# My NaI Probe wont turn on

## A few checks

First, check the USB cable is plugged in properly to your RayMon or laptop/PC.

Then, try plugging the detector into a different USB slot in the laptop/PC if the NaI Probe is not being picked up.

Also ensure the USB-C insert of the cable is plugged properly into the NaI Probe itself. 

Try out a different cable, and ensure the cable you are using is less than 1m.

If your NaI Probe will still not turn on, do not hesitate to get in touch with our service team by [submitting a service ticket on the Kromek Customer Portal.](https://help.kromek.com/customer-portal?hsLang=en)
