I am stuck and am hoping someone here can be of assistance. We have a client that WE installed a PBX and TVA-50 for back in July 2012. Their owner had a copy of the critical information as did we. We cannot at present locate that document and surprisingly the other copy is nowhere to be found. The responsibility for ensuring this was available is of course ours regardless of who else maintained a copy and as a result I am here hoping there is an rs-232 method similar to some other devices for resetting the TVA-50 without losing the programming. Short of that forcing a backup without said password would be helpful. System Manager mailbox password is also *sigh* MIA.

Please PM me for my number if you prefer to discuss over the phone.
