Installation

1.  Locate and appropriate AC outlet near the 

Dual-Wire Dual Operator Monitor, and test it for 

proper wiring and grounding prior to use. The Desco 

AC Outlet Analyzer or similar test equipment may 

be used to verify the outlet’s functionality. 

2.  Determine the mounting locations of the operator 

remotes. Be sure to install the remotes at a distance 

that enables the 10 foot leads to reach the back of 

the monitor. 

3.  Install tinned wire ends of the mat (must be 

grounded seperately) cords to their appropriate 

screw terminal block located at the back of the 

monitor. 

4.  Install the tinned wire end of the green and yellow 

moniitor ground cord to the ground terminal located 

at the back of the monitor. Install its ring terminal 

to an appropriate ground point. Be sure to use a 

different ground point than the one used for the 

mats. The face plate screw of a grounded AC wall 

outlet may provide a convenient connection point. 

5.  Route the mat cords from the back of the monitor to 

the snaps on the worksurface mats. 

6.  Insert the operator remote cables into their 

appropriate jacks located at the back of the monitor. 

The white cable is for operator #1. The black cable 

is for operator #2. 

7.  Connect the power adapter to the power jack 

located at the back of the monitor. Plug the power 

adapter into a proper AC power outlet. The monitor 

is now powered.

Operation

1.  Monitoring of the operators will remain in the 

STANDBY condition until a wrist cord is plugged 

into the operator remote. STANDBY mode is 

indicated by a blinking yellow operator LED. 

2.  Plug a wrist strap cord, not attached to the 

wristband, into the monitored jack labeled WRIST 

STRAP MONITOR located on the remote. This 

automatically activates the selected operator 

channel. The corresponding operator LED should 

illuminate red and the alarm should sound on the 

monitor. 

3.  Remove the charges from your body by making 

contact with a properly grounded ESD worksurface. 

4.  Snap the cord to the wristband, and fit it snugly 

onto your wrist. This should silence the audible 

alarm and cause the corresponding operator LED 

to switch from red to green. If this does not happen, 

examine the wrist cord for continuity or damage and 

your wrist band to ensure that it is securely fit. If you 

have dry skin, apply an approved dissipative hand 

lotion such as 

Menda Reztore® ESD Hand Lotion

5.  The AUX GND jack located on the operator remote 

is a grounded and unmonitored connection for 

guests, or other equipment grounds. It must be used 

with a single-wire Banana plug style cord.

10mm snap needs to pierce 

and clinch bottom side of 

mat. Snap needs to be at 

least 12" apart or 72" max.
