This is a passive transformer isolated device. It has no connection to AC power and has
no hazardous internal voltage.
However, it does contain very sensitive internal circuitry. The lid provides essential
shielding for sensitive components and should not be removed during use or any other
time.
The MSX48 has no user serviceable parts inside and should be returned to the manu-
facturer should servicing become necessary. Your warranty does not cover any damage
caused by modifications or service work performed by non authorised personnel. Refer
to the International Limited Warranty on Page 8 for more details
