from actual and displayed rudder angles.

1. With the rudder centered, press the 

W

 and 

X

 keys together until the 

instrument starts beeping continuously. The beeping indicates you 
have correctly enabled the calibration mode.

2. Use the 

W

 and 

X

 keys to move the pointer to the zero position.

3. Press the 

W

 and 

X

 keys together again to save the setting and 

escape from the calibration mode.

The terminal resistor enables/disables connection of the FI-506 to an 
NMEA 2000 network, and it is disabled at the factory. To turn the resistor 
on or off, press and hold down the BRILL and

keys together until you 

hear a beep. Then, press the 

X

 key to turn the resistor on or off. The 

number of beeps indicates ON or OFF. Two beeps for ON, three beeps 
for OFF. Press the BRILL and 

W 

keys together to save the setting and 

return to normal operation. A beep sounds upon completion.

The data shared within the FI-50 instruments series can be synchro-
nized, so that all data agrees. You can turn synchronization of all data on 
or off, or synchronize data by group, A and/or B. For group synchroniza-
tion, instruments having like group synchronization settings are synchro-
nized.

To set synchronization, press and hold down the BRILL and

gether until you hear a beep. Then, press the 

X

 key to select applicable 

synchronization setting. The number of beeps and beep duration indi-
cate the setting as shown below. Press the BRILL and
