Adjusting receiving sound volume
The receiving sound volume can be adjusted each telephone line by the semi-fixed volume
controls provided at both sides of the channel selector. When the receiving sound volume
is decreased by the line loss etc., adjust the semi-fixed volume controls by a flat tip
screwdriver so as to obtain optimum sound volume. The telephone line numbers to be
used correspond to the speech link numbers as shown the table below.
