Having come upon this information, I thought I'd share it. Incidentally, the vendor offers a service manual for this product, priced at $19.95, available by special order from the same retail locations who offer the phone itself. When your phone is delivered, it has a five-digit 'security code' programmed into it. The factory default for this value is shown in your owners manual on page 12. The installer is encouraged to change this. You need this code to reset your total air time accumulator, to change your unlock code, or to enter programming mode. To enter programming mode, dial * 3001 # [SEL] 9. You are now in the install menu. Use the [END] key to scroll through the menu (there are about 14 items on the menu). At each step, the name of the administerable item appears in the display, along with its current value. The on/off toggles are toggled by pressing the [SEL] key. The numeric entries are changed by entering the desired value on the numeric keys. If you step through the entire menu, your display eventually shows: prog done. At this point, press [SEL] [CLR] to exit programming mode. The programming menu includes the following items: (I'm not sure what all of them mean; if you're not sure either, don't change them!) Many of these paramaters are set to values provided by your cellular service provider. The label field below is what is displayed, in mixed case, when you scroll into the field: If anybody can supply additional information on the fields I've indicated as ?? below, it would be appreciated. LABEL WHAT IT MEANS ===== ============= identif toggles between 'info pri' and 'info alt' This apparently selects whether the following steps are programming the primary or the alternate nam. ho id 5-digit numeric home system identifier access 1 digit ?? locl opr 1 digit ?? phon your ten-digit phone number st class 2 digits ?? paging ch 4-digit paging channel number o-load class 2 digits ?? pref sys A or B group id 2 digits ?? security 5-digit security code 1 date MMDDYY possibly the date of manufacture? 2 date MMDDYY the date of installation prog done Why are the date fields present? Are they used as a memo for future installers? How did I obtain the information above? I just bought one, and the field labeled 'pref sys' was set to the wrong system when it was delivered. The phone worked fine, but displayed ROAM when connected to its home system, and did not display ROAM when it happened to connect with the other carrier here. I called Radio Shack and described this symptom, and offered to either bring the phone back to them, or to let them walk me through re-programming it. They chose the latter!
