1669-R RFD OPERATOR MANUAL REV. PP1

5.4.11. Refer to Post Operational Procedures in chapter 5.5.14.

5.5. SYSTEM OPERATION – REMOTE UNITS BOTH WITHIN AND IN EXCESS OF

1 MILE AND LESS THAN 5 MILES FROM CONTROLLER UNIT.

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

1 mile, 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.

5.5.1. The RFD will operate in a two-way mode (confirmed communications – range

to 1 mile) and one-way mode (unconfirmed communications – range greater than 5

miles).

5.5.2. If the Remotes are within 1 mile of the Controller Unit, the status of the

Remote Units (ON/LOW BATT, ARMED, and SAFE) will be displayed with solid lights

on the display panel of the Controller Unit.

5.5.3. If one or more Remote Units are out of range of the Controller Unit, the status

of these Remote Units will be assumed and their status lights will flash on the Controller

Unit display panel to indicate unconfirmed status. Accordingly the operator must

assume the following:

• Commands have been received by the Remote Units.

• The Remote Unit battery is sufficiently charged to activate the firing circuit.

• A DISARM command should not be assumed.

5.5.4. Ensure the area is clear.

5.5.5. Turn the Controller Unit on.

5.5.6. Press the “STATUS” switch. The Controller Unit will request status from all

Remote Units. The red TX light will flash for approximately 15 seconds. The green

DISARMED light on the Controller Unit display panel will flash for all the Remote Units

that the Controller Unit does not receive a status message from.

5.5.7. Select the Remote Units that are to be used in the shot by pressing the

corresponding numbered switches “1” through “8”. Press the numbered switches one at

a time.
