Selecting and playing a specific message in an ISD1700

I am new to this product and would appreciate help. I am controlling the KA02 with an Arduino Uno. I want to record four messages and then to access a specific message. The recording is not a problem. I have looked at numerous sketches published on line. I have tried the chipset_xx commands but all of the examples utilize start and end address which are for the entire memory. Is there a way I can determine the address range for each of the individual messages? Also, do the message ranges remain constant if I erase and record a new message in one of the 4 “slots”?

hey, i’m also looking for a solution for the same question (problem)
, i’ve post a long time ago on this forum but no answer

do you 've an idea ?
