12ECG /RESP
（
HJ-500
）
Waveforms and numeric values are not displayed.
Cause : On the DS-5300, HJ-500 is set to OFF for the “MODULE
CONFIG.” in the preset menu.
Solution : Set HJ-500 to ON for the “MODULE CONFIG.” in the
preset menu of the DS-5300. For procedures, refer to the
operation manual for the DS-5300
ECG waveforms and numeric values are not displayed when 3-lead
cable is connected.
Problem : A baseline and a “LEAD OFF” message is displayed.
Cause : 5 or 10-lead cable is set for the lead cable type.
Solution : On the DS-5300, set the “HJ-500 3LEAD” to ON in the ECG
configuration menu.
CAUTION
When selecting 10 or 5-lead cable again, set the “HJ-500 3LEAD” to OFF.
Otherwise waveforms for 10 or 5-lead cable can not be monitored.
Chest lead is not displayed when 5(10)-lead is connected.
Problem : On the 12-lead display, ECG waveform is displayed for only
1 lead from lead I, II, or III.

Solution : On the DS-5300, set the “HJ-500 3LEAD” to OFF in the
ECG configuration menu.
Artifacts are interfering with the ECG waveform.
Problem : AC noise is interfering.
Cause : Electrodes are not attached properly. Electric blankets or
other noise generating factor is used near the patient.
Solution : Attach the electrodes properly. Verify that lead cables are
not damaged. Keep noise generating factors away from the
patient. Turn on the AC filter if necessary.
