Identifying Storage Problems (Options #A05 or 
StressWriter only)
The following table shows symptoms and solutions to problems that can occur when 
storing an ECG.
Table 6-3: Storage Problems and Solutions (Options #A05 or StressWriter only)
Message Likely Cause Possible Solutions
ECG too noisy to store Poor electrode contact. 
Dry or dirty electrodes.
Lead wires may be pick-
ing up interference from 
poorly grounded equip-
ment near the patient.
Patient cable is too close 
to the cardiograph or 
other power cords.
Use new electrodes. 
Abrade skin. Reapply 
electrodes. Check expira-
tion date on disposable 
electrodes.
Route lead wires along 
limbs and away from 
other electrical equip-
ment. Fix or move poorly 
grounded equipment.
Move the cardiograph 
away from the patient. 
Unplug the cardiograph 
and operate on battery 
power. Move other elec-
trical equipment away 
from patient. Unplug 
electric bed.
“Storage system full” 
message appears when 
fewer than 30 ECGs 
are stored.
Storage memory gradu-
ally wears out after many 
thousand store/erase 
cycles.
Consequently, ECG stor-
age capacity decreases 
gradually over the life of 
the product.
If under warranty, call 
service. Generally, stored 
ECGs are retrievable. If 
remaining ECG storage 
capacity is unacceptable, 
call service.
