CONNECTION & SETUP
GB
INSTALLING THE BATTERIES
Refer to Figure 2 Battery compartment
As an alternative to the AC adapter, the VistaPlus can be operated
from two alkaline AA batteries. To install the batteries, remove the
battery cover on the bottom of the adapter. Install the batteries into the
compartment the correct way round as shown on the inside of the
battery cover and then replace the cover.
The LED indicator on the top of the VistaPlus will flash every two
seconds when the batteries need replacing.
Disconnect the AC adapter from the VistaPlus and unplug it from the
mains supply when using batteries.
ADJUSTING THE ADAPTER
Refer to Figure 3 Switches on the bottom of the unit
The compatibility switch on the bottom of the adapter allows VistaPlus
to operate with most business telephones. This switch is set to position
A, but if you cannot hear a dial tone move the switch to one of the
other positions (A-F). Once you have found the setting that works, it
will not need to be changed unless you change your telephone.
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.
