headset model.
58.Can the headset be taken away during the firmware
update?
We recommend that you not undock the headset during the firmware update.
59.What should I do if the upgrade fails due to accidental
operations during the firmware update?
If the update fails, Yealink USB Connect will prompt the device is currently in recovery mode. Download
the corresponding firmware package from the technical support website and then manually update the
firmware.
If Yealink USB Connect does not prompt you to manually upgrade the firmware:
For WH66/WH67: unplug and plug the power adapter five times. The base enters the recovery
mode after the startup.
For WH62/WH63: power off the base, and then press the PC button, Teams/voice assistant button,
and phone button simultaneously while powering on. The base enters the recovery mode after the
startup.
