Why does my Ceia PD240CH Metal Detector alarm after start-up?
- NNicholas RuizAug 6, 2025
If the Ceia Metal Detector gives an alarm signal right after you turn it on, it might be due to starting it up too close to metal. Try moving the detector away from any metal and then reset the detector. Also, electromagnetic sources nearby could be the cause. Use a hand-held metal detector with a different operating channel.
