We have some of these, I gather they are quite old, and we only have a user manual for them. Eng info may have long since disappeared.
If anyone has engineering info that they could share please, I'd be very grateful.
Presently one had failed, there's an SD card fitted which had 3 partitions on it, none of which had a recognisable file structure by the PC.
Another SD card (from a working unit and with similarly obscure file structure) was fitted, the Display showed lines going up/down denoting the locking / sync progress until it eventually locked up.
When fitting the original card, the display shows a flat line and no eventual freq lock up.
We'd like to duplicate the card for this and subsequent units, but it's contents are unreadable.
If theres any suggections / info about SW backup to SD or cloning cards, plus menus / engineer modes etc, I'd be very grateful, thanks
