4. OTHER FUNCTIONS
• The last settings are stored when t
he headset is switched off.
• Automatic power-off after two hours of no active functions. Automatic
power-off is indicated by a voice message:
“automatic power off”.
• Low battery level is indicated by a voice message:
“low battery”.
5. IMPORTANT USER INFORMATION
The hearing protector must be worn, adjusted, cleaned and maintained in
accordance with this manual.
• The hearing protector features active volume. Check that this feature works
before using the unit. If distortion or flaws are discovered, consult the
manufacturer’s instructions for maintenance and battery replacement.
• Always wear the hearing protector at all times during exposure to
hazardous noise
• Certain chemical substances may damage this product. Contact the
manufacturer for more information.
• The hearing protector is fitted with an electric audio input. Check that this
feature works before using the unit. If distortion or flaws are discovered,
consult the manufacturer’s instructions.
• If sound distortion increases or the volume becomes too weak, it is time to
charge or replace the batteries. Never replace or insert batteries with the
unit switched on. Ensure that the batteries are correctly aligned before
using the product.
• Store product without the batteries.
• Under extremely cold conditions, warm the hearing protector before using.
•
The wearer should ensure that the ear-muffs are regularly inspected for
serviceability.
• The fitting of hygiene covers to the cushions may affect the acoustic
performance of the ear-muffs
Note:
If these recommendations are not followed, attenuation may be
adversely affected leading to hearing impairment.
WARNING!
The sound from the active-volume circuit on the hearing protector may exceed
the external sound level.
IMPORTANT! For the best protection, brush aside hair around the ears so the
ear cushions fit snugly against the head. Spectacle frames should be as thin as
possible and fit close to the head to minimise acoustic leakage.
Operating temperature: -20 °C to +55 °
6. TECHNICAL DATA
6:1 Attenuation values, SNR (D)
The attenuation values and noise levels for the headset are tested and
approved according to EN 352-4: 2001, EN 352-6 : 2002, EN 352-8 2002 and
applicable parts of EN 352-1 2002. Certificate issued by FIOH (registration
no. 0403).
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Average attenuation (dB)
4. Standard deviation (dB)
5. Expected attenuation (dB)
6:2 Input signal level/usage time for audio input J22 (E)
Maximum permitted audio signal in relation to usage time.
To prevent harmful effects on hearing, the input signal should not exceed the
specified values (average speech sound level). The long-term average value
of the earphone volume is measured at a level corresponding to no more than
82 dB(A) sound level.
1. Hours/day
2. Average level/electric signal X = 20 mV
