Chattanooga Continuum
Chattanooga · Model Continuum
1+1 Function: Continuum features 2 separate channels that can be managed independently. Users can select either the same program on both channels, or 2 different programs to be used simultaneously Individually tailorable: Continuum has 13 preprogrammed and 2 custom regimens for NMES and TENS Generating a strong contraction: Continuum uses balanced waveforms that deliver muscle stimulation that is powerful whilst remaining comfortable Hand switch: The handheld remote trigger can be used to easily activate stimulation, either by the clinician at a distance, or by the patient Heel switch: When placed inside the user's shoe, this optional heel switch can be used to trigger muscle stimulation Battery powered: Continuum runs on a pair of standard AA batteries
Key tips
- ·Most "no output" stim-unit complaints are cable-side - check electrode/lead continuity before assuming a unit fault.
- ·Frame and strap wear on mechanical rehab equipment is a real fall/injury risk - don't defer it as cosmetic.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Electrode / pad wear
LowSymptoms: Poor stimulation, skin irritation.
Root cause: Adhesive/surface wear.
Lead wire fatigue
MediumSymptoms: Intermittent stimulation, no output on one channel.
Root cause: Repeated flexing at connector.
Intensity control fault
LowSymptoms: Output won't adjust, stuck at one level.
Root cause: Potentiometer or control board wear.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Frame and strap wear inspection
- ·Electrode lead continuity check
- ·Annual electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electrode / pad wear
- Confirm the presentation - typically poor stimulation, skin irritation - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: adhesive/surface wear.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the tENS / stim electrodes per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
