• From the FG terminal at the rear side of GLC unit, be sure to use exclu-
sive type grounding (resistance of less than 100
Ω
).
• GLC input and Output signal lines must be separated from the power
control cables used for any and all operation circuits.
• If this is not possible, use a shielded, grounded cable.
• Before changing the Backlight, be sure the power cord has been discon-
nected from the power supply
• While the unit is still hot, be sure to use gloves to prevent burns.
• Do not touch the backlight area while the unit is still ON, since high voltage
runs through that area.
• When the GLC's power cord has just been unplugged, the unit is still very
hot. Be careful not to be burned.
• Check that you have the proper Backlight for your specific GLC-
100 model.

unit's operation instructions.
