Do not use the other than AC adapter designed exclusively for the AQ7280.
Battery Pack
Only use the AQ7280 battery pack. Do not use this battery pack with other instruments. Only use the AQ7280 to
charge the battery pack. 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 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 the AQ7280 off, and detach the AC adapter power supply from the AQ7280. 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.
Laser Beam
Do not look directly or indirectly into the laser beam or at a specular reflection of the beam without protective equipment.
Do not aim the laser beam at the eye. The laser beam may cause blindness or damage to your eyes. Attach the cover
to the optical connector when it is not in use. Turn the power OFF when you are cleaning the AQ7280.

Note
Over Discharge and Long Periods of Storage
• If you do not use the AQ7280 for an extended period of time with the battery pack connected to it, the battery pack may become
over discharged. This shortens the service life of the battery pack. To avoid over discharging, if you will not use the AQ7280 for
one week or longer, charge the battery pack, remove it from the AQ7280, and store the battery pack away from direct sunlight in a
location that has an ambient temperature of 10°C to 30°C.
• When you store the battery pack for six months or longer, to replace the power that has been lost through self discharge, recharge
the battery using the AQ7280 once every six months.
• Avoid storing the battery pack for an extended period of time when it is fully charged (after it has just been charged) or when it has
no power left (when the AQ7280 will not turn on). Storing the battery pack under these conditions will degrade its performance and
reduce its longevity. It is better to store the battery pack when it is 40% to 50% charged. This is equivalent to the state the battery is
in after you turn off the AQ7280 and charge an empty battery for an hour at room temperature.
• Use the AQ7280 to charge the battery pack prior to its first use or if it has not been used for an extended period of time.
