Safety & Warnings
The manual provides the following safety warnings and precautions:
1. Although the color pattern generator itself does not contain high voltages, the equipment being tested usually does. Always follow the safety recommendations of the equipment manufacturer.
2. Some equipment may be wired as a “hot chassis” type. Equipment using two-wire power plugs should be considered suspect, including those with polarized plugs. Never touch the chassis of “hot chassis” type equipment to avoid the possibility of a serious, possibly fatal electrical shock.
3. Avoid unnecessary exposure to high voltage; only remove housings and covers when necessary.
4. Familiarize yourself with the equipment being tested and the location of its high voltage points. Be aware that high voltage may appear at unexpected points in defective equipment.
5. Never work alone. Someone should be nearby to render aid if needed. Training in CPR (Cardio-pulmonary resuscitation) is highly recommended.
