The buttons on the keypad are not in the same position as the source buttons on the
Delta-88. While the sources are connected to the correct inputs and PCT-8 ports, the
source buttons, reading left to right, on both the Delta-88 and the keypad do not match.
If, for example, you programmed the Delta-88's fourth source button, labeled CD 1, to
control port 4 on a PCT-8 loaded with codes for the CD changer and the Delta-88's fifth
button is labeled CASS with the port 5 on the PCT-8 set to control a cassette player, yet
the keypad's fourth button is labeled CASS and the fifth button is labeled CD, you will
need to switch the two buttons around on the keypad using a small screw driver to pry
them out and then press them firmly onto the correct button.
ii
The PCT-8 may have been loaded with the correct source IR codes yet the labels
associated to these IR codes don't match the source type. Thus, even though you are
controlling track skip up functions (>> button) on the CD changer, the display on the
keypad reads "FAST FORWARD" instead of "TRACK SKIP UP". In this case you will
need to relabel (edit labels) the transport functions for that source on the PCT-8
following the instructions in the PCT-8 Installation Manual.
If an incorrect transport function label appears in the keypad's window when using a
PCT-4, the DIP switches for that source's PCT-4 port are not set to the correct position.
Use the PCT-4 Library sheet to make certain the DIP switches are set to the source you
are using. See the Appendix on the PCT-4.

PCT-8/PCT-4 Trouble-Shooting - Fine Tuning For Actual Source Control
Once you have the keypad's display reading the correct transport function names for the
sources you are controlling, you will need to test the source's actual functions. If you are not
getting transport control of the sources check the following steps.
a
When using the PCT-4, make certain the source you are using is the same make and
model number of the sources programmed into your specific PCT-4 micro processor.
The PCT-4 Code Sheet that is provided with your PCT-4 is also specific to your PCT-4
and states the exact make and model number of the source originally programmed into
the chip. Some manufacturer's sources use the same IR codes regardless of model year.
However some sources IR codes change from model year to model year.
b
Check to make sure the serial connectors or IR flashers are working.
c
Make certain that the PCT-4 or PCT-8 have their ports set to match the connectors used
(i.e. when using an IR flasher, the PCT must be set for IR Carrier). Also see the Appendix
for the PCT-4 or the PCT-8's Installation Manual. Note, some serial inputs do require
an IR carrier and some do not.
d
When using an IR carrier, you may need to adjust the PCT's carrier output level. Again,
see the Appendix for the PCT-4 or the PCT-8's Installation Manual.
e
When using a PCT-8, you can also adjust the carrier frequency output level from 30KHz
to 85KHz. You may need to adjust the carrier level although, the most typical operating
frequency is 40KHz.
