Service information
To help maintain your Square ONE Splitter unit in good working order and to make sure it gives you optimum
performance, we recommend that you carry out the following procedures. Contact your local distributor if
you require any further service information.
Routine maintenance
About once every month:
• Clean the unit, as detailed in “Cleaning the unit” on page 28.
• Check controls for freedom of operation; this operation may also help to prevent them from sticking.
• Check functionality of all controls, that is, pushbuttons, LEDs etc.
• Check functionality of equipment.
Cleaning the unit
Switch off the unit and electrically isolate it from the mains before cleaning.
Clean the unit using a dry, lint-free cloth. Do not use harsh abrasives or solvents. When cleaning the unit,
take great care not to damage control knobs, pushbuttons etc.
Checking/replacing the mains fuse
The equipment must be independently isolated from the mains voltage supply before any attempt
is made to change or check the protective fuse. The fuse must always be replaced and its drawer
closed before the equipment is reconnected to the mains voltage supply.
Only use the correct replacement type when changing the fuse. Fuse specification is printed on the rear
cover.
To remove the mains fuse, fully open the fuse drawer and prise out the fuse from the mains fuse
compartment (see “Mains supply” on page 13). A small, flat-bladed screwdriver may be useful for this
procedure. Check that the fuse is ok.
Insert new or existing fuse in the mains fuse compartment. If necessary, fit a new spare fuse. Close drawer.
After replacing a fuse, check that the unit is working properly.
