1669-R RFD OPERATOR MANUAL REV. PP1

WARNING Ensure that blasting caps are not connected to any of the Remote

Units during bench test.

WARNING This is a sensitive electronic radio system and it may be damaged.

WARNING Do not use the Controller Unit within 100 feet of explosives, blasting

caps, or wires leading to them. The controller signal is 5 watts, which can cause

detonation of caps if within 100'. The 5 watt 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 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 igniter tip jacks on the Radio 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 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 Controller Unit display panel. Under no

conditions should the “FIRE” switch be pressed as the Remote Unit is approached. DO

NOT bring the Controller Unit closer than 100 feet 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 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. Take

necessary precautions to ensure water does not enter the vent.

CAUTION Do not use any component that is damaged, suspected of being

damaged, or is not able to operate as designed. The safety of the operation could be

compromised.
