General Fault Isolation

Power-Up Self-Test

Poor Quality ECGs

3-2
See the MAC™ 800 Operator's Manual, Chapter 2, "Equipment
Overview: Getting Started" to verify operation.
On power-up, the system automatically runs an internal self-test. If all
circuit tests pass, you will see the start-up screen.
The next screen that appears after the start-up screen depends on the
Power Up mode selected in System Configuration. The Resting ECG
mode is the default Power Up mode.
If the equipment is not working properly, ask the following questions.
Is the unit turned on?

Have there been any changes in the use, location, or environment of

the equipment that could cause the failure?
Has the equipment hardware or software been modified since last

use?
Is operator error the cause of the problem?

Try to repeat the scenario exactly and compare that to the proper
operation of the equipment described in the manual.
Is the battery installed?

When connected to the AC wall outlet, does the green AC power light

glow?
Poor quality ECGs can be caused by factors in the environment,
inadequate patient preparation, hardware failures related to the
acquisition module, lead wires, cables, or problems in the unit.
