Operation

1.  Fit the wristband snugly onto the wrist. 
2.  Snap the wrist cord to the wristband. 
3.  Plug the wrist cord into the dual-wire jack on 

the operator remote. The green operator LED 

will illuminate. This indicates that the operator is 

properly grounded. 

4.  If this does not happen, examine the wrist cord for 

continuity or damage and the wristband to ensure 

that it fits securely. If you have dry skin, apply an 

approved dissipative hand lotion such as 

Menda 

Reztore® ESD Hand Lotion

5.  The AUX MAT jack located on the operator remote 

is a grounded and unmonitored connection for 

guests or supervisors. It is intended to be used with 

a single-wire wrist strap.
