The Tone Frequency and Durations window appears.
2. From the PTT Frequency drop down menu, select the PTT frequency (in Hz).
3. In the Guard Tone Duration field, enter the amount of time (in ms) the guard tone plays before the function tone.
4. In the Guard Tone Magnitude field, enter the level (in dBM) of the guard tone.
5. In the Hold Tone Magnitude field, enter the level (in dBM) of the hold tone summed with TX audio to keep the radio
in a transmit state.
6. In the Hold Tone Hangtime field, enter the amount of time (in ms) the hold tone continues after the release of the
PTT button.
7. In the Function Tone Duration field, enter the duration (in ms) of the function tone.

console is pressed.
NOTE: In the FTone 1-16 Frequency fields, the standard frequencies associated with each function tone are provided
in the first field for the function tone. To change the frequency for a function tone, enter the desired
frequency (in Hz) in the field provided.
10. In the frequency field, enter the desired frequency (in Hz).
11. Enter the desired frequency (in Hz) for the second function tone. An entry of 0 indicates no second function tone is
sent.
12. Click Submit.
