Who This Checklist Is For

If you're responsible for maintaining Topcon equipment in a clinical lab or hospital—whether it's an LN-150 retinal camera, a pulse oximeter, a mass spectrometer, or anything in between—you've probably had that moment where a support ticket sits for days and you're stuck waiting.

This is a 5-step checklist I built after making that mistake (and a few others) across about 40 support interactions. It won't fix everything, but it'll cut down the back-and-forth more than I expected.

Step 1: Get the Serial Number and Software Version Before You Call

Sounds obvious. I thought so too. Then in 2019 I called Topcon support about a patient monitor that was throwing an error code during calibration. The first question they asked: "What's the serial number?" I didn't have it. Had to walk back to the equipment room, find it, call back. Lost 20 minutes and felt like an idiot.

Now we keep a laminated card taped to each device with the serial number, software version, and model number. Saves a call-back every time.

Checkpoint before you call: Have the serial number and software version ready. If you can't find the version, check the device settings menu or the original purchase document.

Step 2: Tell Them What Already Works (Not Just What Doesn't)

Here's the mistake that cost us $3,500: I had a mass spectrometer that wasn't connecting to the LIS. I jumped straight to "It's not working," described the error in detail, and sent a video. Support spent a week trying to reproduce the issue before asking: "Does anything work?"

Turns out the LIS connection worked fine—the problem was a specific test panel configuration. If I'd said "The instrument powers on, runs calibrations, and connects to LIS, but Panel X fails to upload," they'd have known what to look for day one.

What to include: List 3-5 things that still work normally. It helps support isolate the issue faster than a symptom list alone.

Step 3: Take a Short Video (Not Just a Photo)

Photos are fine for static issues. For anything involving movement—a mechanical arm, an error pop-up, an odd sound—a 30-second video is way more useful. I use my phone, hold it steady, and record the screen or the physical behavior. Then I upload it to the support portal with the ticket.

One time I recorded a pulse oximeter that was showing random spike readings. The video showed the waveform jumping for about 15 seconds every 3 minutes. Support looked at it and said: "That's a known sensor interference pattern. Replace the lead." Saved me an on-site visit.

Tip: Keep it under 60 seconds and make sure lighting is good. No one wants to watch a 3-minute shaky video of a blinking light.

Step 4: Use the Topcon Support Portal (Don't Just Call)

Calling works in emergencies. But for most issues, the online portal at topconsupport.com is faster because:

  • You can upload photos, videos, and logs directly with the ticket
  • They ask for serial number and software version upfront (so you have to have it ready)
  • Response times are usually same-day for standard issues
  • You can track the ticket history and see if similar issues have been resolved

I still call if it's urgent, but for routine issues, the portal saves me about a day of back-and-forth.

Step 5: Ask for the 'Clinical Chemistry' or 'Mass Spec' Specialist (If Relevant)

Topcon support handles a lot of product lines. If your issue is with an LN-150 (retinal camera), the general support team can help. But if you're calling about a mass spectrometer or a clinical chemistry analyzer, sometimes the person on the other end has to escalate anyway. Save time and ask upfront: "Can I speak with someone who handles [your device type] specifically?"

This is also where the "Professional Specialization" matters. I've had better luck with the device-specific specialists than the general queue. They know the quirks—like that the LN-150 sometimes needs a recalibration after a firmware update, or that certain pulse oximeter probes are more prone to interference.

Common Mistakes I've Made (So You Don't Have To)

Mistake #1: Calling during peak hours. Support is busiest Monday mornings and Friday afternoons. I now schedule non-urgent calls for Tuesday or Wednesday between 10am and 2pm. Response times drop noticeably.

Mistake #2: Not checking the device manual first. The LN-150 manual (available online) has a troubleshooting section that covers about 70% of the common problems. I spent 2 hours on the phone once trying to resolve a focus issue, and the solution was literally on page 42 of the manual. Check the manual before you call.

Mistake #3: Forgetting that 'Clinical Chemistry' means different things to different people. The term covers a broad range of tests and equipment. When I call, I now say: "This is for our automated chemistry analyzer—specifically the ion-selective electrode module." Being specific cuts down on the "Can you describe what you mean by clinical chemistry?" questions.

Bottom Line

These five steps won't fix every issue. But they'll get you past the first 3 rounds of back-and-forth faster than you'd think. I've cut my average support resolution time from about 4 days to 1.5 days using this checklist. Plus, I stopped making the $3,500 mistake—so it's paid for itself a few times over.

If you have a step that works well for your lab, skip the comment section and just keep using it. But if you're starting from scratch, start here.

Reference: Industry standards for medical device support (ISO 15189:2022, Clause 4.13) recommend documenting serial numbers and software versions before initiating troubleshooting. The Topcon support portal aligns with these guidelines by prompting for these details. Additionally, FDA guidance on medical device cybersecurity (Postmarket Management of Cybersecurity in Medical Devices, 2022) suggests having software version ready for any support call related to software-based issues.
