The TA -312 Field Phone (LEGENDARY) WE CALLED THE BATTERIES BA 30S
The analog, 2-wire, battery operated TA-312/PT replaced and will interoperate with the World War II and Korean War EE-8 field phone. The rugged and reliable TA-312 was used from the 1950s through the 1980s before being superceded by the TA-838 analog field phone. TA-312's continue in use throughout the U.S. forces as well as many allied countries.
The TA-312/PT is a two-wire, battery operated field telephone. It has a
range of 38 km using WD-1 wire, and was a successor to the EE-8 field
phone used during World War II and Korea. Primarily used from 1950-
1990, it was replaced by the TA-838. It's typically stored in a canvas
bag. An optional TA-955 dual tone multifrequency (DTMF) adapter
allows push button operational interface with automatic analog switches.
To install the TA-312 telephone:
* Strip away one-half inch of insulation from each strand of the WD-1
wire line.
* Depress the spring-loaded line binding posts and insert one strand of
the wire into each post. It doesn't matter which one goes where.
* Adjust buzzer volume control knob to LOUD.
* Turn the INT-EXT switch to INT (Internal). The TA-312 has the
capability of either using the standard H-60/PT handset (INT) or an
external H-144/U headset (EXT).
* Turn the circuit selector switch to LB. (Local battery).

* Insert the two BA-30 batteries into the battery compartment (one up
and one down). Two D-Call batteries work just as well.
* Seat the handset firmly in the retaining cradle.
* Turn the handcrank rapidly a few turns. Remove the handset from the
retaining cradle and wait for the other operator to answer.
* Depress the push-to-talk switch to talk. Release the push-to-talk
switch to listen.
The Technical Manual used for the TA-312 is TM 11-5805-201-12.

I certainly remember the TA -312 Field Phone SFC Joe S. Davis Jr., MSM, DSL from my enlisted days at Fort Campbell when I was not allowed near the phone except to run wire. Later as a cadet at West Point I was able to actually use that phone in the late 1970's and as a young LT in an Infantry Battalion I saw the TA 312 is use a few times.
