Now, press the Standby button on the front of the PVR. The PVR will begin to start up and then you should see a sequence of numbers displayed on the front panel, beginning with the letters dn; this process usually takes less than a minute.
After the firmware file has been transferred, another sequence of numbers, beginning Ap, will be displayed, and at the end of this sequence, the message End will flash on the display.
You must not turn your PVR off until the End message has been displayed or your PVR restarts itself, otherwise you may damage it by interrupting the update process.
If there is an error transferring the firmware, you may see the letter E, followed by a number; if this happens, you should check that you selected the correct file for your PVR, and that the USB cable is correctly connected, before trying the firmware update again.
The firmware update program will not work if Altair or any other program that communicates with your PVR is running on the computer at the same time.
6.2.2 Installing a firmware update via a serial connection
The TFD Down application that is installed as part of Top- field’s Windows applications allows you to update the firmware on your PVR if you do not have a computer with a USB port. It works in the same manner as the USB version, but is slower, and you should use the USB update programme if possible.
