Failure to comply with the precautions below could lead to injury
or death or damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
This instrument is a waveform measuring device that monitors and measures electrical
signals. Do not use this instrument for anything other than as a waveform measuring device.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Battery Pack
Only use the battery pack for this instrument. Do not use this battery pack with other
instruments. Only use this instrument to charge the battery pack.
When the battery pack is charged with the instrument turned off, if the battery pack is still
charging after 6 hours, stop charging it immediately.
Your clothing may be damaged or you may be injured if you come in contact with the
electrolyte in the battery pack due to fluid leakage or the battery pack exploding. Because the
electrolyte may cause loss of eyesight, if it comes in contact with your eyes, immediately wash
the affected area with clean water, and consult a doctor as soon as possible.
When you change the battery pack, be sure to turn off the device under measurement, and
disconnect it. Failure to do so may lead to electric shock or other accidents. Do not throw the
battery pack into fire or heat it. Such actions are dangerous as they may cause the battery
pack to explode or the electrolyte to be sprayed about.
Follow the additional handling precautions that are included in the battery pack's user's
manual.
