the first four characters are the computed crc and the second four are the operator assigned configuration name the first four characters are automatically assigned by the processor as the crc number corresponding to that configuration the second four operator assigned characters are assigned to the configuration actually becoming a part of the configuration the second set of four characters of the identifier would be the configuration name and could be for example the initials of the hospital area such as picu discussed above icu intensive care unit or or1 operating room 1 or others the use of an error detection routine such as crc combined with a configuration name result in it being very unlikely that two instruments which have the same identifier will not have the same configuration a continuation of the configuration menu can be obtained from the screen of fig6 a by pressing the 34 soft 34 key identified as 34 more 34 and indicated by the bar 180 as can be seen by reference to fig5 this particular bar is placed over the right most soft key 178 fig6 a also presents an organization technique in which each screen is given a unique code in the screen of fig6 a the code is.
