Eclipse Operating Instructions
POWER-UP DEFAULTS
The fields in this menu affect paper speed and waveform printing. The settings in this
menu are in effect whenever the Eclipse Premier is powered on with the On/Standby
key. When changes are made in the POWER-UP DEFAULTS menu, changes go into
effect the next time the Eclipse Premier is powered on.
NOTE: These settings also can be temporarily modified by pressing
the "7," "8" and "9" machine control keys to change the settings for
Speed, Gain, and Filter, respectively (see "The Keyboard" on pg. 3-1).
Changes remain in effect until the unit powers down.

Determines the amplitude of printed and displayed waveforms.
150 Hz
40 Hz
Sets the upper frequency response.
Selecting 150 Hz provides the highest fidelity recording and should be used when
little or no noise is present.
The American Heart Association's 1990 Recommendations (Recommendations for
Standardization and Specifications in Automated Electrocardiography: Bandwidth
and Signal Processing) pertaining to high-frequency response for both adult and
pediatric recordings are met or exceeded when using the 150 Hz setting.
Selecting 40 Hz will reduce the muscle tremor and patient movement artifacts in the
ECG recording. It will result in a smoother looking trace at the expense of losing
some of the fine detail. This filter is applied only to the printed report and displayed
ECG. The data analyzed by the measurement and interpretation software is not
affected when using the 40 Hz setting.
