GP-577RS Replacing the Backlight Handling Guide
Thank you very much for purchasing the GP-577RS replacement backlights. Be sure to
read the following Backlight Installation Cautions before attempting to change the
backlights . This replacement backlight package
If this backlight is not appropriate for your GP unit, or does not function correctly,
please contact your local authorized GP representative for instructions.
• Whenever changing the Backlight, be sure the GP's power cord has been
disconnected. When the GP's power cord is connected and the GP is ON, high
voltage runs through the wires in the backlight area—do not touch them!
• When the GP's power has just been turned OFF, the Backlight area is still
very hot! Be sure to wear gloves to prevent being burned.
• Since the backlight is made of thin glass, handling it roughly may cause it to
break ,therefore, be careful when installing the backlight not to either push or
pull it too strongly.
• Change the entire backlight unit, i.e. both the tube and holder.
• Do not allow water, oil or fingerprints to be left on the tube, since they
can all reduce the backlight's life.
