This is how it is supposed to work:

1. Find a pair of Walkie-Talkies.
2. Attach 9V battery to them.
3. Right mouse button on transmitter -> select frequency on what you want to talk. (pressing Next or Previous)
4. Right mouse button on transmitter -> press ON on selected frequency.
5. Press “comma” (,) or “colon” (.) on your keyboard to change your “direct communication” to “radio frequency” what you selected before.
6. Press “caps lock” to talk with other people on the same frequency.

Everything is good until we come to step 5. You just can not select “radio frequency”. Communication method stays on “direct communication” and you can not change it to whatever else.

Have tried rebinding communication selection keys to different keys, still doesn't work.
Also batteries which we are using are pristine and fully charged (you can lick them to test the charge).
