T-BOX Power Connection
T-BOX requires a 12 volt power source to operate. A connection can be made directly to a battery or a connection can be tapped into a
boat’s electrical system.
If possible, power your T-BOX using the main starting battery, not a battery that powers an electric trolling motor or other potential
source of electrical interference.
When routing the cable, be sure to stay away from, or provide cable protection around, areas with sharp metal edges. If the supplied
power cord is too short, extend it using 18 gauge wire.
IMPORTANT: Be sure to have circuit protection, such as a 1 amp fuse or circuit breaker, placed in the positive line near the power
source to protect the wiring.
Connect the T-BOX to Power
1. Be sure the power cord is not connected to the T-BOX.
2. Route the power cable from the T-BOX location to the power source.
3. Connect the red wire to the positive power source terminal and the black wire to the negative terminal.
4. Connect the power plug to the T-BOX’s power jack.
Transducer Installation
The sonar transducer style that comes with T-BOX is designed to be mounted
externally on the transom of your boat. It has a special wedged shape to allow
clear water flow when running at high boat speed. The transducer is attached
at the bottom of the boat's transom with a small portion of it extending below
the hull line.
Before you begin the process of installing the transducer, check your hull
to find a spot where you will have a smooth water flow along the bottom of
the boat. You want to avoid ribs, rivets, and gouges or scratches in the hull.
These create turbulence in the water and can scatter SonarPhone readings at
high speeds.
To get a true vertical depth reading, the transducer should be mounted parallel
to the water line. However, a 10° tilt to either side is acceptable. If the
hull is reasonably flat with a dead rise of 10° or less, mount the transducer
along the hull bottom. If dead rise is greater than 10°, mount the transducer
with level alignment.
Install the T-BOX Transducer
1. Assemble the stainless steel brackets to the transducer using the hardware furnished. Do not tighten until final adjustments
are made.
2. Place assembly on transom at selected location with the front of the transducer extending 1/2” to 5/8” below the bottom of
the boat and with the front part against the transom. The least amount that the transducer extends below the bottom is
desired. If too low, spray and turbulence will occur resulting in lost bottom readings.
