Section II. DESCRIPTION AND DATA

1-4. Purpose and Use

(fig. 1-1)

a. Indicator, Channel Alignment ID-1189/PR is a self-contained, case-inclosed portable, and transistorized test

equipment. It is used for aligning Transmitting Set, Radio AN/PRT-4 and Receiving Set, Radio AN/PRR-9 when channel

crystals are changed or whenever misalignment is indicated. It is also used to test Batteries BA-399/U and BA-505/U.

The ID-1189 (XE-2)/PR only, in addition, is used to align Receiving Set, Radio AN/PRR-9(XE-9) and to test Battery, Dry

BA-4534/U.

b. All tools and the test antenna, required to perform alignment procedures, are within the ID-1189/PR case cover.

Instruction plates, covering alignment and battery testing procedures, are also within the case cover. Power is obtained

from a Battery BA-399/U (not supplied). The internal battery, for early models of the ID-1189/PR only, is mounted in a

battery compartment and is accessible through a cover plate mounted or the ID-1189/PR control panel. Battery BA-

339/U is. also used to power the ID-1189 (XE-2)/PR, and is connected to an external connector located on the control

panel of the ID-1189(XE-2)/PR and later models of the ID-1189/PR.
