4.3.6 Audio probe function
On the control box, the audio probe connector is the same as that for the wire seismic sensor.
This means that either the audio probe, or the wired seismic sensor, can be connected.
By default, listening to the victim has priority
(see figure 1).
Transmission from the rescuer to the victim
is established by keeping the Push-to-talk key pressed down.
Transmission to the victim does not allow the victim to be listened to while the Push-to-talk button
is being pressed
(see figure 2).
A second headset can be connected. The second headset has
the same functions as the first. If the Push-to-Talk button is not pressed, both headsets communicate
with each other without the victim being able to hear.
By default the headset sound and speaker volume are pre-set to 50%. To change the volume,
select the headset or the speaker using the "▲" and "▼" keys then validate using the validation key.
To exit the "audio sensor" function, use keys "▲" and "▼" to select the icon showing the wireless
seismic sensors and validate
