PERIODIC MAINTENANCE

 

 
 
   There is no maintenance for the 48710.  As long as the amplifiers are kept away from extreme 
temperatures and moisture, the amplifier should provide long-term, care-free operation. 
 
   However, as a system periodically check all RF connections for corrosion, strain damage, and tightness 
and periodically check the AC power connections for integrity.
