What does 'No top sender' or 'No bottom sender' mean on my Garnet Monitor?
- M
  Melinda GrantSep 10, 2025
  If your Garnet Monitor displays 'No top sender' or 'No bottom sender', it means that the display has been programmed for stacked senders and the top sender has been connected. The display has been programmed for double-stacked senders and one of these error codes are showing: • ntP - only the bottom sender is working and the top one is not. • nbo - only the top sender is working and the bottom is not. Correct the programming on the sender.
