The carets show you whether top or bottom line is active. Target value could be in top line, bottom line, mode indicators (mostly above top line), channel numbers (to right of top/bottom lines), carets (to left of top/bottom line). If an instruction says "Repeat" something "until" something, repeat the operation as many times as necessary until you see the correct state on display as a bonus, the available settings will repeat in a loop so you don't have to catch the correct setting the first time and can see exactly what is changing on the display and which most closely resembles the desired setting (in case you are uncertain about which part of the display to look at). When entering one or two digits after menu as a shortcut to a specific menu item, type those digits quickly or radio will time out. In these instructions, is preceded by to make sure you are starting from the correct state (not in menu). In the example below, I put 146.850 in memory 126 replace those values wherever they appear with the desired ones. Also, even many licensed operators have difficulty programming these model radios even when trying to do something normal. In many cases, those who need to inhibit transmit the most (non-licensed operators) may be those least skilled in operating the radio. I have included very detailed instructions below. If you have inhibited transmit, display should not change in any way (unless you receive a transmission) other than the backlight may come on afterwards if it was off. It will also display the transmit frequency instead of the receive frequency if they are different but won't change if the transmit frequency is invalid. When actually transmitting, the display should change color to yellowish (depends on menu settings) and the signal strength icon should appear. The behavior while programming isn't quite what you would expect, and I initially thought I was unsuccessful, but it still appears to disable transmit. The method used was to set the offset and direction such that you were instructing the radio to transmit on 0Hz. I did apparently succeed in inhibiting transmit on a UV-5RA memory(reports Firmware version BFB297 but above BFB296 may not be updated with each revision) without using a computer.
