User Service
To prevent electric shock do not remove the instrument cover. There are no user
serviceable parts inside. Routine maintenance or cleaning of internal parts is not
necessary. Any external cleaning should be done with a clean dry or slightly
damp cloth. Avoid the use of cleaning agents or chemicals to prevent any foreign
liquid from entering the cabinet through ventilation holes or damaging controls
and switches, also some chemicals may damage plastic parts or lettering. Any
replacement cables and high voltage components should be acquired directly
from APT or its distributors.

The instrument must be returned at least once a year to an APT authorized
service center for calibration and inspection of safety related components. APT
will not be held liable for injuries suffered if the instrument is not properly
maintained and safety checked annually.

Unauthorized user modifications will void your warranty. APT will not be
responsible for any injuries sustained due to unauthorized equipment
modifications or use of parts not specified by APT. Instruments returned to APT
with unsafe modifications will be returned to their original operating condition at
the customer’s expense.
