SERVICING  YOUR  TRANSCEIVER

The  technical  information,  diagrams  and  charts  will  be  supplied  upon  request.  It  is 
the  user's  responsibility  to  see  that  this  radio  is  operating  at  all  times in accordance 
with  the  F.C.C.  Citizens  Radio  Service  régulations.  We  highly  recommend  that  you 
consult  a  qualified  radiotéléphone  technician  for  the  servicing  and  alignment of this 
CB radio product.

Please  refer  to  the  W A R N IN G   information  contained in the  1 st page of this Owner's 
Manual.

(N OTE:  When  ordering  parts,  it  is essential  to specify the correct model  number and 

serial  number of the unit.)

MAINTENANCE  AND  ADJUSTMENT

This  transceiver  is  especially  designed  for  the  environment  encouuntered  in  mobile 
installations.  The  use  of  all  solid  state  circuitry  and  its  light  weight  resuit  in  high 
reliability.  Should  failure  occur,  however,  replace  parts only with  identical  parts.  Do 
not substitute.

At six to twelve month  intervals, the following system checks should  be made:

1.  Check Standing Wave  Ratio (SWR).

2.  Inspect ail electrical connections to ensure that they are tight.

3.  Inspect antenna coaxial  cable for wear or breaks on shielding.

4.  Inspect ail screws and other mounting hardware for tightness.

This  transceiver  is  factory  aligned  and  should  not require any adjustment when used 
with  a  52  ohm  antenna.  If  an  antenna  other  than  52  ohm  impédance  is  used, 
adjustment  of  the  transmitter  output circuit may be made to obtain optimum power 
transfer  to  the  antenna.  This  adjustment should  be  made  only  by  a  licensed  techni­
cian  using a high  quality in-line  R F  Wattmeter which will  not produce standing waves 
when  inserted  in the antenna cable.
