Caution!   Changing  the  wiring  configuration  of  the  Navigator  II  or  attempting  to  utilize  controllers  or 
wiring harnesses other than those supplied by FLIR may cause permanent damage to the unit and may 
void the warranty. 
Caution!   Do  not  connect  the  camera  to  any thing  other  than  12VDC  power.  Operating  the  camera 
outside  of  the  specified  input  voltage  range  or  the  specified  operating  temperature  range  can  cause 
permanent damage. 
Caution!  Ensure that power is turned of f at your main electrical panel before wiring the power to your 
Navigator II camera On/Of f switch,
Af ter  routing  the  camera  cables  to  the  desired  location  for  the   
display  and  the  ON/OFF  switch,  verif y  that  the  cables  will  reach 
before cutting and drilling mounting holes. 
Step  1  Using  the  “Switch  Mounting  Template”  supplied  as  a  part 
of the Installation Packet as a guide, drill holes for the switch studs 
and cut the access hole for mounting the On/Of f switch. 
Step  2  Connect  the  12VDC  power  and  return  wires  from  your   
protected  main  electrical  panel  to  the  camera  system  wiring   
harness.  Wire  must  be  16  gauge  with  a  maximum  run  of  100 
feet.  The  power  leads  are  the  red  and  black  wires  without   
terminal lugs.
Note:  Depending  on  your  switch  mounting  location  you  may  want  to  connect  the  terminal  lugs  either 
before or af ter installing the switch.
Step  3  Check  the  gasket  under  the  switch  plate  for  integrity  and  securely  fasten  the  switch  in  place 
with the two M4 flat washers, lock washers, and hex nuts provided. 
Step 4 Connect the camera harness terminal lugs to the ON/OFF switch. As shown below, there are 
five blade terminals in three horizontal rows. Only four of the terminals are used.

							disassembly and assembly of the camera Base – 
For stat Ic co NFIgUrat Io N o NlY
If  you  are  mounting  the  camera  with  wood  screws,  it  may  be  necessary  to  partially  or  completely   
remove the base from the camera in order to securely attach the base to the vessel. With the camera 
removed, there is a screwdriver access hole for each mounting screw in the base flange. Remove the 
camera from its base as described in the following steps.
Note:  Removing  the  camera  from  its  base  for  installation  may  require  that 
you  disconnect  power  wires  from  their  terminal  block  and  the  video  cable 
from its connector.
Step 1 Using a 2.5mm hex wrench, remove the six M4 socket head screws 
attaching the camera to its base (only four screws are shown in Figure 12). 
Carefully  separate  the  camera  from  its  base.  There  is  a  small  service  loop 
between the camera and the base.
Step  2  Disconnect  the  conductors  at  the  cable  side  of  the  terminal  block. 
Note the wire color code for reconnecting the wires to the terminal block.
Step 3 With the camera removed from its base, using the self-tapping screws supplied, continue with 
the installation as described above. To reassemble the camera to the base, continue with the following 
steps.
Step 4 Reconnect the four conductors and shield to the cable side of the terminal block. 
Note: To ensure a lasting seal, apply loctite 635 or equivalent to the M4 screws holding the camera to 
its base.
Step  5  Reposition  the  camera  on  its  base,  ensuring  that  the  front  window  is  facing  the   
correct direction. 
Step  6  Apply  loctite  to  the  six  M4  button  head  screws  and  using  a  2.5mm  hex  wrench,  alternately 
tighten the screws to secure the camera in place.

							NaVI gator II s PlIc E KI t – a pplies to both configurations
For  installations  requiring  the  easy  removal  and  re-installation  of  the  Navigator  II  camera  body,  the   
camera comes with a Splice Kit. The Splice Kit includes:
Installation procedure:
Step 1 Determine the place you would like to install the Splice Kit.
Step 2 Trim of f outer cable jacket exposing four insulated wires and the un-insulated signal drain.
Step 3 Strip approximately ¼” of insulation of f each wire.
Step 4 Slide Strip Seal over each wire, so that the narrow end is flush with the end of the wire’s insulation. 
 
Step 5 Crimp terminals to the wires and Strip Seal as shown.
5-way Weather Pack tower
Shroud
Weather Pack Strip Seals  (color may vary) Male and Female terminals
Crimp Here 
						

							Step 6 When finished, all 5 terminations should look like this (female termination shown). 
Note that the un-insulated signal drain is also terminated.
Step  7  Insert  the  male  terminations  in  the  grey  shrouds  and  the  female  terminations  in  the  black  
towers.  Push  them  in  until  you  hear  them  click  into  place.  (More  detailed  Weather  Pack  termination 
instructions are available on their website, http://w w w.weatherpack.com/weatherpackfaqs.html.) 
CAUTION!!!  The  shroud  and  tower  are  keyed  to  ensure  one-way  connection.  Take  care  to  make 
sure that the wires on each end match the other, or you will damage the Navigator II!
Step  8  When  you  are  sure  that  the  wires  will  mate  correctly,  snap  the  tower  and  shroud  together. 
Check for proper signal continuity before you apply power to the system. 
						

							The Splice Kit also includes Snap-N-Seal video connectors; their use is optional. 
Step 1 Slide connector assembly over cable as shown. 
Step 2 Prepare cable end. Cut the cable end of f square before starting 
the prep. 
Step  3  If  using  single  braid  cables,  fold  the  braid 
over  the  jacket.  Fold  the  inner  braid  over  the  jack-
et. 
Step  4  Twist  connector  to  remove  from  plastic 
sleeve.  (Plastic  ring  may  stay  attached  between   
connector  collar  and  nut).Place  connector  over 
cable end until cable dielectric is flush with end of 
post. Push plastic sleeve into connector.
Step 5 Finish the connector to cable installation by 
crimping with the appropriate finishing
