The paper coninues investigations of the well-known class $T$ of typically real functions $f(z)$ in the disk $U=\{z\colon|z|<1\}$. The region of values of the system $\{c_2,c_3,f(z_1),f(z_2)\}$ in the class $T$ is studied. The region of values of $f(z_2)$ in the class of functions $f\in T$ with fixed values $c_2,c_3$ and $f(z_1)$ is determined.
