Introduction
Before applying power to the recorder, complete these preparation tasks.
ATTENTION
Never move the pen arms when the unit is operating unless adjusting the pen alignment as
described in Section 8.
WARNING
SHOCK HAZARD
When the unit is powered a potentially lethal shock hazard exists at the AC line connections at TB1 on
each printed circuit assembly (behing the chart plate). Make sure the unit power is disconnected before
starting the procedure. More than one switch may be required to de-energize the recorder.
Failure to observe this precaution can result in exposure to a potentially lethal shock hazard.
