Press the number key on the keypad corresponding to the number of the quick key you have assigned. It the system was on then pressing the key turns it off. If the system was off pressing the key turns it on. For two digit quick keys (i.e 21) press the period key and then the two digits. You can see which ones are on or off by looking at the screen.
well quick keys for the systems are controled, after assignments, by the number kets. At the bottom of the radio displat you see numbers and or stars. Stars, the system is turned off, a number showing, its turned on. now for a specific system to turn it on, while leaving the others off, fastest way I have found is turn all systems off, then turn the one you want back on and you will scan only that system.. You can assign number keys to a specific channel/frequency which is another way to use quick keys. Its not really a quick key but it functions very similar. The subject of group keys, system keys, and number keys is read and read and read.
If a system Quick Key is enabled (active/turned on), then you'll see the number at the top of the display. If the system Quick Key is disabled (not active/turned off), then an asterisk would appear where the number would be.
As an example: A system has a Quick Key of 1. When SQK 1 is enabled (the system is being scanned), you'll see a "1" in the top row. If SQK 1 is disabled (the system is NOT being scanned), you'll see "*" in place of that "1".
yes, press hold, then you can toggle off all the keys, then toggle on what you want. you can stay in scan also if you desire. In Freescan, ctrl k brings up the quick key assignments. press auto select. The blue check marks are what is assigned to each key. Hover over a check mark and you will see what exactly is assigned to that key.Now if you want just that key active, torn off all the keys and turn on the one you want. You will end of scanning only one system which is active.
