1-7. Description of Indicator, Channel Alignment ID-1189/PR

The ID-1189/PR is inclosed in a ruggedized type constructed case. The case when closed is watertight and airtight and

contains a breather valve which can be manually operated to equalize pressure between the inside and outside of the

case. A screwdriver, an alignment tool, an antenna, and instruction plates are secured to the inside cover of the case.

Two additional adapters are included inside the cover of ID-1189(XE-2)/PR case only. The ID-1189/PR circuits are

contained within the body of the case and attached to and covered by a plate assembly. The top of the plate assembly is

a control panel which contains the operating controls, jacks, and a meter. Units, such as battery type BA-399/U or BA-

505/U, Receiving Set, Radio AN/PRR-9, or Transmitting Set, Radio AN/PRT4, when being tested or aligned, are plugged

directly into the appropriate jack on the control panel. For the ID-1189 (XE-2)/PR only, the adapters are used between

the appropriate control panel jack and the AN/PRR-9(XE-9) or BA-4534/U. The control panel meter indicates the results

of tests or alignment. The meter face is worked on one scale to indicate relative center readings for alignment, and also

contains a GOOD and BAD scale to indicate a battery condition. On the ID-1189(XE-2)/PR only, the meter glass

contains an additional indicating scale that is used when testing the BA-4534/U.

capacitors, coils, and resistors adjusted during alignment of a receiver or transmitter.

c. The antenna is a 17-inch long whip antenna with a phone tip at one end and a ball at the other. It is used during

portions of the alignment procedures of a receiver or transmitter.

d. Instruction plates, laminated cards in plastic, are contained within the cover of Case, Indicator CY-6078/PR. Two

plates are provided; one contains detailed battery test and alignment information for the AN/PRT-4 and the other

contains alignment information for the AN/PRR-9. A third plate, supplied with the ID-1189(XE-2)/PR only, contains

alignment information for the AN/PRR-9(XE-9) and battery test information for the BA-4534/U. The plates are held to the

case lid by a nylon cord.

e. Adapter, Connector U-389(XE-1)/PR (battery adapter) contains a connector at the bottom end designed to fit the

RCVR BAT. connector on the top plate assembly of the ID-1189(XE-2)/PR. The top of the adapter contains a two-

conductor plug which fits the connector of Battery, Dry, BA-4534/U. When not in use, the adapter is stored in the lid of

the ID-1 189 (XE-2) /PR.

f. Adapter, Receiving Set MX-8512(XE-1)/PR (RECEIVER ALIGNMENT adapter) is used for aligning Receiving Set,

Radio AN/ PRR-9(XE-9). In use, it is installed over the RECEIVER ALIGNMENT receptacle of the ID-1189(XE-2)/PR.

The adapter contains necessary electrical connectors and receptacles for connection to the ID-1189 (XE-2) /PR circuitry.

When not in use, the adapter is stored in the case lid.
