HY-03DTD Fitting & Configuration
Enabling Dial Tone Disconnect on the HY-03
On the rear panel of the HY-03 is a set of 4 DIP switches These switches are used to configure the HY-03 in the modes
that you want it to operate A label on the top panel of the unit shows the orientation of the switches :
Figure 1-1 : Configuration Settings Switches
To enable the dial tone disconnect option, set switch SW1 to ON When enabled (ON), the HY-03 will automatically
disconnect from the telephone line when an appropriate dial tone is detected
Configuring the Dial Tone Disconnect oard
To configure the dial tone disconnect board, the appropriate jumper(s) JP1-JP16 on the Dial Tone Disconnect PCB must
be fitted to enable detection of the required tone(s) in the country in which the HY-03 is being used, or for the equipment
to which the HY-03 is to be connected For example, to enable the HY-03 to detect the dial tone in Finland, set the
jumpers for JP1, JP2 and JP3
