✅ Check the simple stuff first

Make sure the patient is safe — swap in a backup unit if you need to.
Reproduce the complaint yourself and write down exactly what you see (screen, alarm, code).
Check power, battery, cables, accessories, and settings before ordering parts.
Then open the service manual above and follow its troubleshooting section.

🛠️ Common faults for SURETEMP PLUS (7)

Battery indications source ↗

Blinking frame + 'b' arrow = battery out of range; single blinking segment = low
Replace batteries

'A' with arrow source ↗

Ambient outside 10–40 °C: move to normal room temp

Probe or instrument with an X source ↗

Probe X = probe fault, usually replace probe
Instrument X = internal fault; read code in Biotech mode Error Log

Reading out of tolerance (calibration check) source ↗

Verify with the 9600 Plus Calibration Tester (01802-110) or the SureTemp Calibration Key (06138-000)
Field repairs are limited to calibration check, probe/well, battery and unit replacement

Need software version or error log (Biotech mode) source ↗

692: place it in the wall holder; hold Recall while pulling the probe, then release
Recall steps through the categories (device/algorithm version, ID, error log); Mode or C/F changes values; returning the probe exits; times out after 5 min

Battery drains during cleaning or storage source ↗

Unplug the latching probe connector when removing the well; reconnect until it snaps in

Wrong probe or well, or probe damaged source ↗

Blue well for oral/axillary (02891-000), red for rectal (02891-100)
Probe kits: oral 02893-000 (4 ft) / -100 (9 ft); rectal 02892-000 / -100
Use only Welch Allyn covers (05031-750); biting the tip damages the probe
