The grid on the left of the page shows all configured Alert Tone generators. Alert Tone generators may be
selected by clicking on them. Multiple generators may be selected by clicking on each one while holding
down the SHIFT key. Alert Tone generators that are selected will have a blue background.
The following settings may be changed for each Alert Tone Generator:
Tone Frequency: Sets the frequency of the tone to be played when the alert is triggered. There is special
operation for the High/Low tone style. See below.
Tone Style: The tone is played in one of the following four styles:
Continuous
– Continuous beep.
On/Off
– Repeating ½ second beeps with a ½ second gap between each beep.
Intermittent
– A group of 3 ½ second beeps, with a 2½ second gap before repeating.
High/Low
– Tone alternates between the selected frequency and a tone of ½ the selected
frequency. For 1000Hz. and 800Hz. the low tone is 600Hz. and for 600Hz. the tone is continuous.
Alert Priority: If an alert of lower priority is currently playing, then triggering a higher-priority alert will
silence the lower-priority alert, until the higher-priority alert is cleared. Alerts of the same priority will play
simultaneously.
TONE VOL: Sets the output volume on the selected alert in dB, with 0dB being the maximum volume.
Mute on PTT: If this is set, transmitting on any radio will mute the alert tone for the crew member who is
transmitting.
When a setting is changed, the web page updates the hardware with the new setting. While this is
happening, the webpage will prevent further changes (Figure 7).
