Checking Software Version
Before you start, you need to make a note of the current version of software installed in the 840C. To do this:
1. Connect the 840C to the mains supply using an IEC power cord, making sure the voltage selector switch is set to the correct voltage for your local mains supply.
2. Switch the 840C on using the Power On/Off switch on the rear panel and the Standby/On button on the front panel.
3. When the 840C has switched on and is ready to be used (i.e. “No Disc” is displayed on the front panel LCD), press the “Menu” button on the front panel 4 times until “SOFTWARE VERSION XX / YYY / Z.Z” is displayed on the front panel LCD. XX is the DSP version number, YYY is the DSP build number and Z.Z is the PIC version number. Note down the full software version number.
4. Switch the 840C off using the Power On/Off switch on the rear panel.
Upgrade Instructions – PIC Software
To upgrade the 840C software, please carry out the following:
1. Install the 840C Loader Program onto your PC or Laptop (by following the on screen instructions), by unpacking 840C Loader Program.zip and running
