Removing the Tether 

 

In general, the tether should not be removed from the DTG2 ROV. The carrying case is designed to hold 
the DTG2, tether, and controller entirely in the one case. In the unlikely event that you do need to 
remove the tether from the DTG2, follow the following steps to ensure no damage is caused to the 
tether or DTG2: 

1.

 

Turn off ROV for service in a dry area. 
 

2.

 

Using a Phillips screw driver, remove the 4 
screws holding the black bracket to the 
rear of the ROV. 
 

 

3.

 

Using a 17mm wrench, unthread the nut 
holding the tether on black bracket.  Once 
the nut is completely unthreaded, the 
tether can be removed from the bracket. 

 

 

4.

 

Using a wrench, disengage the tether from 
the ROV body.  Place the wrench on the 
steel hex next to the ROV body.  Unthread 
the nut, while supporting the tether 
housing by hand ensuring that it does not 
rotate with the nut.  Continue to turn until 
the tether is fully disengaged.  It is 
important to fix the rotation of the tether 
using your hand or another tool.  If the 
tether is allowed to rotate while the 
stainless steel nut is rotating, the pins will 
be damaged and the ROV will need 
extensive repair.
