Setting the speak volume

The speak volume is how loud or quiet your voice is heard by someone on the other end of the line. Put on your headset and tell a colleague you are making a test call to them. If they cannot hear you, move the ‘speak volume’ slider on the bottom of the adapter until they can hear you.

You may also need to decrease the speak volume if this is set too high. Position 9 on this slider is the loudest; position 1 the quietest. When you have set the speak volume, you should not need to change it, unless you change telephones.

Setting the receive volume

VistaPlus has a volume control which you can use to adjust the volume of your caller’s voice. Step the volume up and down by pushing the volume switch on the top of the adapter until it is set at a comfortable level. The adapter will maintain this volume regardless of the volume of the incoming call and so you should not need to adjust the receive volume very often. Receive volume can be adjusted while you are in a call, if required.

SoundGuard Digital protection ensures that the volumes do not exceed legally defined levels over the course of a working day and will protect you from sudden high volume noises which may occur.

Adjusting the tone control

The tone control lets you improve the clarity of calls. There are three settings; push the tone control button while you are making your test call and select the preferred setting.

Headset / handset mode

VistaPlus can be operated in two modes: headset or handset. To use headset mode, press the headset button on the top of the adapter so that you can see the green square. Press this button again to switch to handset mode. In handset mode, the telephone can be used normally.

Using the mute switch

VistaPlus has a mute button so that you can still hear the caller, but they cannot hear you. To use the mute function, press the mute button

so that you can see the red square indicator. Press the button again when you want your caller to hear you. Note that mute only works with headset, not with handset.

Leaving your desk while making or taking a call

If you need to leave your desk during a call, you can keep your headset on and simply disconnect the QD connectors. On some systems, this may hang up the call or place it on hold.

Warnings

The LED indicator on the top of the adapter indicates when SoundGuard Digital protection is active. The light will go out when the noise goes away.
