I know this is an off topic info msg but thought might be of interest
to some of you. I just bought the latest Radio Shack AT&T house phone. It is progrmable and uses no batteriest to hold the settings in tack. It had features like 4 pre programale instant memories M1 M2 M3 that you can put in things lile "911" or 10-10-220 or Time check nr etc. You can set announcement after 2 rings then it can store up to 19 incoming msgs or 29 minutes of calls. I was bale to setup most of the features myself except the Annoncement after 2 rings. I went back to radio schack and told them I could'nt change the nr of rings to 2 followed by my announcement. they said bring the phone in and they would do it for me. I thought "oh no if I unplug the AC adapter I'll loose all the stuff I had set up. But they said no "it has a batteryless chip in it that retains the set up features without power of any kind!!! In fact the box it came in says "battery less" phone. So I took it down and the guy did it for me so fast I could'nt see which keys he was pokeing. Now its set for 2 rings only instead of 7 rings prior to the automatic announcement. he said the phone reqjuires no battery power to retain the "setup" contents. I wonder what kind of chip can do this:: ROM or RAM??? ROM CHIP requires a burner RAM chip reqyures some kind of battery backup lithium or whatever. But this Home Ph had neither. It says right on the box that it came in "batteryless phone"... How can this be???????? Joe |
