In the Hydra - Atlantis image the procedure seems to be as follows:
1. Go to the channel you want to set up and bring up the control panel [blue], then select Softcam, and Sm@rtkey.
2. Select the required Softcam and press [Green] to make it the current Cam.
3. Use the arrows to move down to one of two buttons marked [Sticky]. The first is the channel, the second is the provider. Presing [OK] on one of these makes it stick for either this channel, or all channels by this provider. The button text changes to [Unstick] when selected.
4. repeat above for all channels...

HTH :-)
