Consumers have expressed a need to limit unauthorized access to their radios. Reasons for this could be to limit undesired monitoring or access to a system. An answer to this request is a feature called Radio Lock. On power up, a radio with the Radio Lock feature enabled requires that the user enter a password before access to any of the other radio fea- tures is allowed. This includes transmit, receive as well as access to the radio menus. This password, stored in the radio's EEPROM, is composed of a variable numbers of digits with values ranging from 0 to 9. It can be programmed either directly by the user, assuming the radio is unlocked, or from the Radio Service Software. Hardware requirements to utilize this feature is a radio with a full keypad (0-9,*,#). Radios without a fit11 keypad cannot employ this feature.
