Information firmware update Panasonic
+ change of the default password is required on the first login after the firmware update
+ devices are expected to be unavailable for 15-30 minutes during the firmware update and might auto-reboot up to 5 times during the process. No manual intervention is required.
+ handsets of TGP600 may lose their connection to the base station after its firmware update, thus should be checked manually. Once manually reconnected with the base, the handset will download the newest firmware version and install it automatically
