Do Graphiclite fluorescent lamps contain mercury?

Yes, fluorescent lamps contain mercury. Please dispose of according to federal, state, and local regulations.

I have power interruptions in my area. Can I use an Uninterrupted Power Supply (UPS), like I use on my computer, with the light booth?

No! This type of power supply is actually a DC battery with a circuit that imitates AC voltage. It will damage the electronic ballasts used for the fluorescent lamps.

My Graphiclite® light booth never “turns off”. The LiteGuard II is always on when the rest of the lights are off. Shouldn’t it turn off completely?

No. This indicates that power is being supplied to the unit and it is ready to use. If local safety requirements state that equipment must not have power connected to it when not in use or when the business is closed, insert a surge protecting power strip (not an Uninterruptible Power Supply) between the unit and the main power source.

The LiteGuard II monitor information does not display correctly, what should I do to correct this?

Do not hit the RESET button! Small voltage spikes or fluctuations can cause microprocessor-controlled devices (such as the LiteGuard II) to exhibit minor display anomalies. This is a common problem for companies that use heavy machinery or equipment that use a great deal of electrical power, or in industrial areas of a city. To correct this, simply unplug the unit from the main power, wait five seconds and then plug it in again. If the problem continues to occur, place a surge protecting power strip between the main power outlet and the light booth. DO NOT use an Uninterruptible Power Supply (UPS) or battery back-up device, as is sometimes used with a computer. These can damage the electronic lamp ballasts used in the light booths. If the problem continues to occur after installing the surge protector, call GTI Graphic Technology, Inc. – your unit may need servicing (888-562-7066 Eastern Time).

Can aides be used inside the booth?

Yes. Some industry practices require the use of viewing aides, such as transparency viewers and monitor displays. These should all be the same color as the booth (i.e., Munsell N8), not interfere with the lights by casting shadows on the print to be viewed, and should be easy to remove. GTI offers viewing aides, such as transparency viewers and articulated monitor stands, in a number of sizes to fit its wide variety of viewing booths.
