Dilatonic black hole dyon-like solutions in the gravitational 4d model with a scalar field, two 2-forms, two dilatonic coupling constants 
, 
, obeying 
and the sign parameter 
for scalar field kinetic term are considered. Here 
corresponds to a ghost scalar field. These solutions are defined up to solutions of two master equations for two moduli functions, when 
for . Some physical parameters of the solutions are obtained: gravitational mass, scalar charge, Hawking temperature, black hole area entropy and parametrized post-Newtonian (PPN) parameters 
and 
. The PPN parameters do not depend on the couplings 
and 
. A set of bounds on the gravitational mass and scalar charge are found by using a certain conjecture on the parameters of solutions, when 
, .
