I recently acquired a Flex 6500 from a private individual and believe that I am the third owner of the unit. How can I find out if the two hardware upgrades (PENs?) have been applied to this transceiver? The serial # is: 2816 5312 6500 3677. Thanks.
Good to know although I just experienced a problem yet again that I have always had but only occurs once in a great while. The radio locks up, no movement on the panafall and then it screeches loudly. It does not respond to the mouse or keyboard and must be shut down by holding the on/off button for several seconds. I'm running the latest release of ver 1 SW and the machine runs just fine otherwise. This is NOT a fan noise BTW. Any thoughts? Jim
