[Collins] Manual of SPECTRUM-2000

[Katsuhiko Hirai]

Hi!
I'm looking for the manual of RS-2101, receiver-exciter,  for Collins
SPECTRUM-2000.
Does anyone have it?

PS) My previous asking at 20 May, 2020 was my wrong typing as "RS-2401", 
instead of "RS-2101", then I apologize for making confusion.

I appreciated your information, 73
Best regards,
Katsuhiko Hirai/ JA3ECA
