Safety Precautions
To use the instrument safely and effectively, be sure to observe the
precautions given in the user’s manual. Not complying might
result in injury or death.
Warning
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the AC adapter and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord
Use only the power cord that comes with the instrument. Do not use it for other
devices.
Use the Correct AC Adapter
Use only the AC adapter specified for the instrument. Do not use it for other
devices.
Use Only the Designated Battery pack
Use only the battery pack specified for the instrument. Do not use it for other
devices.
Use only this instrument or a charger specified by Gradway to charge the
battery pack. If the fast charge does not finish after three hours or more, stop
charging the battery pack immediately.
To prevent the possibility of electric shock and accidents, always turn OFF the
power switch and remove the AC adapter power supply from the instrument
when replacing the battery pack.
Do not throw the battery pack into fire or apply heat to it. This can cause
dangerous explosions or spraying of the electrolytes.
Do Not Look at the Laser Light
Do not look at the laser’s direct ray, reflected ray from a mirror, or indirect ray
without the proper protective eyewear. In addition, avoid being exposed to the
laser light. It can cause blindness or damage to the eye.
Do Not Operate in an Explosive Atmosphere
Do not use the thermocouple in a location where any flammable or explosive
gas/vapor is present. Operation in such an environment constitutes a safety
hazard.
Do Not Remove Covers
The covers should be removed by AD INSTRUMENTS’s qualified personnel

6
only.
Opening the cover is dangerous, because some areas inside the instrument
have high voltages.
Carrying and Moving the Instrument
Remove all power cords and connection cables from the main unit before
moving the instrument. When carrying the instrument, hold it firmly by the
handle.Also, if storage media is inserted into the instrument, always remove
the storage media before carrying or moving the instrument. Never leave the
media inserted when carrying or moving. The storage media can become
damaged.
Apply Correct Signals to the Optical Connectors
Do not apply light that is —10dBm or greater to the FHO 5000 optical
Connectors.
Doing so may damage the AD5000
