How to: Emergency updates for PAB-devices

About PAB-device emergency updates

An emergency update for a PAB device is only necessary if your PAB device (Doser, Powerbar, KH Director, etc.) becomesĀ unresponsive after a PAB device firmware update attempt. If your PAB device becomes unresponsive and is no longer detected by your master device (ProfiLux or Standalone Doser), follow these steps to recover your device.

If you have a native Standalone Doser (switched to Slave mode) being controlled by a ProfiLux or SA Doser…read this!

Even though your “now slave” Doser is being controlled by a ProfiLux or SA Doser, it is still a native Standalone Doser. That means your doserĀ must be recovered by following the emergency update steps for a Standalone Doser.
