Replacing the Illumination Bulbs
• Before replacing any light bulbs, you must turn off the
power and disconnect the power cord from the AC
outlet.
• Wait until the bulb has cooled to room temperature
before attempting to replace it.
• Never touch a bulb while it is still hot.
• If the bulb burns out, replace it as soon as possible.
• In households with small children, make certain that you
keep all bulbs or screws that you remove well out of the
reach of children, so they don’t accidentally put them
into their mouths.
• Never turn on the power of the illumination while a bulb
is being replaced. If the illumination is powered-on, the
bulb will become hot, and may cause burns.
• You must replace the bulb with a bulb of the specified
model number.
■ Before you continue
• Note which bulb has burned out.
Before you begin, you must note the location of the bulb
that needs to be replaced, to ensure that the illumination
is not powered-on while replacing the bulb.
• Leave the power turned off for at least 20 minutes before
changing the light bulb.
When the illumination is turned on, the light bulb and
the vicinity of the bulb will become hot. Turn off the
power of the instrument 20 minutes before changing the
light bulb, and verify that the vicinity of the bulb is no
longer hot before you exchange the light bulb.
• Obtain the replacement light bulb.
