4. Routeand secure the cable by attachingthe cable clamp to the transom;
drillone 9/64" diameter x 5/8"deep hole, then fill hole with marine-grade
siliconesealant, then attachthe cable clamp using a #8 x 5/8" screw.
NOTE:
If there is excess cable thatneeds to be
gathered at one location (as shown in the
illustration), dress the cable routed from both
directionsso that a single loop isleft extending from
thestorage location. Doublingthe cable up from this
point,form the cable intoa coil. Storing excess cable
usingthis method can reduce electronicinterference
(seethe illustration StoringExcess Cable).
5. Connecting the Cable
Ifyou unplugged thetransducer cableat the beginning of this procedure,plug it
backinto the depth sounder.
NOTE:The connector is keyed to prevent reverse installation, so be careful not to
forcethe plug into the connector the wrong way.
6. Testand Finish the Installation
Onceyou haveinstalled both the HDR650 and the transomtransducer,and have
routedall the cables,you must performa final test before lockingthe transducer
inplace. Testing shouldbe performed with the boat in thewater although you
caninitially confirmbasic operation withthe boat out of the water.
1. Turnon the powersource to powerup the HDR. If the unit doesnot power
up,make sure that the connectorholder is fully seated in the receptacle
andthat power is available.
2. If all connectionsare correct and power is available,the Humminbird®
controlhead will enterNormal operation.
3. If the digitaldepth readout displays on the screen,the unit is working
properly.Makesure that the boat is in watergreater than 2' but lessthan
thedepth capabilityof the unit,and that the transduceris fully submerged,
sincethe sonar signalcannot pass throughair.
