TO ENSURE SAFETY

This Service Manual has been compiled for the purpose of facilitating repair and maintenance of the 
GL450/400/350 midi LOGGER by Graphtec service personnel and other persons who have undergone 
equivalent technical training.
Maintenance or repair by unauthorized service personnel is to be strictly avoided. Because the 
GL450/400/350 contains numerous internal components with a high electric potential, such work by 
unauthorized service personnel could cause human injury or serious damage to the GL450/400/350 midi 
LOGGER.
