Operation in C1, C2 or C3 settings:
C1 and C2 use “voice activation” method, this mode of operation supports most phones or brands by
just using the Hold button but with slightly longer activation time (about 10 to 15 seconds after hold is
pressed)
In “Voice activation” mode, the device needs to hear you well therefore speak as close as
possible to the microphone, If you are on a speakerphone or using a headset speak clearly and
louder into the microphone. Be sure to read the NOTES in this section.
To activate: after you receive or make a call, you need to speak and say something before
pressing the button. Audio activates less than 15 seconds later and the corresponding L1
… L4 light on this device will start blinking.
To deactivate hold music just re-select that line and Speak Over the audio, for example say : “Hi I
am Back” , the moment the device hears it will stop the hold-music.
Note: You may also deactivate the hold-music audio by pressing the button.
NOTE1: If you hear a Low Volume audio during your conversation , say something to prevent full
volume hold music activation, this can happen if you or your party are not talking to each other for
about 7 seconds.
NOTE2: If for any reason the hold music is playing, do not panic, simply speak over the audio to stop
it or press FLASH to stop it.
C2: If for some reason you are not able to voice activate or voice -deactivate, Hang up and set the
switch to C2 then try again following the above instructions.
C3: In this switch setting to activate the Hold music press

compatible to hold button activation -see page P3). This mode is useful when you have
