• Battery chargers may become warm during operation, but not hot.
If it becomes hot to the touch, unplug it from the power outlet
immediately and discontinue its use.
• Use of a non-recommended attachment to a battery charger may
result in a risk of fire, electric shock, or injury to persons.
• Make sure the battery charger power cord is located so that it will
not be stepped on, tripped over, or subjected to damage or stress.
• An extension cord should not be used with any battery charger
unless absolutely necessary. Use of an improper extension cord
could result in a risk of fire and electric shock. If an extension cord
must be used, make sure that:
• The pins on the plug of the extension cord are the same number,
size, and shape as those on the plug of the charger.
• The extension cord is properly wired and in good electrical
condition.
• The cord size is 18AWG for lengths up to 100 feet and 16AWG
for lengths up to 150 feet.
• Do not operate any battery charger if it has received a sharp blow,
has been dropped, or has been damaged in any way; take it to a
qualified service technician.
• Do not disassemble a battery charger; take it to a qualified service
technician when service or repair is required. Incorrect reassembly
may result in a risk of electric shock or fire.
• Maximum ambient temperature around the power supply or
transformer of any battery charger should not exceed 40°C (104°F).
• The output power from the power supply or transformer must not
exceed the rating given on the Desktop Dual-Pocket Charger.
• The disconnection from the line voltage is made by unplugging the
power supply from the AC receptacle.
• To reduce risk of electric shock, unplug any battery charger from
the outlet before attempting any maintenance or cleaning.
