5.3.6. To fire the Remote Units, press the “FIRE” switch. The operator should get

an indication of shot initiation. The ARMED light will go out and the green DISARMED

light for each selected Remote Unit will come on solid on the Controller Unit display

panel.

5.3.7. If not all the Remote Units were selected for the shot, repeat above steps to

initiate the remaining shots.

5.3.8. To disarm any Remote Units that have been armed, select the Remote Units

and press the “DISARM” switch. All selected Remote Units will return to the

DISARMED mode in approximately 3 seconds.

CAUTION Do not assume the Disarm command has been received by the Remote

Unit unless DISARMED status is confirmed with a steady DISARMED light for that

Remote Unit on the Controller Unit display panel. If distance appears to be the

problem, move closer to the Remote Unit following standard procedures for this type of

situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedly as the

Remote Unit is approached. Maintain a safe distance from the Remote Unit. Do not

approach the Remote Unit until DISARMED status is confirmed with a steady

DISARMED light for that Remote Unit on the Controller Unit display panel. Under no

conditions should the “FIRE” switch be pressed as the Remote Unit is approached. DO

NOT bring the Controller Unit closer than 100 feet to blasting caps, wires connected to

blasting caps, or other explosives.

5.3.9. Turn off the Controller Unit.

5.3.10. Recover the fielded Remote Units.

5.3.11. Refer to Post Operational Procedures in chapter 5.5.14.

5.4. SYSTEM OPERATION – REMOTE UNITS MORE THAN 1 MILE FROM

CONTROLLER UNIT.

Note: If the distance between the Controller Unit and the Remote Units is in excess of

5 miles, the Remote Units status transmissions may not be received by the Controller

Unit. The Controller Unit will command the Remotes from a distance greater than 5

miles, but the Remote status may not be confirmed. The Controller Unit performs just

as it would when it is within 1 mile of the Remote Units. The only difference is the

method the status indications are displayed on the Controller Unit display panel. The

ARMED and DISARMED status lights for out of range Remote Units will flash on the

Controller Unit display panel to indicate the Controller Unit did not receive a status

message from the Remote Unit. Once the Remote Units are set up for the shot, the

operator must assume the Remote Units have received the command.

5.4.1. Ensure the area is clear.

5.4.2. Turn the Controller Unit on.
