1669-R RFD OPERATOR MANUAL REV. PP1 

viii

The following are WARNINGS and CAUTIONS, contained throughout this manual and 
are repeated here for emphasis.  All personnel engaged in the handling, firing, and 
storage of the system covered in this manual must fully understand these WARNINGS 
and CAUTIONS, and procedures by which hazardous conditions are to be reduced or 
eliminated.  Also listed are general safety precautions that are not related to any specific 
procedures and therefore don't appear elsewhere in this publication.  These are 
recommended precautions that personnel must understand and apply during many 
phases of operation and maintenance. 

Never rely on the equipment for your safety. 

Use of this system and its components must be restricted to personnel 

qualified and experienced in the field of explosives and detonating devices. Under no 
circumstances shall untrained personnel attempt to use this manual as a text for self-
teaching. 

This system and its components should be stored in a secure area with 

no access to unauthorized personnel.  This system can be used in conjunction with 
explosives as a deadly weapon. 

These radios contain batteries.  The potential for activation is always 

present whether or not antennas are attached to the units.  

Employ standard blasting system safety standards when using this 

equipment with explosives. 

Lightning induced energy, caused by electrical storms, can detonate 

explosives.  In the interest of safety, blasting on land, water and underground should be 
suspended and all personnel should be evacuated to a safe distance from the blast 
area whenever lightning storms are in the vicinity.  Dangerous levels of static electricity 
can build up in the atmosphere.  These levels can be sufficient to detonate explosives. 

Radio frequency energy of sufficient magnitude can cause blasting 

caps to detonate. 

To eliminate long wire runs, and to make the "shoot" from a safe 

distance, the Remote Firing Device uses low energy level radio frequency 
transmissions.  

Do not connect a blasting cap to a Remote Unit unless the green 

SAFE light is on, the red ARMED light is off, and the yellow ON/LOW BATT light is on 
steady.  This indicates there is no voltage on the binding posts, the binding posts are 
electically isolated from the firing capacitor, the binding posts are shunted to each other, 
and the battery is not low.
