- 8.1.1. When power lines are in the area, the radio transmission distance is reduced. The system can operate at the following distance, when the Mini Controller Unit is elevated to a maximum transmission location angle to the Remote Unit location (see Figure 81).
- 8.1.2. If the Mini Controller Unit and Remote Unit must be placed in a position other than location in Figure 81, use Figure 82 or Figure 83. The minimum transmission will occur when the Mini Controller Unit antenna and the Remote Unit antenna are placed in the line of site. The maximum transmission occurs when the line of site lays in a path of 5 to 25 degrees above unit top plane perpendicular to the antenna. Both the Mini Controller Unit antenna and the Remote Unit antenna have the same radiant energy pattern as shown in Figure 84.

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 Mini 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 Mini Controller Unit display panel. Under

no conditions should the “FIRE” switch be pressed as the Remote Unit is approached.

DO NOT bring the Mini Controller Unit closer than 100 feet (30 meters) to blasting caps,

REFERENCE SOURCE NOT FOUND. FROM MINI CONTROLLER UNIT

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

i Controller Unit

dis

excess of Error! Reference source not found., the Remote Units status transmi

may not be received by the Mini Controller Unit. The Mini Controller Unit will comma

the Remotes from a distance greater than Error! Reference source not found., but

Remote status may not be confirmed. The Mini Controller Unit performs just as it would

when it is within Error! Reference source not found. of the Remote Units. The only

difference is the method the status indications are displayed on the Min

play panel. The ARMED and DISARMED status lights for out of range Remote Units

will flash on the Mini Controller Unit display panel to indicate the Mini 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.
