Call Signal Tone (in Earphone), Function 6
When this function is on, the beltpack produces an audible call signal
in the headset when a call signal is received.When this function is off,
it does not.
The audible call signal’s volume level is preset. (Volume may vary
slightly, depending on headset.) This function is useful for unspoken
cues when a visual call signal is not practical or effective.
To select an “audible call signal”:
1. Press and hold the setup button until the setup information
window displays a “P” and then release the button.
2. Repeatedly press the call button until “6” appears in the display.
3. Press the talk button to toggle “audible call signal” to either on or
off.
The talk light reveals whether “audible call signal” is on or off. If
the talk light is on, “audible call signal” is on; if the talk light is off,
“audible call signal” is off.
4. When you have made your selection, press the setup button to save
it and to exit setup, or press the call button to select other
functions to program.
If you do not press a button within five seconds, the beltpack exits the
setup program without making any changes.
