  For the static spherically symmetric dilatonic black hole described by the
Gibbons-Maeda-Garfinkle-Horowitz-Strominger geometry, we analyze the timelike
trajectories for electrically charged test particles. Both cases of an electric
black hole and a magnetic one are considered. Finally, we are obtaining the
solution to the Klein--Gordon equation in terms of Heun confluent functions and
the corresponding energy spectrum. A special attention is given to the role of
the dilaton parameter.
