Telephones EE-8, EE-8A and EE-8-B

"1. General.

a. Characteristics. Telephone EE-8-(*) is a portable field telephone designed for use on either local or common battery telephone systems. It is compact, rugged, and portable, and in performance equals the best present day commercial telephones. It contains all the elements necessary for a combination local battery and common battery telephone, and the circuit elements are arranged for antisidetone transmission. The talking and signaling range of the telephone varies with the type of line wire use, the condition of the wire, whether the wire is dry or wet, and whether the wire is on the ground or in the air. The telephone will operate satisfactorily over the distances usually found in corps and subordinate wire systems, provided the lines are well constructed. When telephone EE-8-(*) is used as a local battery telephone, talking range of 11 to 17 miles may be expected on Wire-110-B, depending on weather conditions and the type of construction of the wire line. These distances may be increased by the proper use of loading coils. Capabilities of telephone when applied to different systems are discussed in paragraphs 5, 6, and 7.

b. Nomenclature. Telephones EE-8, EE-8-A, and EE-8-B are referred to in this Technical Manual as Telephones EE-8-(8). Such nomenclature refers any one or all of the above three models."
