6.2 Hardware Repairs
A consequence of modern surface-mount construction is that it is frequently no longer possible
for local repairs to be made. Special and expensive equipment is required to change parts. As
well, today’s equipment is complicated and requires repair technicians to have specic product
experience and training and access to high-end test equipment.
At the same time, the advent of overnight delivery services means that equipment can be
returned to the factory for quick turn-around repair. erefore, we do not expect you to repair
this unit at the component level, and we do not include schematics of the unit in the manual.
Upon request, our support sta can fax or mail you a schematic, should you need one. Please see
the rst pages of this manual for proper procedures on returning units for repair.
