Changing The Crystal IC
To ensure proper operation of the PROG-MOD oscillator
the crystal IC must be inserted in the correct position. Pin
1 of the crystal IC must be inserted into the Pin 1 position
of the 14 pin DIP package marked with a yellow triangle
and make sure all pins are properly fitted into the 8 pin
socket.
The frequency required is selected by means of
links LK1 located on the module.
