Battery Disposal
WARNING.
To avoid personal injury, observe the proper procedures for handling
lithium batteries. Improper handling can cause fire, explosion, or severe burns.
Do not recharge, crush, disassemble, heat above 100
°
C (212
°
F), incinerate, or
expose the battery to water.
The DSO module contains one lithium battery, A1U70, located on the Processor
Board (A1). Battery replacement is accomplished by installing a new Processor
Board (A1). Read the following information before replacing the battery. See
Processor Board on page 6--13 for replacement instructions.
Dispose of lithium batteries according to local, state, and federal regulations.
In the United States, you can typically dispose of small quantities (less than 20)
of batteries with ordinary garbage in a sanitary landfill. You must send larger
quantities by surface transport to a hazardous waste disposal facility. Package the
batteries individually to prevent shorting. Then, pack them in a sturdy container
that is clearly labelled: Lithium Batteries — DO NOT OPEN.
Inspection and Cleaning
This section describes how to inspect for dirt and damage, and how to clean the
DSO module. Inspection and cleaning are done as preventive maintenance.
Preventive maintenance, when done regularly, may prevent malfunctions and
enhance reliability.
