# Access The Web GUI

  1. Find the label with UCM ID and PIN code on the back panel of Dryer.
  2. Open the Web browser.
  3. It is two main ways to access the Web GUI.
  • Way 1. Use the UCM ID to create a link with .local hostname like http://UCM_ID.local.
    For example: http://02CCF660F6.local.
    Web GUI - UCM ID Link
  • Way 2. Use the IP address of Dryer.

Note

mDNS must be enabled to resolve .local hostname.
