: If you are attempting to use a high-output consumer signal booster, ensure you are not causing interference with local cell towers. Always follow the specific installation instructions for the device you own.

Controls cryptographic states. Positions include PT (Plain Text), CT (Cipher Text), LD (Load Variables), and Z (Zeroize all keys instantly). Hand-tighten

Just let me know your intended audience (e.g., comm planners, operators, procurement) and whether you need a sample or a filled example .

Rotate the main function switch from to PT (Plain Text). Wait for the system Self-Test (BIT) to complete. Verify that no critical error codes display on screens. 3. Loading Cryptographic Keys Connect a Simple Key Loader (SKL) to the data port. Set the radio function switch to the LD (Load) position. Select the correct crypto keys on your SKL interface. Transmit the keys and verify the "Load Success" prompt. 4. Programming a Channel Press the MENU key on the front keypad. Select Preset Config using the arrow navigation keys.
