cedure until the left-hand edge is in phase. 

 To stop the recorder manually, press the STOP 

 button on the recorder front panel. To manually 

 fast feed the paper, press the FAST FEED switch 

 until the desired amount of paper is fed out, 

 then release the switch. 



5. NO PAPER INDICATOR. An indicator lamp 

 on the recorder cover lights whenever the paper 

 supply is depleted or the recorder cover is 

 open and the interlock switch is opened. The 

 set will stop automatically when either of these 

 occur. Either the door must be closed or a 

 new roll of paper installed before the set can 

 be started again. 



AN/UXH-2( ) FACSIMILE 

 RECORDER 



The AN/UXH-2( ) (fig. 7-9) is used aboard 

 ship and at overseas stations, in conjunction with 

 a radio receiver and a frequency shift converter, 

 for the reception of facsimile weather charts. 



The radio receiver's audio output is connected 

 to a converter which changes the signal to elec- 

 trical impulses. When patched to the latest model, 

 the AN/UXH-2B, these electrical impulses cause 

 a recording across a continuous page of paper 

 by a pressure sensitive technique. This modified 

 method utilizes a conventional helical drum in 

 combination with styluses driven by a heavy, 

 rigid, grooved rubber belt which is both stable 

 and trouble free during its long life. The three 

 styluses press the image on the back of one- 

 time carbon paper. This carbon paper and the 

 plain white paper (rolls of 350 feet each), on 

 which the image finally appears, are fed from 

 separate supply spindles. The paper supply sys- 

 tem avoids the slippage and binding common 

 with integrated paper and carbon paper feed 

 techniques during longer periods of unattended 

 operation. 



The styluses are spaced on the band so 

 only one stylus is touching the paper at a
