A WORD ABOUT  TUNING ETIQUETTE 

Be  sure  to  use  a  vacant  frequency  when  tuning.  With  today’s  crowded  ham  bands,  this  is 

often  difficult.  However,  causing  interference  to  other  hams  should  be  avoided  as  much  as 
possible.  The  AT-100ProII’s  very  short  tuning  cycle,  as  little  as  a  fraction  of  a  second,  minimizes 
the  impact  of tuning  transmissions. 

CARE AND MAINTENANCE 

The  AT-100ProII  tuner  is  essentially  maintenance-free.  Power  limits  in  this  manual  should 

be  strictly  adhered  to.  The  outer  case  may  be  cleaned  as  needed  with  a  soft  cloth  slightly 
dampened  with  household  cleaning  solution.  As  with  any  modern  electronic  device,  the  AT-
100ProII  can  be  damaged  by  temperature  extremes,  water,  impact,  or  static  discharge.  LDG 
strongly  recommends  the  use  of  a  good  quality,  properly  installed  lightning  arrestor  in  the 
antenna  lead.

TWO-YEAR  TRANSFERRABLE  WARRANTY 

Your  product  is  warranted  against  manufacturer  defects  in  parts  and  labor  for  two  full  years 

from  the  date  of  purchase.  This  two-year  warranty  is  also  transferable.  When  you  sell  or  give 
away  your  LDG  product,  give  the  new  owner  a  copy  of  the  original  sales  receipt  and  the  two-
year  warranty  goes  with  the  new owner. 

There  is  no  need  to  complete  a  warranty  card  or  to  register  an  LDG  product.  Your  product 

receipt  establishes  eligibility  for  warranty  service,  so  save  that  receipt.  Send  your  receipt  with  the 
product  whenever  you  send  your  product  to  LDG  for  repair.  Products  sent  to  LDG  without  a 
receipt  are considered  requests  for  out-of-warranty  repair. 

LDG  does  not  warranty  against  product  damage  or  abuse.  This  means  that  a  product  failure, 

as  determined  by  LDG,  to  be  caused  by  the  customer  or  by  other  natural  calamity  (e.g.  lightning) 
is  not  covered  under  the  two-year  warranty.  Damage  can  be  caused  by  failure  to  heed  the 
product’s  published  limitations  and specifications  or by not following  good Amateur  practice.
