Control Box Assembly. The control box assembly contains the 

processor module with its associated electronic components and the battery pack. The 
control box housing is an aluminum water-tight enclosure. A gasketed steel cover 

secured by four latches seals the control box. The control box mounts the 

switch, 

the cable to the search head, and the headset assembly. A test connector is provided 
for test purposes. A hook on the 

box enables it to be attached to the belt and 

thus relieve strain on the operator's arms when operating in the prone position. 

Note: The shorting plug must be plugged into the test connector at all times, as removal 

disconnects the battery power from the system. 

(a) Processor Module. The processor converts the output of the 

search head to an audio signal so that it may be heard in the headset. 

(4) 

Headset Assembly. The headset provides an audible indication of 

the signals produced in the search head and then processed in the control box. The 

headset assembly consists of two earphones, joined by an adjustable stainless steel 
headband, and a headset cable. Rubber ear cushions are fastened over the two 

earphones to cut out extraneous noise and make the headset comfortable to wear. A 
clip is provided 

so 

that a pull on the headset cable will not place a strain on the 

operator's head. 

c. 

Case Assembly. The carrying case assembly is used to store the 

mine detector, its battery packs, and the carrying strap. The case is waterproof and is 

fitted with inserts with cutouts into which the various components 

of 

the mine detecting 

set are stored when not in use. An air valve is located near the latch to the right of the 

handle of the carrying case. Opening the valve equalizes the air pressure within the 

carrying case with the air pressure outside the carrying case while the equipment is 
being transported by air. 

d. Battery. Five replaceable C-size alkaline batteries in a removable holder, 

providing plus 7.5 Volts (nominal), are normally used to operate the equipment. 
(Optionally, a rechargeable lead-acid battery or a 

lithium battery with a 

connector adapter can be used in place of the alkaline battery pack.)
