Alert Tone Select
The various alert tones that sound are described in Section 2.5. These tones can be turned
ON and OFF if the Alert Tone option button or Tones menu parameter is programmed.
When all tones are OFF “Tone Off” is momentarily displayed, and when all tones are on,
“Tone On” is momentarily displayed. If this button or menu parameter is not programmed,
tones are fixed in the on or off mode by programming. If the Surveillance mode is
programmed (see following), tones are totally disabled.

The Alert Tone volume can be adjusted relative to the volume control setting. This is done
by programming and also by the user if the Tone Volume Adjust option button or menu
parameter is programmed. Relative levels of –170 to +170 can be set with “0” the default
setting. The range is divided into the number of volume ticks set in “Volume Ticks”. For
example, if “Volume Ticks” is 10, the tone adjustment on the radio will go from -5 to 5. A
minus value decreases the tone volume and a plus value increases it. The user adjusted
level permanently overrides the programmed level if applicable.
