These instructions
FREEDOM is a four-channel device switcher
that allows a single switch to be routed to one
of up to four devices, allowing a disabled user to
select for him/herself which device the switch
is to be used with at any point in time. Selecting
the device can be achieved either by an extended
press of the switch itself, or by momentarily
pressing a secondary select switch where the
user has the motor capabilities to operate two
switches.
Devices may be of any form, provided they
have a conventional switch input via a 3.5mm
jack socket. Typical configurations might
comprise a communications device, a mobile
telephone and a tablet computer. Some devices
(for example the phone and tablet in the above
example) may require additional equipment to
allow connectivity, such as the APPlicator from

Product Description
Pretorian. All four outputs are fully isolated
so the unit can work with devices which do not
share the same ground potential.
FREEDOM operates from a rechargeable lithium
battery which is charged via the supplied USB
cable, or may be permanently powered from
a power source such as a wheelchair auxiliary
supply. Once the battery is fully charged the
unit will operate for several weeks between
charges without ever needing to manually turn
off the power. This is vital since the user may not
be able to turn off the power.
Both audible and visible low battery indicators
are provided to prompt the user the recharge
and if the battery should become flat, the unit
'fails safe' by routing the switch to device 1
allowing the switch to be used on the most
important device even with no power.
