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 pre-set to position 5. Try out the product at
this setting and adjust if necessary. Remove the mini-screwdriver
from the base of the Adapter by sliding it out of the bracket.
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, anti-clockwise to decrease. The sound level should be the
same as when you are using the handset. Once you have set
this, the dial only needs adjusting if you change your telephone.
When you have finished making adjustments, replace the
security cover and the screwdriver for future use.
