Speed Control (see Figure 2)

 

This button allows the cursor speed to be changed to suit 

your personal preferences. Press the button briefly to 

change the speed. There are four speed settings to choose 

from. Once you have reached the fastest speed, pressing the 

button again will return the unit to the slowest speed.

Note the speed setting you have chosen is automatically 

retained in your 

n-ABLER

’s memory and recalled after loss 

of power (e.g. if the computer is turned off).

 If the buzzer is enabled it emits a number of beeps to 

indicate the speed whenever the button is pressed. One 

beep indicates the slowest speed and four beeps the 

fastest.

Features

• 

Orientation  Facility

  Your 

n-ABLER

  can 

be  used  in  any  of  the  positions  shown 

in  Figure  3.  This,  together  with  the 

option  to  mount  your 

n-ABLER

  on  a 

bracket,  allows  it  to  be  mounted  in  many 

different  ways  to  make  using  it  easier. 

The  default  setting  is  with  the  computer 

lead  furthest  from  you.  If  you  prefer  this 

you do not need to do anything. If you prefer 

to use it in a different position follow the 

steps in the Learn Mode section.

• 

Buzzer

  The  buzzer  gives  an  audible 

indication  as  you  select  or  deselect  some 

of  the  features.  The  default  setting  for 

the  buzzer  is  ‘on’  and  you  don’t  need  to 

do  anything  if  this  is  your  preference.

If,  however,  you  like  to  work  in  a  quiet 

environment  and  wish  to  have  the  buzzer 

‘off’  follow  the  steps  in  the  Learn  Mode 

section.

• 

Left/Right  Button  Swap

  If  you  are  left-

handed, or wish to use your 

n-ABLER

 ‘upside 

down’ you may wish to swap the Left and Right 

buttons around. If so follow the steps in the 

Learn Mode section.

• 

External  Switches

  Two  sockets  are 

provided  at  the  rear  of  the  unit  to  allow 

external  switches  to  be  connected.  By 

default,  the  socket  adjacent  to  the  Red 

Button performs the same function as the 

Red Button, and the socket adjacent to the 

Yellow Button performs the same function 

as  the  Yellow  Button.  Suitable  switches 

are  widely  available  from  retailers.  

Note  that  the  external  switches  work  in 

addition to the internal ones. 

  Warning:  These  jack  sockets  are  not  for 

external  power  supplies.    Never  connect 

an  external  power  supply  to  the  unit, 

otherwise permanent damage may occur.

• 

Dwell  Click

  Some  users  may  experience 

difficulty in using both the n-ABLER buttons 

and  external  switches.  As  an  alternative, 

the  Dwell  Click  feature  may  be  enabled  to 

automatically perform a button click a short 

time  after  the  cursor  has  stopped  moving. 

For  example,  if  the  Double  Click  button  is 

selected,  an  application  may  be  started 

simply  by  moving  the  cursor  over  its  icon 

and waiting for the selected dwell period.
