An encoded symbol reader for reading a two-dimensional encoded symbols is provided with a register for registering function setting values, which determine functional settings of the encoded symbol reader, a first non-volatile memory for storing the function setting values; and a second non-volatile memory for storing initial values of the function setting values. When a first predetermined data is received, the function setting values are transferred from the register to the second non-volatile memory. When a second predetermined data is received, the initial values are read from the second non-volatile memory and sent to the register.
