NOTES
1. All transmit measurements are made with 94 dB SPL drive at 1000 Hz into a
10K ohm resistive load with the voice tube fully retracted. All values are
nominal.
2. All receive measurements are made with -38 dBV drive at 1000 Hz with foam
cushions using an IEC supraural coupler per ANSI S3.7 and with the volume
control switch in Position I.
3. Voice switch point is the sound pressure level at which the amplifier sensitivity
increases due to detection of spoken sounds.
4. Switch depth is the decrease in amplifier sensitivity when sound pressure
input drops below switch point.
5. Switch-up time is the delay in amplifier sensitivity increase after sound
pressure exceeds the switch point.
6. Switch-down time is the delay in amplifier sensitivity reductions after the
sound pressure falls below the switch point.
