INSTRUCTIONS GB
The Adapter has a low battery indicator which gives 3 beeps when you begin a call. If you hear this then replace the batteries as soon as possible.
SETTING THE 6 POSITION SWITCH
The Vista is supplied
Use the screwdriver to set the switch to the correct position for your telephone.
FITTING AND REMOVING THE SWITCH COVER
On the left of the Adapter is a cover. To remove it, hold the Adapter firmly and put your thumbs on the cover grips. Press and slide the cover downwards. This gives you access to the adjustments for the transmit level and the 6 position switch.
ADJUSTING THE TRANSMIT LEVEL
The transmit level is how loud or quiet your voice is heard by people on the other end of the line.
The Adapter can be adjusted to set the optimum transmit level. However, you need to fully install your headset before you make this adjustment.
When you have completed your headset installation, put on your headset and make a call to a colleague. Use the screwdriver to adjust the dial until the ideal sound and tone levels are reached. Turn the dial clockwise to increase the sound level,
When you have finished making adjustments, replace the security cover and the screwdriver for future use.
