GENERAL PRECAUTIONS

Your GL2200 is ruggedly constructed to give many years of reliable operation. However, you will

extend the life of the console and preserve its cosmetics by applying these simple common sense

precautions.

• Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions

where it is likely to be subject to vibration, dust, dirt or moisture.

• Do not use any liquids to clean the control surface of the console, a soft dry brush or dry lint-free

cloth is ideal.

• Use only water or ethyl alcohol to clean the trim and scribble strips. Other solvents may cause

damage to paint or plastic parts.

• The faders, switches and potentiometers are lubricated for life. The use of electrical lubricants on

these parts is not recommended.

• Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors,

high power electric cabling): this may cause degradation of the audio quality due to induced

voltages in connecting leads and chassis. For the same reason, always site any external power

supply away from the unit.

SAFETY WARNING!

Mains electricity is dangerous and can kill. Mains voltage

is present within the console power supply.

Do not remove the power supply cover with mains

electricity connected. To ensure your safety, mains earth

is connected to the chassis through the power lead. Do

not remove this mains earth connection.

To avoid the risk of fire, replace the mains fuse only with

the correct value and type as indicated on the power

supply unit.
