Press-Temp)
In the event of a malfunction this PCB should be replaced.
In the earliest instruments, instead of the two insulating envelopes around the PCB, there
is a piece of insulating foil under the PCB Press-Temp, which needs to be rein
stalled.

4.6 Troubleshooting tips
Instrument cannot be switched on
(in battery mode no image on screen and no beep when actuating On button.)
- Battery completely depleted, not connected, or defective:
connect up to mains for
charging; otherwise, check battery plug is O.K. and inserted correctly, if necessary,
replace battery
- Battery fuse SI 500 on PCB ECG Monitor defective:
inspect and, if necessary, replace
it after dealing with the cause
- Membrane keypad not plugged in correctly, or defective:
plug in correctly or replace if
required
- Display contrast is too weak, not plugged in correctly, or defective:
adjust contrast and
set it correctly; other wise, plug in display-foil connector correctly, if necessary, replace
- EPROM not plugged in correctly:
plug in correctly or replace if required
- PCB ECG Monitor defective:
replace PCB.
Cyclic start up failure
- If a cyclic start up is performed after switching on the unit (with a beep and a squared
pattern, with indication of version no., followed by the watchdog test with timeout), and
a normal screen does not appear, the backup battery may be depleted or not connec-
ted properly, so that its voltage falls below 2.5 V.
