SERVICE NOTES:
This model has section that does not share a common ground with the power supply section. The different sections
are referred to as HOT section and COLD section in the precautions below.
1. Do not touch the HOT section and the COLD section at the same time. You may receive an electric shock.
2. Do not short the HOT section to the COLD section. This could blow the fuse or damage parts.
3. Never measure the HOT section and the COLD section at the same time when using tools such as
oscilloscopes or multimeters.
4. Always unplug the unit before beginning any operation such as removing the chassis.
