Basic Operations
Headset will give a “battery low” warning
every one minute when battery voltage
is low. Additional warnings will occur as
hearing protector powers down. Replace
batteries at this time.
After 2 hours of non-activity, a 10-second
countdown will begin before hearing protector
automatically powers down. To reset auto shut-
off, simply adjust volume knob.
After auto shut-off, turn On/Off/Volume knob to
“off” position for 2 seconds, then back to “on.”
The safe volume control technology allows for
increased music volume while protecting your hearing,
by controling sound levels over an 8-hour work day.
Higher sound exposure is allowed for a period of time,
and then gradually reduced if necessary below the long
term average of 82 dB(A) for extended use.
