CAUTION
To operate the GNC 420 P/N 011-00506-00 or GNS 430 P/N 011-00280-00 COM
transceiver in a 14-volt aircraft, a 14 to 28 volt converter such as a KGS Electronics
models RB-126 or UC-14-28 or equivalent must be used. The voltage converter should
include a circuit breaker on its output to supply power to P4002-11 and P4002-12 for the
COM transmitter. The other power input pins (P4001-19, P4001-20, and P4006-44)
accept 11-33 V

on all power inputs. Refer to Figure F-13 on page F-27.
A power connection on P4006-44 is only required if NAV SUPERFLAG and/or G/S SUPERFLAG is
utilized.
The power inputs P4001-19 and P4001-20 provide power for all functions of the 400 Series unit except the
COM transmitter and the NAV & G/S SUPERFLAG outputs.
