Hopkins, it is ok if there is separation between the two pieces.
Go to "set"
Depress the left button for at least two seconds. If audibles are engaged you will hear the beep. It should display Set 1 once accomplished.
To make adjustments in Set 1 you will again have to depress the left button for apprx 2 seconds. This will allow you to make adjustments within Set 1. The right button will scroll through your setting options, using the left button to activate or lock them in. Once you have set all parameters for Set 1, computer will go to Set 2, and so on. To engage any of the Set 1-5 functions depress the left button as mentioned before. Note these buttons can be a little stiff in the beginning, so firm pressure is advised. They will loosen up a little with use.
If this still does not help you, please take it to a Mares authorized dealer for inspection and possible service.
Sincerely,
