SAFETY INFORMATION
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.
WARNING Never rely on the equipment for your safety.
WARNING 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 selfteaching.
WARNING 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.
WARNING These radios contain batteries. The potential for activation is always
present whether or not antennas are attached to the units.
WARNING Employ standard blasting system safety standards when using this
equipment with explosives.
WARNING 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.
WARNING Radio frequency energy of sufficient magnitude can cause blasting
caps to detonate.
WARNING 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.
WARNING 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.
1678 RFD OPERATION MANUAL {DRAFT}

WARNING Ensure that blasting caps are not connected to any of the Remote
Units during bench testing.
WARNING This is a sensitive electronic radio system and it may be damaged.
WARNING Do not use the Mini Controller Unit within 100 feet (30 meters) of
explosives, blasting caps, or wires leading to them. The Mini Controller signal is 5 watts,
which can cause detonation of caps if within 100 feet. The 5 watt Mini Controller
complies with the Recommended Table of Distances established by the Institute for the
Makers of Explosives (IME) when placed beyond 100 feet of explosives.
WARNING Do not engage in RFD communications with the Remote Units when
they are connected to explosive charges until the shot is prepared and all personnel are
clear. The Remote Unit complies with the Recommended Table of Distances
established by the Institute for the Makers of Explosives (IME) when placed 25 feet (8
meters) or more from blasting caps or wires leading to them. For further information,
refer to the Institute for the Makers of Explosives Publication no. 20, Part II, Section (1).
WARNING Do not touch the Shock Tube Tip Jacks on the side of the Remote
Shock Tube Initiator (RSTI) when armed or firing. Lethal voltages may be present.
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,
wires connected to blasting caps, or other explosives.
CAUTION All units must be thoroughly tested and the batteries fully charged prior
to operational use.
CAUTION Unequal air pressure inside the Mini Controller Unit may affect the
operation of membrane switch keypad. Extreme pressure differentials may irreversibly
damage the keypad and/or cases.
CAUTION Vents in all units should be momentarily opened and closed
immediately before use.
CAUTION Do not open a vent if there is water on or near the vent. Keep the vents
closed when the relative humidity is above 90%. Take necessary precautions to ensure
moisture does not enter the unit case.

2.5.2. Power ON Self Test: Immediately after the Electric Remote is turned on by
installing the Antenna, a rigorous self-test is performed. If a failure is detected, the red
ARMED light will blink continuously and all other lights will be extinguished. It is not
possible to use the unit once an error has been detected. The unit must be returned to
the Manufacturer for service. Do not attempt to use a failing unit.

separation countdown timer is initiated. During the safe separation time, the SAFE and
ARMED lights will be on steady, while the ON light blinks rapidly. During the safe
separation time, the unit will not accept any radio commands (i.e. Status, Arm, Disarm,
or Fire). This is to provide a short but highly safe window of time for the user to exit the
immediate vicinity of the blast area. After the safe separation time is complete, the unit
may still be considered safe as long as it does not receive an Arm or a Fire radio
command from the system’s mated Mini Controller. Thus, it is recommended that the
mated Mini Controller be rendered unusable while personnel are within the hazard area.
This can be accomplished by the removal of the Mini Controller’s antenna and its
secure storage until ready for use. The default Safe Separation Time is 15 seconds.
Safe Separation Time: Upon the installation of the Antenna, a safe

the battery’s run time during periods of inactivity. To enter sleep mode, the unit must be
disarmed (safe and capacitor discharged) and the battery must not be low.
Approximately one minute after activity (power on or a radio command), the unit will
enter sleep mode. In sleep mode, the display lights extinguish and all non-essential
functions are suspended. Sleep mode can be exited by sending the unit a radio
command from its mated Mini Controller. Upon receipt of a radio command, the unit will
be immediately awakened and ready for operation. While in sleep mode, units may run
for 200+ hours. Actual sleep mode run time is affected by a variety of factors such as
the sleep mode setting of your system, the state of charge of the battery, the health of
the battery, and the ambient temperatures the unit will be exposed to.
