Copyright TEL Encrypted Radio Programming and Service Manual
The module IND (status) output is fed to the SENSE-1 input to the radio micro. This allows the 
software to display the status on the LCD accessory annunciator. 
Encryption code control is achieved by keypad entry. Encryption Mode can be assigned to a 
function key when the radio is programmed or through a menu. (On most radios, this function is 
user-programmable.) This can be a long or short press of any valid function key, usually a long 
press of Function-2 key.
