Replacing the Touch Memory/Timer Module
The Touch Memory/Timer module has an internal Lithium battery.
Eventually, this module will need replacement. Please refer this task
to qualified service personnel. The original module has been secured
to its holder with RTV sealant. Take the time to renew this sealant
after a new module is installed.
The instrument Date/Time must be reset when a new Touch Memory
is installed. See page 9.
Preventive Maintenance
Under average conditions, the SDA 601 should receive preventive
maintenance every 2000 hours. This is approximately one year of
operation. Preventive maintenance includes cleaning, visual inspec-
tion, a performance check and, if necessary, calibration. See the Ser-
vice manual for performance verification and adjustment procedures.
CAUTION. The SDA 601 case is made of molded plastic. Do not allow
water to get inside any enclosed assembly or component. Do not
clean any plastic materials with organic cleaning solvents—benzene,
toluene, xylene, acetone, or similar compounds—because they may
damage the plastic.
