Battery Safety

The Battery Packs used on Zebra Mobile Printers contain a great deal of energy and can cause personal injury or start a fire if used improperly or carelessly. Please observe the following safety practices:

Caution • Avoid accidental short circuiting of any battery. Allowing battery terminals to contact conductive material will create a short circuit which could cause burns and other injuries or could start a fire.

Caution • Batteries can explode or catch fire if improperly charged

or exposed to high temperatures or fire. Do not disassemble, crush or expose batteries to water.

Caution • Use of any charger not approved specifically by Zebra for use with its batteries could cause damage to the battery pack or the printer and will void the warranty.

Read carefully and always observe the safety guidelines for Li-ion batteries provided with each Battery Pack.

Charger Safety

Do not place the LI72-4 Quad Charger in locations where liquids or metallic objects may be dropped into the charging bays.

Use care in locating either the LI72 Single Charger or the LI72-4 Quad Charger. Do not block the ventilating slots on the top and bottom covers. Ensure that the Charger is plugged into a power source which won’t accidently be turned off if you will be charging batteries overnight.

Required Regulatory Text for Argentina

Only certified adaptors with the following electrical characteristics shall be used. The use of different adaptors could damage the device, present hazards to the user and declare the correspondent guaranty void.

LI72:	Input ratings: 100-240 VAC 50/60Hz 200mA., Class 2
