Personal Safety Warnings
These servicing instructions are for use by qualified personnel only.
To avoid electrical shock, do not perform any servicing unless you
are qualified to do so.
The opening of covers or removal of parts is likely to expose
dangerous voltages. Disconnect the instrument from all voltage
sources while it is being opened.
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.
The power cord is connected to internal capacitors that may remain
live for 10 seconds after disconnecting the plug from its power
supply assembly. Wait at least 10 seconds, after disconnecting the
plug, before removing the covers.
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).
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.
