Since the IB-1 Kit looks like it uses a Fender 25.5 Inch Scale on it's neck, you can try using the following method to set the neck relief and the action at the 17th fret, firstly you will need the following tools:
* Allen Keys to fit the Truss Rod and Bridge Pivot-Posts.
* Phillips Head Screwdriver for removing the Truss Rod Cover.
* Capo to put just behind the first fret on the fretboard.
* Set of Automotive Feeler Gauges (make sure it has at least one marked .010 Inch).
* 300mm Steel Ruler.
Method:
Step 1, First make sure you have your guitar tuned up to pitch and that the bridge is sitting with it's base parallel to the front surface of the body, if it is angled a bit forward or backwards, then use the screwdriver to adjust the tension on the springs till the bridge is sitting parallel.
Step 2, Use the Steel Ruler to check the action at the 17th fret, you want a gap of at least 2.5mm between the top of the 17th fret and the bottom of the string for both the low and high E-Strings, use an Allen Key to adjust the two Bridge Pivot-Posts till the gap is 2.5mm.
Step 3, Next, making sure that your guitar is tuned up to pitch, put a Capo on the neck between the Locking Nut and the 1st fret, fret the low E-String at the 17th fret and use a .010 Inch Feeler Gauge to check the gap at the 8th fret, use an Allen key tighten or loosen the truss-rod till the .010 Inch Feller gauge just fits between the top of the 8th fret and the bottom of the E-string, and with the E -String just touching the feeler gauge, do the same for the high E-String, adjusting the tension on the truss-rod as necessary.
Hopefully that should get the neck relief adjusted correctly and then the fretted note at the 1st fret should be in tune.
