Another old system I'm trying to set up - a Strata XIIe analog system. Everything seems to initialize OK, and there are no problems under the System Test Procedure and EKT Functional Checks. But when I move onto some other programming and cycle power to set that in memory, the date/time reverts to default.

I thought it was a bad battery on the CCAU daughterboard of the HCAU, but that checks out at 3V (about 3.5V) just the way it should. And the SET LED shouldn't light if the battery setup isn't right, but it does light.

I bring this up in part because I seem to be losing other programming also, but the date/time is clearly lost so I'm looking at that as the canary in the coal mine.

While I'm at it, if someone is reading this who still knows analog Toshiba equipment: The EKT 6000 series phones all have a slide switch under the snap-off cover that surrounds the line jack on the base. The switch sets to either "Head Set" or "Ext. I/O" and I cannot find any documentation about it. I have phones set either way for no clear reason. Anyone know what it's for?

Oh boy it was a long time.
I remember there is a jumper for the Battery. Check it out. Should shorted ON side. SET light would be up if HCAU operates properly. Has nothing to do with battery.

My books are packed ,but it seems to me there was a procedure to save your programming at the end,like release the red button and cycle the power.

Someone asked the same question about a week ago about the switch.The book didnt reference it and I'm not thinking anyone answered the question.

Do you have the books on this,as we are talking
1982- 1986 system.

I have the manuals for this I will check them out and see what they say.

Vad60: Yes, the jumper is shorted ON.

KenB: Yes, that is the stated save-program procedure -- release the red button and cycle power. That's when the date/time reverts to default.

probably time for an upgrade. Isnt that system over 20years old?

My WAG is the battery or processor maybe power supply.

Those old XII And XX"s show up on e-bay every once in a while . You may get spare parts that way. Also look at Harris /Lanier as it was the same product .The XXe has many of the same cards.

You could also find a dk40 or 280/424 same place and put PEKU cards in it,if you dont mind the box change.

If your just puttzing around with this change the battery and see if it improves.

Since that Toshiba could be around for the last 20 -21 years ,anything could have happened along the way.

there is a procedure that you need to do to secure data in working memory.There are two ways of doing this. If the system is not in service release the set switch and rock the power, If the system is in service and you don't won't to drop any calls depress the following keys in the order given on staton 17, Spkr #, * , 9 , Int , CO 1, CO 4, CO 5, CO 8, CO 9, CO 12, CO 13, hold, this code secures the data into working memory without dropping any calls, release the set switch.

This post is kind of late. If this is a Rel 1 system (HKSU801) then the time will not be saved under a power down. You need a rel 2 (HKSU805) the do this. The switch on the ekt6000 phones is a mystery switch, (for use on Mars only)

Thanks for ID'ing the "mystery switch" on the ekt6000 phones.

Concerning the loss of date/time when cycling power: As far as I can tell this is an HKSU805, though I don't see that stamped anywhere, and who knows if there was some mixing and matching on components over the years. It's good to know that loss of date/time was standard behavior under Rel 1. Maybe I haven't got a problem there after all. I now observe that other system programming is preserved through a power cycle.

One thing still to figure out though: On Sta 10, key 00 does not give me Intercom. It gives me CO 1 instead. It does this with any phone swapped in. Replacing the original HCAU with another used one (newly initialized) does not help. I started Prg 410 with defaults of LED 00, 05 and 10 on, and played some with assigning other key patterns, but I never got key 00 to act as Intercom. What should I look at?
