• Insert the tip of a small blade screwdriver, or similar tool, into slot no.

2, shown in diagram on previous page. Gently lever up the retaining

lip of the fuse holder. The fuse holder will then slide out.

• Replace damaged fuse(s) with a suitable replacement – see Section 10

for Power Input Fuse Ratings.

• Replace the fuse holder, ensuring that the retaining lip is properly

home.

At the start of each session the Operator must check the Magstim 200

and the stimulating coil for any signs of damage, paying particular

attention to the plastic casing. If there are any signs of physical damage to

the Magnetic Stimulator, or the stimulating coil, they must not be used.

The coil pins should be checked carefully after every 100 shots for any

signs of pitting, or burning, as under conditions of exceptionally hard use

at high energy levels, it is possible for the localised heating to manifest

itself in the form of micro-welds. Continued used in this condition will

eventually result in the coil pins/sockets becoming totally eroded and

open circuit.

Note: The pin burning is communicable - any coil with good pins that is

used on a stimulator with burned socket pins will have its pins damaged

immediately. The reverse is also true, a socket with good pins that has a

coil with burnt pins connected to it will have its pins damaged

immediately. If damage is noticed on any coil connector or stimulator

coil socket the complete system must not be used until all pins and

sockets are carefully examined for any damage. If any contacts show

damage, even if slight, they will need to be changed. If this is not done

thoroughly there is the risk that the cycle of contact damage will continue.
