Some RT Orbit Blocks™ can be set to Automatic mode or Manual mode to suit the application or user’s preference.
OPERATION
MANUAL MODE
RT blocks leave the factory in Manual mode, with the black MODE switches on both sides of the block positioned away from the red ON/OFF knob.
Use the red ON/OFF knob to turn the ratchet ON or OFF.
AUTO MODE
With the block in Manual mode, turn the ratchet off by rotating the red ON/OFF knob to the OFF position.
Slide the black MODE switch firmly toward the red ON/OFF knob until it locks into the recess in the knob. Repeat with the MODE switch on the other side of the block.
The block is now in Auto mode.
To return to Manual mode, slide the black MODE switches on both sides of the block firmly away from the red ON/OFF knob. Now use the red ON/OFF knob to turn the ratchet ON and OFF.
 | We recommend using the RF613S shackle to securely attach the block to the existing deck eye on your boat. This helps the block maintain maximum freedom of movement and reduces the risk of wear on the Dyneema loop due to sharp edges on the deck eye, then use the 8072 Rubber Boot to keep the block upright and provide a neat finish.
