Before you carry out the update please ensure whether your IS-1000 actually requires it: only units with a serial number lower than 59047 need to be updated to be used with the IS-1000 Control App.
Please ensure that the mini-USB cable you are using is working properly before starting the update.
Who has a serial number above 59047 can check the their firmware version installed on the apparatus by pressing the SKC (Single Knob Control) and turning on the Master Switch on the rear panel, the current version of the firmware is 222.
