surrounding area, observing the following guidelines:

1. Make sure that there are no other power supply cables, control lines, 

telephone leads or other equipment near the unit.

2. Make sure that there are no radio receivers or television appliances.

3. Make sure there are no computers or other control systems.

4. Make sure that there is no-one with a pacemaker or hearing aid in the 

area around the unit.

environment. In certain cases additional protective measures may be 
required.

CAUTION: WHEN HALOGENATED SOLVENTS OR DEGREASING AGENTS 
ARE PRESENT, THE MATERIAL TO BE CUT SHOULD BE CLEANED PROPERLY
