Since the KY-58 does not have an initiate button, how do you initiate when loading codes?

• A. The radio PTT must be keyed on the applicable radio
• B. Press the Initiate button on the keypad
• C. Turn the power cycle
• D. Hold both KY-58 keys simultaneously

Answer: (A)

Initiation of the loading process is triggered by the radio, not by a button on the KY-58. Since there is no Initiate button on the KY-58, you start loading by keying the Push-To-Talk on the applicable radio. This radio-side action signals the crypto device to enter the loading state and begin handling the crypto data for that channel. Power-cycling the device, attempting to press a non-existent initiate control, or holding KY-58 keys do not start the loading sequence. The PTT signal ensures the load occurs only when you’re actively transmitting on the correct radio path.
