Risk level

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

If G2Call+ shows "I have not seen any icon change" while pairing a Golmar ART 4W LITE/G2+ or ART 4WH/G2+ monitor, confirm the unit is the Master monitor (M), reset Wi-Fi parameters until the AP icon appears, and hold the phone within 10 cm with audible volume.

Safety first

Stop and check this first

  • Do not disconnect mobile data on your smartphone or reject G2Call+ permissions for storage, camera, microphone, telephone or location: Golmar warns that rejecting permissions or turning off mobile data prevents proper app operation and pairing.
  • Do not share the temporary administrator QR code (valid for 30 minutes in the G2Call+ Share menu) with unauthorised people, and never remove the monitor from its wall bracket while system power is connected.

Safe checks you can perform

  • Confirm that the unit is the Master monitor (M) on the About screen
  • Reset Wi-Fi parameters on the monitor and verify the AP icon
  • Repeat the acoustic tone transfer within 10 cm with raised phone volume

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Verify Master role (0550), AP mode and G2Call+ acoustic or manual pairing
  • Do not attempt this professional task: Inspect the rear QR/UID label or wall mounting with power disconnected

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Verify Master role (0550), AP mode and G2Call+ acoustic or manual pairing

    What they doThe technician confirms the ART 4W LITE/G2+ or ART 4WH/G2+ monitor is set as Master (0550), resets Wi-Fi parameters until the AP icon appears, checks app permissions and mobile data on the smartphone, and supervises tone pairing within 10 cm (or manual selection using the 12-character UID and 8-capital-letter password).

    They must show youthe monitor Wi-Fi icon changing from AP to connected and the monitor listed on the G2Call+ Devices home screen.

    In writingmonitor UID, connected SSID, configured call transfer delay (00 to 45 s) and outcome of the G2Call+ registration.

  2. Inspect the rear QR/UID label or wall mounting with power disconnected

    What they doIf the rear QR code label (12-character UID and 8-capital-letter factory password on the back of the monitor) must be read or the 2-wire bus connection inspected, authorised personnel disconnect system power first, record the label data and re-secure the monitor on its wall mounting bracket.

    They must show youthe monitor secured on its wall mounting connector and the call forwarding icon active on the main menu.

    In writingverified UID and factory password check, bracket seating and confirmed call transfer to the G2Call+ app.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Confirm that the unit is the Master monitor (M) on the About screen

    No special tools

    Who:
    you, checking the Settings menu on your Golmar ART 4W LITE/G2+ monitor.
    How:
    wake the main menu, enter the system settings screen and open the About screen to confirm the monitor is configured as Master (M) rather than Slave (S1, S2 or S3).
    Result that matters:
    verify Golmar's requirement that only the master monitor in an apartment can activate Wi-Fi transmission.
    If the About screen shows S1, S2 or S3:
    perform Wi-Fi pairing on the apartment's Master monitor (M) or ask the installer to review codes 0550-0553.
    If the About screen confirms M (Master):
    proceed to check AP mode on the Wi-Fi menu screen.
    Evidence to keep:
    role letter (M, S1, S2 or S3) and monitor address displayed on the About screen.

  2. Reset Wi-Fi parameters on the monitor and verify the AP icon

    No special tools

    Who:
    you, on the Settings \ Wi-Fi screen of the Master ART 4W LITE/G2+ monitor.
    How:
    enable the monitor's Wi-Fi functionality, run Reset Wi-Fi parameters as Golmar recommends on first startup, and check that the AP pairing icon appears at the top right of the Wi-Fi configuration screen.
    Result that matters:
    place the monitor in AP mode before scanning the QR code or entering the UID and password manually in G2Call+.
    If the AP icon is visible at the top right alongside the UID:
    start the Add device flow in G2Call+ while keeping mobile data active.
    If the AP icon is not shown:
    reset the Wi-Fi settings on the monitor again and wait for the AP icon to appear.
    Evidence to keep:
    visibility of the AP icon and 12-character UID on the monitor's Wi-Fi menu screen.

  3. Repeat the acoustic tone transfer within 10 cm with raised phone volume

    No special tools

    Who:
    you, holding your smartphone with the G2Call+ app beside the ART 4W LITE/G2+ or ART 4WH/G2+ monitor.
    How:
    keep mobile data enabled and accept all G2Call+ permissions (storage, camera, microphone, telephone, location); at step 7 increase the smartphone audio level to at least the audible minimum and hold it less than 10 cm from the monitor while it sends tones until the monitor icon changes from AP to the Wi-Fi signal icon.
    Result that matters:
    complete the acoustic credential transfer and enable call forwarding on the monitor.
    If the monitor Wi-Fi icon changes from AP to connected and you tap Save:
    verify the connected SSID and call transfer delay (00 to 45 s).
    If "I have not seen any icon change" persists despite holding the phone within 10 cm:
    ask a technician to inspect the monitor and Wi-Fi setup.
    Evidence to keep:
    icon change from AP to Wi-Fi coverage and the SSID displayed on the monitor's Wi-Fi menu screen.

  • No he visto ningún cambio de icono
  • Wi-Fi icon does not change from AP

What it means

Golmar's G2Call+ App Manual (TAPP G2Call+ G2+ Rev. 0122 V02) and the ART 4W LITE/G2+ Monitor Manual explain that, in step 7 of initial Wi-Fi registration on ART 4W LITE/G2+ and ART 4WH/G2+ monitors, the smartphone sends Wi-Fi network credentials through acoustic tones until the monitor's Wi-Fi icon changes from AP to connected, displaying "I have not seen any icon change" if the icon does not update. By contrast, ART 7W/G2+ obtains an IP address automatically. This message alone never proves that the monitor is defective.

Warnings and stop conditions

  • Mediumsource verified

    Do not disconnect mobile data on your smartphone or reject G2Call+ permissions for storage, camera, microphone, telephone or location: Golmar warns that rejecting permissions or turning off mobile data prevents proper app operation and pairing.

  • Highsource verified

    Do not share the temporary administrator QR code (valid for 30 minutes in the G2Call+ Share menu) with unauthorised people, and never remove the monitor from its wall bracket while system power is connected.

Symptoms and causes

Probable causes · in order

  • Smartphone volume too low or distance over 10 cm during tone transferCommon

    With ART 4W LITE/G2+ and ART 4WH/G2+ monitors, the G2Call+ app sends network details using acoustic tones and requires raising smartphone audio to the audible minimum within 10 cm of the monitor.

    Evidence: Manual de la aplicación G2Call+ G2+ / G2Call+ App Manual (TAPP G2Call+ G2+ Rev. 0122 V02)

  • Monitor not in AP mode or Wi-Fi parameters not reset before pairingCommon

    The G2Call+ manual warns that if the monitor is not in AP mode (AP icon at the top right of the Wi-Fi configuration screen), adding the device is impossible and Wi-Fi settings must be reset.

    Evidence: ART 4W LITE/G2+ Monitor Manual (TART 4W LITE/G2+ Rev. 0322 V02 EN) · Manual de la aplicación G2Call+ G2+ / G2Call+ App Manual (TAPP G2Call+ G2+ Rev. 0122 V02)

  • Monitor configured as Slave or mobile data switched off on the phonePossible

    Only the master monitor (special code 0550, shown as M on the About screen) can activate Wi-Fi transmission, and Golmar instructs users not to disconnect mobile data during G2Call+ pairing.
