4.3 Menu: Description of the Seismic mode functions
4.3.1 Seismic mode
The seismic menu appears when one or more seismic sensors are connected. The bar-charts are shown
for each connected sensor, with the maximum level carried over. By default the sensor sound gain is set
to 50%. The browser "▲" keys increase the gain for all sensors and the "▼" keys reduce it.
A headset icon placed under each bar graph indicates that the sensor is audible. It is MONO:
the sound can be heard in both ears.
The option to listen or not listen to a sensor is made using the keyboard keys located below each bar
chart. In the configuration below each sensor can be heard in both earphones on the headset.
There is a second listening mode
on the seismic menu: STEREO mode.
It is used to concentrate listening
to the sensors using the left or right ear.
This second mode can be accessed by
pressing the
"Toggle"
key. Once this
mode has been selected, the user can
listen to each sensor in the left or right
headset earpiece using the keyboard
keys located beneath each sensor
(or all the sensors at the same time).
This listening direction is shown by
an arrow pointing left when listening
in the left earpiece, and pointing right
for the right earpiece.
The tracer turns red on the sensor that detects the highest peak. If 2 sensors
detect the highest peak at the same time, then they will both be red. This tracer
is carried over onto the scale for easier readings.
