[Premium-Rx] Cubic Communications R-2145 and R-3030

[refmon]

Hi everybody,

John Collins here...the debounce cap is in the panel interface, not the
serial interface.  Open the front and rear covers...find the potted 3.3uf
tantalum cap, and on the rear, solder a small scale 4.7 or 6.8 uf cap in
parallel.  If you look up the data on the keypad encoder chip, this cap is
actually named none other than the "debounce capacitor".

I have a tentative fix for the baggy/floppy keypad overlay that involves
injecting flexible adhesive in between the keys (not on the keys)...requires
a tiny syringe and tiny needle, available legitimately at most farm supply
stores...believe it or not, nobody even gives a question like "I need 100
3cc syringes and 22gage needles" a second thought.

Just for the record, I discovered this because we do our own veterinary
injections on our various animals.

Good luck

John Collins
