TO ENSURE SAFETY
This Service Manual has been compiled for the purpose of facilitating repair and maintenance of the WR1000
Series Thermal Arraycorders by Graphtec service personnel and other persons who have undergone equiva-
lent technical training.
Maintenance or repair by unauthorized service personnel is to be strictly avoided. Because the WR1000
contains numerous internal components with a high electric potential, such work by unauthorized service
personnel could cause human injury or serious damage to the recorder.
