- Confirm USB seating and panel power stability.
- Reboot panel only if required by site procedure.
If Wi-Fi programming app cannot connect
- Verify HSM3WIFI LED/state per quick start (if applicable).
- Disable mobile data — some phones route away from panel Wi-Fi.
- Move installer device within 3 m of panel during initial pairing.
If trouble persists after removal
- Recheck USB port for debris or bent pins.
- Refresh keypad trouble display
[*, 2]and wait one status cycle. - Verify no other USB accessory remains connected.

FAQs
Can this stay plugged in permanently?

Normal while adapter is inserted — indicates USB accessory detected.
Is this still an active product?
DSC published a discontinuation notice — plan alternate Pro programming methods for new installs.

Hardwired IP path, DLS via communicator, or current dealer cloud commissioning tools.
