2.4. User and Group Settings

(1). Pre-configured user call numbers or group numbers, with number + username (or group name) indicated;

(11). Pre-configured communication groups (similar to trunking intercom channels);

(12). Groups can be switched via buttons, or the device can be configured by scanning the QR code on the device with a mobile phone.

2.5. Intercom Badge Buttons

(1). Uses touch-sensitive buttons with button indicator lights;

(13). 4 touch buttons: Call (for dialing, answering incoming calls, and hanging up), Up (scroll up, or volume +), Down (scroll down, or volume -, long press for mute), Display (switches display content; each press cycles to the next view, showing incoming/outgoing call numbers or received message notifications);

(14). 3 physical buttons: the power button on the back (long press to power on/off), the PTT intercom button on the upper side, and the SOS emergency button on the lower side, which triggers audible and visual alarms and dials a preset number; during point-to-point calls, a single press of the PTT button mutes the microphone.

2.7. Contacts Display Interface

In non-point-to-point communication mode, pressing the call button activates the contacts display. The up/down arrow buttons can be used to select numbers one by one, and scrolling to the top or bottom turns the page. After selecting a number, pressing the call button initiates a point-to-point call. If a group number is selected, pressing the call button prompts that the terminal has entered the corresponding group, and the PTT button can be pressed to speak.

2.8. Point-to-Point Call Interface

During point-to-point communication, the display shows: local number, called/calling number, caller/callee name, call status (incoming/outgoing), call type (internal/external), and call duration. When the call ends, the display returns to the normal interface.
