WARNING The opening of covers or removal of parts may expose dangerous voltages. Disconnect the
instrument from all voltage sources while it is opened.
WARNING 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.
WARNING Procedures described in this document may be performed with power supplied to the
product while protective covers are removed. Energy available at many points may, if
contacted, result in personal injury.
WARNING The power cord is connected to internal capacitors that may remain live for 10 seconds
after disconnecting the plug from its power supply.
WARNING For continued protection against fire hazard, replace line fuse only with same type and
rating. The use of other fuses or material is prohibited.

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).
