REMOVAL
(1) Remove dust cover of unit as described in Paragraph 2.2.1.
(2) Remove and retain the four screws securing the crystal filter board assembly, P/N
923069-1 to the standoffs on the Frequency-Set Memory Board. Pull the crystal filter
board assembly straight up to avoid damaging the Frequency-Set Memory Board
connector pins.
REPLACEMENT
(1) Align the pins on the bottom of the crystal filter board with their sockets on the Mother
Board. Push the crystal filter board straight down until it rests on the Mother Board
standoffs.
(2) Secure the crystal filter board to the standoffs with the four mounting screws.
NOTE: Make certain that the memory set board, module A5A1 is programmed to the same
operating frequency as the crystal filter board assembly. If no crystal filter board assembly
(option) is installed, jumper board assembly P/N 923074-1 must be installed.
2.3 CHANNEL FREQUENCY SELECTION
Early radios have their frequencies programmed by a diode matrix as
described in Section 2.3.3. For radio units shipped after July 2012 and
equipped with a USB port, please refer to Appendix A (TiL TDP-90
