The PRO-76 was a simple, no-frills scanning receiver manufactured for Radio Shack by Uniden in the early 2000s.
The PRO-76 has some features and test modes that can be accessed by holding down various keys while turning the radio on. None do anything particularly interesting (to me), but maybe others will find these useful.
| Keys | What It Does |
| 2-9 | Shows “Clear” on the screen and clears memory. |
| 2-9-SCAN | Shows “Load” on the screen. When the “Load” message is gone, Channels 1-15 are replaced with test frequencies. |
| 2-9-PROG | Shows “000 00” on the screen. Pressing the up and down keys changes the hexadecimal value on the screen. Unclear what this does. |
| 2-9-MON | The same as 2-9. |
| 2-9-PRI | The same as 2-9-SCAN. |
| 2-9-DELAY | The same as 2-9-PROG. |
| 2-9-L/OUT | Does a limit search on 173.0 – 173.1. |
| 2-9-ALERT | Clears the memory, but if the radio is already cleared (all memories are zeroed out), it flashes “ALERT” on the screen. |
| 2-9-KEYLOCK | Starts weather search mode. |
| 2-9-HOLD | Clears the memory. |
| 2-9-. | Shows “H WIRED” message on the screen. |
| 2-9-0 | Performs display test. When E is pressed, it loads test frequencies into memory. (If the radio is turned off at this point, no test frequencies are loaded.) |
| 2-9-E | Same as 2-9-0. |
| L/OUT | This lets you configure the beep that plays when you press a key. Normally, when you turn the radio on with this key held down, it displays “NO BEEP” before going to the regular scan mode, after which the radio will not beep when you press keys on the keypad. To turn the beep back on, press it again and it will say “ON BEEP.” The beep will be restored. |
