33、D” to leave programming mode at any time. The mobile station shaii leave programming mode after a reasonable period of inactivity. When a user has reached the authentication key programming mode and scrolled to the appropriate MIN, the user may p r o w the authentication key by pressing the six to t
34、wenty six digit number provided by the d e r . The display shall show the digits of the ented number as the user is in the process of keying in the complete number. If the user makes a mistake he may clear all or part of the entered number by using the “clear” button. When the complete digit sequenc
35、e has been keyed, the user shall press “store“. “store” to store the number. At this point the mobile station shall validate the authentication key based on the check sum. If the key is valid, the display shall provide positive acknowledgment, such as the word “OK”, and the phone shall return to its
36、 n o d operating mode. If the key is invalid, the display shall provide negative feedback, such as the word “invalid”. At this point the user shall re-enter the number and continue the process until the authentication key is stored correctly. 2.1.5 Programming the Authentication Key at Installation
37、Mobile stations may also be programmable at the time of installation through the normal NAM programming mode. Manufacturers may implement this programming capability however they see f i t . There is no need for a user interface standard in this a r e a because it is presumed that NAM programming wi
38、ll be done by a qualified technician with access to the manufacturers instailation and service directions. Mobile stations shall allow NAM programming t o be completed without entering an authentication key, in order to allow carriers to implement user programming programs. Mobile stations without d
39、isplays or the required keys for user programming shall provide means for programming the A-key at the time of installation. 2.2 Revising the Authentication Key New Authentication Keys Overwrite Old From time to time the authentication key in a mobile station may require revision. if a new key is re
40、quired, it would be entered using the same process as described above, and shall overwrite the existing authentication key in the mobile stations memory. 2.3 Access to the Authentication Kev No Access to the Authentication Key Once an authentication key is entered, it may not, under any circumstance
41、s or in any mode of operation, be viewed through a mobile stations display or through any device attached to the mobile station. This includes the authentication key and NAM programming modes and any test modes as well as normal operation.
