I have two motorola xtn 446 there locked on the 1 station.
To program the radio:
1) Hold in the MON button and the PTT while turning the radio on, continue to hold the buttons in until the radio quits making noise.
2) Press the MENU button one time, this will take you to your FREQ. After selecting your FREQ
3) Press the MENU button again, select your CODE, press the menu button again
4) You will begin to walk through the other settings possible for the radio at each press of the menu button. Here are what you will see in no particular order:
4a) Hi Lo: this is a reference to narrow or wide band channel spacing. If you are in the US you should choose Lo as narrowband channel spacing is the newer FCC rules.
4b) A circle with a slash through it: This is your scramble feature. If you choose zero you have no scrambling.
4c) CH: This is where you tell your radio how many channels to have.
4d) Lock: Choose Y or N. This might be what you are referencing in your question. To unlock choose N for No.
4e) A face with wavy lines in front: This is mic gain. The normal setting is 2. However, if you have a soft or gruff voice you might want to choose 1 or 3 to compensate for the distortion heard on the other end.
4f) CA: This is call alert, which will cause a ring before you speak to alert the other radios users they have a call.
On each of these stops through the menu make your selection by using the + or - buttons, followed by pressing the menu button to lock in your new setting. ALL of your radios much match on all settings to work together correctly.
When you get to the end of the menu selections you will hear a different chirp. This will signal you are done. You can then shut off the radio and turn it back on normally to use it.
Each channel should accomodate upto 25 workers so if you program your radio for 4 channels, you will have enough radio workspace for 100 people. Typically most users do not need this much space, so it is advisable to keep your number of channels to a minimum, using only the ones necessary. It never hurts to have a second frequency just incase you run into traffic on your first one.
