3. Clockwise rotation of the tension rod adjustment will tighten the tension rod to correct a warped condition. Use the previously outlined procedure to check your adjustment. Make sure that you do not overtighten the tension rod and lose the clearance at the 5th fret. 4. Counterclockwise rotation of the adjustment nut will loosen the tension rod until the proper clearance can be seen at the 5th fret. SPECIAL NOTE: The Kaman Bar adjustment is very sensitive. One half turn on the nut when the rod is under tension will produce a significant change at the first fret, so turn it conservatively and check the neck frequently as you adjust it.
The preamplifier used in the Ovation Acoustic-Electric guitar obtains its power from a single, 9-volt battery found in the battery box inside the bowl. For optimum performance, we recommend using a 9-volt alkaline battery. Current is drawn only when a cord is plugged into the guitar, so frequency of battery replacement will depend on how often the acoustic electric feature is used. Always remember to unplug your guitar when not in use. This will extend the battery life considerably. Noise or distortion detected in the output is usually a sign that a new battery is required. Some Ovation guitars use the Ovation Thin Line piezo saddle pickup. Similar in operation to the original Ovation pickup, the vibration of strings over the saddle creates small changes in the pressure exerted on the six small piezo crystal elements located under each saddle section (one per string). This change in pressure on the piezo crystal causes an electrical charge to appear at the output terminals of each element. The output of each crystal is then added to the others resulting in an electrcal signal corresponding to the vibrations of all strings. As in all Ovations, this signal is amplified and processed with onboard electronics and finally connected to a P.A. system or amplifier. The Ovation Thin Line offers a more traditional look as well as the rugged construction which make Ovation guitars the guitars for use on the road.
Rear Access Models:
For Rear Access models, access is via the door in the back of the bowl. In all other respects proceed as for other Kaman Bar models. These models require a longer handle adjustment wrench, (#950059-X). Your Rear Access guitar has a screw in the center of the access door. Loosen the screw until the door can first be slid to one side, then to the other, to remove it. Take care not to completely remove the screw. Reverse the procedure to replace the door.
The Ovation Acoustic-Electric
Many Ovation Roundback guitars come with the now famous built-in acoustic-electric pickup and preamplifier system. Located directly beneath the Celcon saddle which automatically compensates for intonation, six piezo electric transducers amplify not only the vibrations of the strings from the top of the saddle, but also transmit their mechanical action on the guitar top.

To Replace The Battery:
Simply push the latch in the direction of the arrow and the battery holder will slide out. The box is designed to only allow the battery to fit in the holder in it�s proper position.
