No RS-232 Data There is no RS-232 data
at the RS-232 input
port. The Air Data/Fuel Flow source is not providing RS
232 data to the GPS.
If no source of RS-232 is interfaced, the receiver
input must be jumpered back to the RS-232 out-
put on KLN 89/89Bs and KLN 90/90A/90Bs.
If no source of RS-232 is interfaced to a KLN 900,
the configuration may be set up wrong.

Predict RAIM on
OTH 3 or STA 5 This is a calculated pre-
diction of RAIM avail-
ability. The message
appears when integrity
monitoring (RAIM) is
predicted to not be
available at either the
FAF or MAP. The GPS
will not allow the unit to
go into APR ACTV
mode until conditions
improve. This is a feature, not a system failure.
Turn to the OTH 3 or STA 5 page to perform a
RAIM prediction. It will give you an indication of
how long it will be until RAIM is available.
This prediction can also be performed prior to de-
parture to insure RAIM at your arrival.
