2.3 LCD Screen
The display will vary according to the current task being carried out. In all screens
however, the top and bottom lines always display the same information: the top line
displays system information, and the bottom line always gives the softkey options.
The following is an example of a typical resting ECG screen.
Items 1, 2 and 3 are in the same position for all screens.
(1) Top line - time, date, patient name, and current power source - mains (u), or bat-
tery (
). When battery capacity is limited the battery symbol flashes.
(2) Data acquisition area or data entry area.
(3) Softkey designation. Pressing the key below the text carries out the function in-
dicated. The options available will change according to the screen displayed.
Items 4 to 10 are specific for ECG acquisition only:
(4) Current Heart Rate (averaged over 4 beats and refreshed every 2 seconds).
The HR is also given on a manual printout. Note that with an auto mode printout
the HR is averaged over the full 10 seconds of the recording.
(5) Electrode connections - when an electrode indication flashes (an audible alarm
is also given), it indicates that the electrode resistance is too high. The elec-
trode(s) must be reapplied.
(6) Sensitivity 5, 10 or 20 mm/mV. Change the sensitivity with the keys 3 (auto), 4,
5 and 6. An kAk in this box indicates that automatic sensitivity is selected (auto
mode printout only).
(7) Speed 25 or 50 mm/s. Change the speed with the keys 8 and 9.
(8) Lead indication (leads currently displayed on the screen). Change the lead
group with the < and > keys on the keypad.
