Brother PJ-722 Product Safety Manual page 5

 A liquid (electrolyte) leaking from the printer or rechargeable battery may indicate that the
rechargeable battery is damaged. If the rechargeable battery leaks, immediately stop using the
printer, unplug the AC adapter, and isolate the printer by placing it in a bag.
DO NOT touch the electrolyte. If the electrolyte gets in the eyes, do not rub them. Immediately
rinse the eyes liberally with tap water or other clean water and seek the advice of a medical
professional. If left unattended, the electrolyte could cause eye damage. If the electrolyte comes
into contact with your skin or clothing, immediately rinse them with water.
 DO NOT put the rechargeable battery, or a printer with the rechargeable battery installed, into
a microwave oven or high-pressure container.
 DO NOT disassemble, modify, or attempt to repair the rechargeable battery.
 DO NOT dispose of the rechargeable battery in fire or intentionally overheat. This could cause
the internal insulation to melt, gas to be emitted, or safety mechanisms to fail. Additionally, the
electrolyte solution could catch fire.
 DO NOT puncture the rechargeable battery with any objects, subject it to severe shocks or
throw it. Damage to the rechargeable battery's protection circuit could cause the rechargeable
battery to be recharged at an abnormal current/voltage or cause an abnormal chemical reaction
within the rechargeable battery.
 DO NOT leave a drained rechargeable battery in the printer for a long period of time. This could
shorten the life of the rechargeable battery or lead to an electrical short.
 DO NOT incinerate the rechargeable battery or dispose of it with household waste.
If the printer can only be used for a short period of time, even though the rechargeable battery is
fully charged, the rechargeable battery may have reached the end of its service life. Replace the
rechargeable battery with a new one. When removing and replacing the rechargeable battery, cover
the terminals of the old rechargeable battery with tape to avoid creating a short in the battery.

DO NOT use the printer in special environments, such as near medical equipment. Electromagnetic

Car adapter from the electrical socket, and then contact your Brother dealer. If you continue to
operate the printer, a fire, electric shock, or damage may occur.
