Chapter 7 — COMMUNICATIONS EQUIPMENT AND OPERATIONAL PROCEDURES 



which may be performed by the Aerographer's 

 Mate. These are limited to the inspections, 

 checking of switches, and cleaning described in 

 the following paragraphs. 



CHASSIS ASSEMBLY COMPONENTS. — Under 

 normal conditions, the components of all chassis 

 assemblies should be inspected for dirt, rust, 

 or corrosion on a monthly basis. If the equip- 

 ment is located under exceptionally hot, humid, 

 or dusty conditions or in the proximity of salt 

 water, these inspections should be conducted 

 weekly. 



If cleaning is required, remove grease and 

 oil from the chassis and cabinets using cleaning 

 solvent, Federal Specification P-S-661, or 

 equivalent. To clean painted panels use cleaning 

 compound Military Specification MIL-C-18687, 

 and warm, clean water. Rinse with clean water. 



CAUTION: If solvent is used be sure the 

 area is well ventilated. Do not inhale solvent 

 vapors or allow solvent to come in contact with 

 the SKin. Keep solvent away from open flame. 



TELEVISION VIEWERS. — Under normal con- 

 ditions, the glass on the front of the television 

 viewers should be cleaned weekly; if other 

 than normal conditions exist, they should be 

 cleaned daily. 



If cleaning is required, use a soft cloth 

 soaked in aliphatic naphtha, Federal Specifica- 

 tion TT-N-95A. Polish with a clean dry cloth. 



CONSOLE LIGHT TABLE. — The plastic cover 

 on the console light table should be cleaned 

 weekly unless required more often due to dusty 

 conditions. Cleaning should be accomplished by 

 washing with a soft cloth and warm, clean water 

 and then polishing with a soft dry cloth. 



The lamps in the console light table should 

 be checked daily to ensure they are operating 

 properly.

A typical weather office has two distinct and 

 relatively independent work areas (forecaster and 

 observer). The COMEDS system was designed 

 on the precept that data must be delivered and 

 messages composed in the appropriate work area.
