DANGER
Rechargeable Li-ion battery
Carefully observe the following precautions for the rechargeable Li-ion battery (hereafter referred
to as “rechargeable battery”). If these precautions are not followed, overheating, leaking, or cracks
in the battery may result in an electrical short, explosion, smoke, fire, electrical shock, injury to
yourself or others, or damage to the product or other property.
 Use the rechargeable battery only for its intended purpose. Your printer and rechargeable
battery are designed to function exclusively with each other. DO NOT insert the rechargeable
battery into a different printer, or a different rechargeable battery into your printer, otherwise a
fire or damage may occor.
 To charge the rechargeable battery, insert it into your printer, and then use the AC adapter or
Car adapter designed specifically for this printer.
 DO NOT charge the rechargeable battery near a fire or in direct sunlight. This could activate the
protection circuitry, which is designed to prevent danger from high heat. Activation of the
protection circuitry could cause charging to stop, charging to occur with excessive
current/voltage if the protection circuitry fails, or an abnormal chemical reaction within the
battery.
 When charging the rechargeable battery, use the battery charger designed specifically for the
rechargeable battery.
 DO NOT allow wires or other metal objects to come into contact with the terminals of the
rechargeable battery. DO NOT carry or store the rechargeable battery with metal objects such
as necklaces or hairpins. This could cause an electrical short, and lead metal objects such as
wires, necklaces, or hairpins to overheat.
 DO NOT use or leave the rechargeable battery near a fire, heaters, or other high temperature
(above 176F/80C) locations.
 DO NOT allow the rechargeable battery to come into contact with or to be immersed in water.
 DO NOT use the rechargeable battery in corrosive environments, such as areas where salty air,
salt water, acids, alkalis, corrosive gases, chemicals, or any corrosive liquid is present.
 DO NOT use the rechargeable battery if it is damaged or leaking.
 DO NOT directly solder any connections to the rechargeable battery. This could cause internal
insulation to melt, gas to be emitted, or safety mechanisms to fail.
 DO NOT use the rechargeable battery with the polarity (+) (-) reversed. Check the orientation of
the rechargeable battery before inserting it, and do not try to force the rechargeable battery into
your printer. Charging the rechargeable battery with the polarity reversed could cause an
abnormal chemical reaction within the rechargeable battery or abnormal current flow during
discharge.
 DO NOT directly connect the rechargeable battery to a household electrical supply.

DANGER
 Liquid (electrolyte) leaking from your printer or rechargeable battery may indicate that the
rechargeable battery is damaged. If the rechargeable battery leaks, immediately stop using your
printer, unplug the AC adapter, and isolate your printer by placing it in a bag.
DO NOT touch the electrolyte. If electrolyte gets in the eyes, do not rub them. Immediately rinse
liberally with tap water or other clean water and seek the advice of a medical professional. If left
alone, the electrolyte could cause eye damage. If electrolyte contacts 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 a 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 your 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.

The available scientific evidence does not show that any health problems are associated with
using low power wireless devices. There is no proof, however, that these low power wireless
devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency
energy (RF) in the microwave range while being used. Whereas high levels of RF can produce
health effects (by heating tissue), exposure of low-level RF that does not produce heating effects
causes no known adverse health effects. Many studies of low-level RF exposures have not found
any biological effects. Some studies have suggested that some biological effects might occur, but
such findings have not been confirmed by additional research. RJ-2030/2050/2140/2150 have
been tested and found to comply with FCC radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure Guidelines.
