Amount is regarded as people more than thresholding and is speaking so that judging whether is more than internal thresholding, and then opens transmitting；Keystroke pattern
It is that PTT is emitted or received by key control, is considered within long-pressing PTT key 1 second or more that request emits, hence into emission state,
It unclamps PTT key 0.5 second and enters reception state.
Step 5: setting channel:
End host carries out voice broadcast using the voice menu prestored in speech chip, by earphone, prompts setting institute
The communication channel of portable underwater telephone terminal is stated, and according to the state of PTT key in waterproof mask, determines that user selectes logical
Believe channel.
Step 6: setting volume: the volume that earphone is listened in setting mask.
End host carries out voice broadcast using the voice menu prestored in speech chip, by earphone, prompts setting institute
It states the volume that earphone in waterproof mask is listened to, and determines that user selected listens to volume according to PTT button state.Volume is divided into two
Shelves "high" and " low " are realized by the signal amplification factor inside setting program.
Step 7: setting noise suppressed:
End host carries out voice broadcast using the voice menu prestored in speech chip, by earphone, prompts described anti-
Noise elimination function whether is opened in face guard, and the selection of user is determined according to PTT button state.
It is that the noise elimination function of earphone is arranged that noise suppressed, which is arranged, sets " noise suppression for submarine terminal by voice menu
System is opened ", when there was only other side's transmitting in this way, it can just hear that other side talks, earphone is in mute state when other side does not emit, and in this way may be used
To reduce power consumption to a certain degree；When being set as " noise suppressed pass ", other side can hear that other side speaks when emitting, and other side does not emit
When can hear received noise, such benefit is, on the user for being unfamiliar with equipment may determine that whether machine normal
Electricity and normal work.
