electrical shock, do not perform any servicing unless you are qualified to do so.
Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended. Discard used batteries
according to manufacturer’s instructions.
For continued protection against fire hazard replace line fuse only with
same type and rating. The use of other fuses or material is prohibited.

dangerous voltages. Disconnect the instrument from all voltage sources
before opening.

The detachable power cord is the instrument disconnecting device. It
disconnects the mains circuits from the mains supply before other parts of the
instrument. The front panel switch is only a standby switch and is not a LINE
switch (disconnecting device).
Connector Care and Cleaning Precautions
Remove the power cord to the instrument. To clean the connectors use alcohol in a well
ventilated area. Allow all residual alcohol moisture to evaporate, and fumes to dissipate prior to
energizing the instrument.
