NAV/GPS Switch/Annunciator
Installations where the outputs from KLN 90B and an existing navigation system are switched be-
tween a common indicator or HSI may require some type of annunciation. A NAV/GPS switch/an-
nunciator is available that provides both the annunciation and a switch contact to energize the
switching relay(s) required for the switching of the outputs. This Switch/Annunciator is available in
5 V, 14 V, or 28 V versions as shown below.

WPT/MSG Remote Annunciators
The KLN 90B contains two outputs: 1) Waypoint Alert (WPT) and 2) Message (MSG). Annuncia-
tion of these outputs is required for certification purposes. A remote annunciator unit is available
to annunciate these outputs and is offered in either 5 V, 14 V, or 28 V versions as shown below.
The original design of this unit contained the required (WPT) and (MSG) plus two additional fields
(-/-) as it was expected that additional annunciation would be required in the future. It has now
been determined, however, that additional annunciation will not be required. Therefore, a new de-
sign is being offered that contains only the (WPT) and (MSG) fields which allows improved read-
ability. Both options are listed in the following.
