio Volume
The volume of the incoming radio can be congured with the up and down buttons (A13 >) (A12 <). The volume is adjustable
in 5 levels (OFF, 1, 2, 3, 4, MAX). The Radio can be turned OFF by turning the volume down, press and hold the down button
when on volume level 1. A radio o󰀨 notication will be heard with 10 minute intervals. To turn the radio ON increase the radio
volume.
PTT (Push To Talk)
Press and hold the PTT button (A16) to transmit on the selected radio channel. Release the button to stop transmitting.
Radio channel (frequency)
Se table E:12 for available channels and frequencies. When two (or more) radios are congured on the same channel, they can
communicate with each other.
Sub channel (selective squelch)
Using sub channels enables multiple groups to use the same radio channel without disturbing each other. When activated,
transmissions are coded with the sub channel and only received messages on the same sub channel will be heard. A unit with
sub channel turned OFF will hear transmissions from all sub channel groups. Sub channel grouping is achieved with sending
units overlaying a tone to the transmitted audio which receiving units can detect and open the selective squelch. See table E:13
for available sub channels and their tone frequencies.
VOX (Voice Operated Transmission)
When the VOX is activated, radio transmission is automatically started when the speech signal from the microphone is above a
certain level (threshold). Double press the PTT button or use the menu to enable/disable the VOX and set the desired threshold
(OFF, 1, 2, 3, 4, MAX). A lower threshold allows a weaker speech signal to activate transmission. A higher threshold might be
needed when the background noise is higher to prevent false triggering of transmission. When enabled, a VOX symbol is shown
on the display home screen. Also when VOX is enabled the PTT button can be used to manually control transmission.
Note, for reliable VOX triggering and clear communication the microphone needs to be correctly rotated and approximately 1
cm from your mouth.

button as well as the VOX functionality. Two descending tones are given as feedback when transmission is prevented. TX allow
can be congured in the following settings:
Always: transmission is always allowed
Channel free: transmission is allowed if the channel is free
TX power
Sets the power at which the headset transmits the radio signal (LO, MED, HI). Higher power can extend the range or improve
reception for others in challenging environments. Lower power uses less battery when transmitting and extends operating time.

8
TX power is automatically reduced from HI to LO if battery status is running low. HI TX power is not recommended when using
Alkaline batteries due to reduced operating time.
Voice
Selects if voice prompts are activated (ON,OFF).
Version
Displays product serial number and product revision.
Squelch (radio noise suppression)
Noise from the radio reception is blocked when the incoming signal is below the set squelch threshold (1, 2, 3, 4, MAX). A lower
setting can increase the radio range but might open up for more noise.
Reset
Resets device to factory default settings.
Battery save function
The headset has built in battery save function that turns the headset o󰀨 when not used. When no movement has been detected
for 10 minutes the headset tuns o󰀨, otherwise it turns of after 2 hours of inactivity.
Low battery warning
When the battery power is decreasing and approximately 10% of operation remains, a voice prompt “battery low” will be heard
in the headset. The batteries should then be charged as soon as possible. The headset will turn OFF when the batteries are
drained.
Replacement of batteries
Unscrew the thumbscrew (A18) that secures the battery pack (A17). Remove the battery pack
from the earcup. Replace batteries, take note of battery orientation. The headset can run on both
rechargeable (HR6 NiMh) or disposable batteries of AA type 1.5V. Alkaline batteries only for short
