Tool Preparation

Eject pin

Procedure

1. Use the eject pin to press and hold the RST button on the EMMA for 10s to 60s to reset passwords.
   • WiFi AP password
     The login password of the WiFi AP is reset to the initial one. You can obtain the initial password (PSW) of the WiFi AP from the laser-engraved silk screen on the EMMA.

     In some scenarios, the laser-engraved silk screen on the EMMA may be blurred or erased. Therefore, password-free login is supported within 3 minutes after the WiFi AP password is reset.

   • Passwords of local installer and user accounts

     The login passwords of the local installer and user accounts are reset to the initial ones. You can log in to the local commissioning screen to reset the login passwords.
