OPERATING FEATURES / REALIGNMENT

7. Audible user feedback tones

The transceiver outputs various combinations of tones to notify the user of the transceiver operating state. The main tones are listed below

The high tone is 1477Hz, the mid tone is 941Hz, and the low tone is 770Hz.

• Power on tone

This tone is output when the transceiver is turned on. (The high tone is output for 500ms.)

• Alert tone

This tone is output when the transceiver is in TX inhibition for TOT, battery warning and PLL unlocked. It is output until the PTT button is released. (The 697Hz tone is output.)

• Busy Tone

This informs the user of a busy channel lock out

• Group Call Tone

The group call tone informs the user of a group call in DTMF/ 2 Tone Option Signaling. This tone repeats 7 times.
