Testing the Generator
Turning on the generator initiates an internal self-test to verify the calibration and
the operation of the speaker, all indicators, the displays, and some internal
components.
To test the generator, follow this procedure:
1. Turn on the generator by pressing the front panel On (|) switch. Verify the
following:
• All visual indicators and displays on the front panel illuminate.
• Activation tones sound to verify that the speaker is working properly.
2. If the self-test is successful, a tone sounds. Verify the following:
• The macrobipolar and bipolar displays each show a power setting of one
watt.
• The seal display shows one amber bar illuminated.
If the self-test is not successful, an alarm tone sounds. A number may
momentarily appear in the bipolar display and, in most cases, the generator
shuts down. Note the number and refer to Chapter 7, Responding to System
Alarms.
If you removed and/or replaced the battery, alarm number 105 may appear in
the bipolar display when you turn on the generator. If this happens, calibrate
the generator.
Confirming Outputs
Use this procedure to ensure the accuracy of the generator. Always confirm the
output
• After calibrating the generator
or
• Every six months
Warning
Use the generator only if the self-test has been completed as described.
Otherwise, inaccurate power outputs may result.
