To put the BCT8 into remote mode, follow these instructions
1. Turn radio on
2. Press and hold the ". / RMT" key for 2 seconds or more. The radio displays "RMT OFF" or the current speed (bps)
3. Press the "UP ARROW" or "DOWN ARROW" keys to select the desired speed (57,600 bps is what I use)
4. Press the "E" key to make the selection. The radio returns to normal display mode
