The SM1P has level dependent facilities and the criterion levels as
defined in EN352-4 are displayed below:
Model
H

(dBA)
SM1P
108.6
104.6
103.4
TWO-WAY RADIO INPUT (EN352-6)
The electrical input level for which the mean plus one standard
deviation A-weighted diffused-field related sound pressure level is
equal to 82 dB(A) is an RMS voltage U = 108 mV.
SIZE RANGES
Warning- Ear-muffs complying with EN352-1 are of ‘small size
range’, ‘medium size range’ or ‘large size range’. ‘Medium size
range’ ear-muffs will fit the majority of wearers. ‘Small size range’ or
‘large size range’ ear-muffs are designed to fit wearers for whom
‘medium size range’ ear-muffs are not suitable. The SM1P
headband, SM1P behind-the-neck and SM1P helmet adapters may
be adjusted for small, medium or large size.

Noise reduction will be adversely affected by anything that
impairs the seal of the earmuff cushions against the head,
such as thick spectacle frames and balaclavas
The reported attenuation will be obtained only if the headset
is in good condition and worn as directed (Refer to AS/NZS
1269.3 for guidance).
This product should not be used where there is a risk that the
connecting cord could be caught up during use.

Performance may deteriorate with battery usage. The typical
period of continuous use that can be expected from the
headset will depend on the two-way radio battery.
The output of the level-dependent circuit of this hearing
protector may exceed the daily limit sound level. This limit can
be adjusted with a Sensear programming tablet.
