New times of minimum light: HJD 2451157.5434, HJD 2451189.3872.
New light elements:  
$$\begin{array}{r@{}r@{}l}
{\rm Pri.\ Min. = HJD\ }2445962.3062 & {} + 0\fday9098488 & {} \times E.\\
                         \pm 0.0002 &      \pm 0.0000001 \\
\end{array}$$
$O-C$ diagram with respect to the new elements is plotted in Fig.~1.,
corresponding times of minima are available in electronic form through 
IBVS Web site.\\
Our observations suggest, in accordance with the previous photoelectric 
measurements by Zhang et al.\ (1985, 1987), that V541~Cas 
should be classified as a short-period Algol. The depth of primary and 
secondary minima of V541~Cas are equal within the observational errors, 
therefore the choice of reference epoch in the above given elements is 
arbitrary.}
