To unlock your Radio Shack Pro-70 Scanner, you can try the following steps:
- Turn off the scanner by pressing and holding the "Power" button until the scanner turns off.
- Press and hold the "Func" button while turning on the scanner again. Keep holding the "Func" button until the scanner finishes its power-up routine and the display shows "Program."
- Use the number buttons to enter the four-digit unlock code. If you don't know the unlock code, try entering "0000," which is the default code for many Radio Shack scanners.
- Press "E" to confirm the code. If the code was entered correctly, the scanner should now be unlocked and you should be able to access all functions.
If the above steps do not work, try resetting the scanner to its factory defaults. To do this, turn off the scanner, then press and hold the "2," "9," and "MAN" buttons while turning on the scanner again. Keep holding the buttons until the scanner displays "Factory Test." Press the "Func" button to confirm the reset.
If none of these steps work, it's possible that there is a hardware issue with the scanner and it may need to be serviced or replaced.
