Just press buttons to change settings such as kind, size and body position. Paper saving recording: You can check the stability of waveforms by the display before recording with the built-in thermal array recorder. Automatic grid printing lets you use economical plain paper. Compact body: Compact and weighing less than 6 pounds for portability and space savings.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Noisy ECG / lead-off
HighSymptoms: Baseline wander, muscle or AC noise, "lead fail", poor 12-lead quality.
Root cause: Poor skin prep, dried or lifting electrodes, or a worn patient cable / lead set.
Will not acquire or analyse
MediumSymptoms: Acquisition hangs, no interpretation, or a self-test failure.
Root cause: Acquisition-module fault or a software issue.
Printer / recorder fault
MediumSymptoms: No or faint report, paper jam, misregistered grid.
Root cause: Thermal print head, paper handling, or (older units) the stylus.
Battery / power fault
MediumSymptoms: Short battery run time, will not hold charge, will not power on.
Root cause: Aged battery pack.
Connectivity fault
LowSymptoms: ECGs will not transmit to the ECG-management system / EMR.
Root cause: Network / Wi-Fi / modem configuration or the communication module.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Noisy ECG / baseline wander / lead-fail
- Re-prep the skin (abrade, degrease) and fit fresh electrodes.
- Secure the lead wires and route them away from mains cables and other equipment.
- Swap in a known-good patient cable / 10-lead set.
- Check the acquisition-module connection at the cart.
- Confirm a clean 12-lead on an ECG simulator; replace the cable or refer the acquisition module.
Symptom: Will not acquire, analyse or print
- Confirm a lead set is connected and all leads are on.
- Check the thermal paper is loaded correctly and clean the print head.
- Print the internal test pattern / grid.
- Reboot the cart; note any self-test error.
- Refer the acquisition module or the writer / print head as isolated.
Symptom: ECGs will not transmit to the management system / EMR
- Confirm the Wi-Fi / LAN / modem settings and the destination address.
- Send a test ECG and read the error.
- Reseat the communication module / SIM.
- Confirm the ECG-management system is receiving from other carts.
- Escalate a server-side or account issue to IT / the vendor.
Symptom: Short battery run time / will not power on
- Charge fully and run a capacity test if supported.
- Check the charger and DC input.
- Replace the battery pack when below the service limit.
- Confirm run time and a full print cycle on battery after replacement.
- Refer the power supply if it will not power on with a good battery.
