GRE500 and memory loss

[Helion]

How long does it hold the data in its memory after batteries are removed and the AC adapter is unplugged?
My BC256T only has 15mins before it looses it all.

I don't believe it requires power to keep things in memory.

How long does it hold the data in its memory after batteries are removed and the AC adapter is unplugged? . . .

From Appendix D - General Specifications in my PSR-500 Owner's Manual (and likely yours):

Memory backup — No backup battery required, utilizes non-volatile EEPROM memory

Your BC246T looses all its memory in 15 minutes??

The BC246T should keep all settings for years with no power applied. Maybe he meant a different, very old model.

Exactly what I was thinking... thats why I was confused and asked.

Yes, the BC246 Trunktracker III looses its data when AC and batteries are removed. I found that
out the hard way. I had to recharge the NimH batteries in an external charger, and I couldn't find
the AC adapter right away. When I plugged in the AC about 15 - 20 mins later the scanner was blank.
When I got back home I reloded the data from ARC246 and I was back in business.
I have not tried to reproduce this, but I will. I want to know if the memory is faulty.
The scanner works fine otherwise.

The memory in the BC346T is non-volatile. Your programming should last 5-10 years (or longer) with no batteries installed and AC power disconnected.
