Note !
If you let go of key before conformation of reversed deflection has
been given, the RI35 Mk2 will think you meant to do a zero adjust and
leave the pointer at zero. Then simply repeat section 3.6.

MAINTENANCE
Simrad rudder angle indicator equipment will need no special
maintenance. It is, however, essential that the mechanical linkage
Rudder stock - Rudder Feedback Unit is regularly checked and
maintained in good condition to avoid misalignment.
5.
TEST MODE
In the incident of an error, the RI35 Mk2 has a built in self-test mode
for easier trouble finding. Holding down the illumination key during
power-up accesses the automatic self-test. A short beep after the long
start-up beep indicates that you have entered self-test mode
successfully.
The self-test will now run the pointer to 45 deg port and 45 deg
starboard, then 20 deg port, 20 deg starboard.
In 1-second intervals the self-test will set all 3-illumination levels.
When self-test is finished the RI35 Mk2 will run pointer to 0 deg and
stay there until power is recycled.
During self-test operation the NMEA port first transmits the message
(PRTNV), and then after 200 mS the message (PRTNR) as per below.
Each of the messages will be sent every 400 mS.
Note !
With no signal input the pointer moves out of scale to port (after 5
seconds).
