All personnel engaged in the handling, firing, andstorage of the system covered in this manual must fully understand these WARNINGSand CAUTIONS, and procedures by which hazardous conditions are to be reduced oreliminated. Also listed are general safety precautions that are not related to any specificprocedures and therefore don't appear elsewhere in this publication. These arerecommended precautions that personnel must understand and apply during manyphases of operation and maintenance.WARNING Never rely on the equipment for your safety.WARNING Use of this system and its components must be restricted to personnelqualified and experienced in the field of explosives and detonating devices. Under nocircumstances shall untrained personnel attempt to use this manual as a text for self-teaching.WARNING This system and its components should be stored in a secure area withno access to unauthorized personnel. This system can be used in conjunction withexplosives as a deadly weapon.WARNING These radios contain batteries. The potential for activation is alwayspresent whether or not antennas are attached to the units.WARNING Employ standard blasting system safety standards when using thisequipment with explosives.WARNING Lightning induced energy, caused by electrical storms, can detonateexplosives. In the interest of safety, blasting on land, water and underground should besuspended and all personnel should be evacuated to a safe distance from the blastarea whenever lightning storms are in the vicinity. Dangerous levels of static electricitycan build up in the atmosphere. These levels can be sufficient to detonate explosives.WARNING Radio frequency energy of sufficient magnitude can cause blastingcaps to detonate.WARNING To eliminate long wire runs, and to make the "shoot" from a safedistance, the Remote Firing Device uses low energy level radio frequencytransmissions.WARNING The Controller Unit has a 5 watt output power level (5 mile transmitrange). The Controller Unit should be considered DANGEROUS and NEVER beoperated within 100 feet (minimum) of blasting caps, wires connected to blasting caps,or other electrically initiated explosives devices. Do NOT apply power to the ControllerUnit unless the operator is at least 100 feet from blasting caps, wires connected toblasting caps, or explosives.
RFD OPERATOR MANUAL ixWARNING Do not connect a blasting cap to a Detonator Unit unless the greenSAFE light is on, the red ARMED light is off, and the yellow ON/LOW BATT light is onsteady. This indicates there is no voltage on the binding posts, the binding posts areelectically isolated from the firing capacitor, the binding posts are shunted to each other,and the battery is not low.WARNING Ensure that blasting caps are not connected to any of the DetonatorUnits during bench test.WARNING This is a sensitive electronic radio system and it may be damaged.WARNING Detonator Units have been tested and are safe to use near explosivesand blasting caps. The low level of transmit power (less than 100 milliwatts) used bythe Detonator Unit will NOT detonate blasting caps, even if they are directly connectedto the Detonator Unit's antenna terminals. The Detonator Unit transmission range islimited - approximately 1,000 feet. The Detonator Units will receive and will act uponcommands from the Controller Unit which may be located in the line of site up to 5 milesaway. The controller Unit need not and may not receive verification from a DetonatorUnit which is more than 1,000 feet away.CAUTION Do not assume the Disarm command has been received by theDetonator Unit unless DISARMED status is confirmed with a steady DISARMED lightfor that Detonator Unit on the Controller Unit display panel. If distance appears to bethe problem, move closer to the Detonator Unit following standard procedures for thistype of situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedlyas the Detonator Unit is approached. Maintain a safe distance from the Detonator Unit.Do not approach the Detonator Unit until Disarmed status is confirmed with a steadyDISARMED light for that Detonator Unit on the Controller Unit display panel. Under noconditions should the “FIRE” switch be pressed as the Detonator Unit is approached.Do not bring the Controller Unit closer than 100 feet to blasting caps, wires connected toblasting caps, or other explosives.CAUTION All units must be thouroughly tested and the batteries fully chargedprior to operational use.CAUTION Unequal air pressure inside the Controller Unit may affect theoperation of membrane switch keypad. Extreme pressure differentials may irreversiblydamage the keypad and/or cases.CAUTION Vents in all units should be momentarily opened and closedimmediately before use.CAUTION Do not open a vent if there is water on or near the vent. Takenecessary precautions to ensure water does not enter the vent.CAUTION Do not use any component that is damaged, suspected of beingdamaged, or is not able to operate as designed.
