8 Operation
8.1 Start/Stop talking
The console device has a “PTT” (push to talk) button. Push this button to talk to the other station. You can either
talk permanently or temporarily. Push the button briefly and release it (< 250 ms) to activate the permanent
mode. You do not need to hold or operate any controls while talking in this mode. Push briefly (< 250 ms) to
deactivate the mode again. If you push and hold the button (> 250 ms), you activate the temporary mode. In this
mode, you can talk as long as you hold down the button. Releasing it deactivates the temporary mode instantly.
The mobile device has a “Mic” switch button. Switch or push this button to talk to the other station. You can either
talk permanently or temporarily. Switch the button to "On" to talk permanently. The button stays in this position
and allows you to talk to the other station until you switch the button back to "Off“. Push the button to "(On)" to
talk temporarily. You can talk as long as you hold the button in this position. The button switches automatically
back to "Off” when you release it.
Only one station can talk at a time. A blinking power LED indicates that talking is active.
Example:
The “Mic” button of the mobile device is set to permanently on. If the console “PTT” button is pushed, the mobile
device is not allowed to talk anymore, until either the console deactivates talking or the mobile device switches
the “Mic” button “Off” and “On” again.
8.2 Volume Control
The mic/line in input gains are controlled by software and can be adjusted by turning the “Volume In” knob. After
20s of inactivity, the values are permanently stored. By pushing and holding (> 2s) the “Volume In” button, the
gains can be reset to default which is indicated by a one time blinking of the “Info” LED.
The speaker output volume is controlled by hardware and can be adjusted by turning the “Volume Out” knob.
§
Speaker Damage when volume is too high
A too high speaker volume can lead to extreme loudness or an overload of the speaker. When
taking the devices into operation, turn off the speaker volume in order to avoid any damages.
