The BodyTrace scale uses a secure cellular network to automatically send your weight to the app, requiring no Wi-Fi or Bluetooth setup. This guide provides quick fixes for common issues, including troubleshooting connection failures, inaccurate readings, and resolving Error Codes (Er). For optimal results, use the scale on a hard, flat surface and try weighing in near a window.
⚠️ Error Codes & Troubleshooting
| Error Code | What It Means | What You Can Do |
|---|---|---|
| Er 1 | Battery is low | Replace all four AA batteries with fresh Duracell AAs. |
| Er 2 | You moved during measurement | Stand still and don’t talk while the scale takes your weight. |
| Er 3 | Weight exceeds the scale’s limit | This scale supports up to 397 lb (180 kg)—step off and use a different scale if needed. |
| Er 4 | No cellular coverage | Move near a window or to an area with better AT&T/T-Mobile signal, then try again. |
| Er 5 – 6 | Cellular or data transmission failed | Step off, then step on again in a spot with stronger signal. |
| Er 7 | Internal device error | Replace batteries. If Er 7 returns, note your 15-digit serial number (on the back) and contact support. |
| Er 9 | Provisioning (setup) error | Try another weigh-in. If Er 9 appears again, send us your serial number so we can fix provisioning. |
| Er 10 | Subscription on this scale is suspended | Send us the 15-digit serial number from the back so we can reconnect if needed. |
| Er 11 | Subscription on this scale is terminated | Send us the serial number so we can reconnect the scale. |
❓ Scale FAQs
🔴 Why do I see red dashed lines instead of a weight?
The scale is trying to send your measurement but can’t find a signal.
To fix:
-
Move near a window or to better signal.
-
Step on and wait for your weight to display.
-
Step off—it will attempt to send (dashes will spin).
-
When the screen goes blank, you’re done.
⚖️ Why is my weight different each time?
Minor variations (0.5–1 lb) are normal. They can come from:
-
Slight movement
-
Low batteries
-
Data syncing delay
To confirm:
-
Stand still on a flat, hard surface.
-
Wait for the number to flash.
-
Step off (dashes = sending; box = success).
-
Check the Vida app in ~10 minutes.
🗑️ How do I delete a weight I recorded by mistake?
-
In the Vida app, tap Weight on Home.
-
Tap History.
-
Swipe left on the entry and tap Remove.
If you don’t see Remove, message us the date & weight—we’ll delete it.
📏 What’s the maximum weight this scale supports?
Up to 397 lb (180 kg). Anything above may show an error or fail to sync.
🔁 How do I switch from kilograms (kg) to pounds (lb)?
-
Remove all four batteries.
-
Reinsert them to reset.
-
If it still shows kg, send us your 15-digit serial number so we can update it remotely.
