Hi Trent. Yes, I now have three Motorola VFD handsets. Two Dynatac 6000 series handsets, one of which has an audio fault, and the other one on this Dynatac 4000 phone. I am now trying to get the Dynatac 4000 to work properly, so far it will not register with my test set at all. Have tried a few more things & will re-test it tonight. I really need a handbook though ! None of the usual Motorola keypad sequences work with this phone, to change the system, etc. The NAM cannot be programmed on this one with the handset, is too old for that ! It uses a 82S123 bipolar PROM chip for the NAM data, this can only be written to once. Needs an external PROM programmer to change any of the NAM data. There is a data port on the front of the transciever unit, under a cover, but I believe this was only used to upgrade the firmware in the phone, and for testing perhaps.
Hi Thomas. Fantastic ! Look forward to seeing the manual. These are pretty rare models alright. Does your 4000 have the exact same type of handset cradle as mine ? Or is it the slightly later version with the up down push buttons on it ? My unit is definitely faulty. Have you tried powering up your one ? Cheers, Chris.
Hi Thomas. If your handset cradle unit is the same type as my one, then just add your photos to my Dynatac 4000 entry. If it is different, then I suggest creating a separate entry for it. So you are missing the transceiver to cradle cable & the power cable ? Cheers, Chris.
