so after you scan the package, BIG ARROW DOWN and then ENTER ?
The DIAD follows a logic chain.
Package scanned, stop info entered (i.e. consignee, room, floor), big arrow down.
This gets the package sheeted, or attached to the stop. You can add more, or an infonotice if non-delivery.
Now you select what the status of the package will be for the stop. Press deliver, RelNumber or CIR, then select a release location. If a signature is required, then the DIAD will
not allow you to continue without obtaining a signature.
Press

. Stop complete.
Eventually you will be able to do this blindfolded in 5 seconds using only the buttons (yellow toggle button comes in handy).
