1. Because it seems I didn’t mention the #18 in the last mail, I think the device is still in your site,
- If you can repair it by replacing the MB which we gave you, please send the failure MB to us.(Annotations the MB is from NETWORK FAIL)
- If you can’t, please send the whole device back to us.
2. About the #19/#20, we will send back to you today.
3. Please let us know others NBR223C/CCT-B01 if it has been repaired by replacing MB.
