For all units having serial number <56802 it is necessary to update the unit for the first time at your GN dealer or GN authorised service.
Before updating the unit please verify your PH-10 actually needs it. With the Master Switch of the rear panel turned OFF, push and hold the front panel SKC rotary switch knob, then, at the same time, turn the Master Switch on the rear panel ON. The display will show the installed firmware version. If it’s not the V153 or the display does not show anything the unit should be updated.
If you have problems with the firmware check, look at this tutorial on our Youtube channel.
After the registration you will be able to download the firmware update package and PDF guide in a single compressed file that needs to be extracted. The file contains both the firmware and the instructions for the upgrade in English, German and Italian both for Mac OS and Windows.
Please verify the mini-USB cable necessary to connect the PH-10 to the computer and the USB ports work properly before starting the update.
Do not reset the PH-10 if the computer does not show the unit as a common USB memory flash drive once connected otherwise the PH-10 memory will be completely erased making a factory re-booting necessary.
