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.
Inaccurate temperature readings
HighSymptoms: Readings run low or high vs a reference, inconsistent between scans.
Root cause: Dirty sensor lens, poor technique (not scanning the full temporal path or over hair), diaphoresis, or ambient outside range.
Display diagnostic fault (HI / LO / HI A / LO A / bAtt / Err)
MediumSymptoms: "HI"/"LO" (target out of range), "HI A"/"LO A" (ambient out of range), "bAtt" (low battery), blank (dead battery), "Err" (processing error).
Root cause: Out-of-range target or ambient, low/dead battery, or an internal processing error.
Will not power on / short battery life
MediumSymptoms: Blank display, will not scan.
Root cause: Depleted 9V battery (single screw battery cover).
Wrong temperature scale
LowSymptoms: Reads in the unexpected unit (C vs F).
Root cause: F/C switch inside the battery compartment set to the wrong position.

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: Readings inaccurate
- Clean the sensor lens per the manual.
- Scan straight across the forehead to the hairline and, if the head was covered or the patient is sweating, also behind the ear.
- Confirm the room temperature is within range and let the scanner equilibrate.
- Verify against a reference thermometer.
- If it still reads wrong, restart; return to Exergen if an error persists.
Symptom: Display shows a code
- "bAtt" / blank - loosen the single screw, replace the 9V battery.
- "HI A" / "LO A" - move to a room within 16-40 C and let the unit equilibrate.
- "HI" / "LO" - re-scan; the target is outside 16-43 C.
- "Err" - restart the scanner.
- If "Err" persists, return the unit to Exergen for repair.
