Routine maintenance
To help keep your Square ONE Dynamics unit in good working order and to make sure it gives you optimum
performance, we recommend that you carry out the following about once every month:
• Clean the unit, as detailed in “Cleaning the unit” on page 42.
• Check controls for freedom of operation. As the controls are ‘self-cleaning’, this operation will 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 and its cover must always be replaced
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 fuse, pull out the fuse drawer (see “Mains supply” on page 15). Then, prise out the fuse from
the furthest compartment (the nearest compartment is for a spare fuse); a small, flat-bladed screwdriver
may be useful for this.
Insert new or existing fuse in the furthest fuse compartment and close drawer.
After replacing a fuse, check that the unit is working properly.
