Delivery and Inspection 

 

Thank you for purchasing the DTG2 inspection and exploration system; 

the world’s only 

premium grade, 

portable, affordable and easy to use underwater ROV.  We want the time you spend with your new 
remotely operated vehicle (ROV) to be entertaining and successful so please read the entire manual 
before using this product for the first time.  
 
The DTG2 ROV is ready for use as delivered from the factory.  The unit has been fully tested and 
inspected prior to shipping, including a pressure test equivalent to the maximum dive depth.

 

 

 

Leaving the batteries fully drained for long periods of time will cause permanent damage.  We 
recommend fully charging them every 6 months to ensure they do not fully self-discharge over time. 

For more information regarding the charging, see the section in the manual entitled 

Charging.

   

 
Fully inspect your ROV to ensure it has not been damaged during shipping.  If you suspect a problem 
please contact Deep Trekker support or your authorized Deep Trekker Dealer for assistance.   
 
The DTG2 is shipped to you with the two shipping set screws in the locked position, the DTG2 will not 
operate with these screws locked.  This ensures that the rough motions associated with the delivery 
service do not damage the internal frame and the servo motor that turns it. 
 
To release the shipping set screws the following steps 
must be taken. 
 
1)

 

Rotate ROV upside down with the handles facing 
downward.  This will ensure it does not rotate 
until the screw is completely backed out.  While in 
this position, turn both set screws using a flathead 
screwdriver counter-clockwise until the set screw 
heads are firmly against the cover plate.   

*DO NOT COMPLETELY REMOVE THE SHIPPING SET 
SCREW UNDER ANY CIRCUMSTANCES.  THIS OPENS 
UP THE SEALED UNIT AND WILL LEAD TO IMMEDIATE 
FAILURE IF SUBMERGED* 

2)

 

Slowly rotate ROV to its level position.
