Notes for Safe Operation
(1) Be sure to use the Graphtec-supplied AC adapter. In environments where there is a lot of noise or where the
power supply is unstable, we recommend that you ground the GL220.
(2) When a high-voltage signal cable has been connected to the main unit's analog signal input terminal, avoid
touching the leads of the input terminal's signal cable to prevent electrical shock due to high voltage.
(3) Ensure that the GL220's power source is positioned so that it can easily be disconnected.
4.
Notes on Functions and Performance
(1) Be sure to connect the main unit to an AC or DC power supply that conforms to the rated range.
Connection to a non-rated power supply may cause the main unit to overheat and break down.
(2) Do not block the vent on the main unit.
Continued operation with the vent blocked may cause the main unit to overheat and break down.
(3) To avoid malfunctions and other damage, avoid using the GL220 in the following locations.
• Places exposed to high temperature and/or high humidity, such as in direct sunlight or near heating equipment.
(Allowable temperature range: 0 to 45°C (0 to 40°C when a battery pack is mounted), Allowable humidity range:
5 to 85%R.H.)
• Locations subject to excessive salt spray or heavy fumes from corrosive gas or solvents.
• Excessively dusty locations.
• Locations subject to strong vibrations or shock.
• Locations subject to surge voltages and/or electromagnetic interference.
(4) If the main unit becomes soiled, wipe it off using a soft, dry cloth. Use of organic solvents (such as thinner or
benzene) causes deterioration and discoloration of the outer casing.
(5) Do not use the GL220 in the vicinity of other devices which are susceptible to electromagnetic interference.
(6) Measured results may not conform to the stated specifications if the GL220 is used in an environment which is
subject to strong electromagnetic interference.
