Installation 

 

LOCATION 

       Plan the location of the transceiver and microphone bracket before starting the 
installation. Select a location that is convenient for operation and does not interfere 
with  the  driver  or  passengers  in  the  vehicles.  In  automobiles,  the  transceiver  is 
usually mounted below the dash panel, with the microphone bracket beside it. 

 

MOUNTING THE RADIO 

Your  transceiver  is  supplied  with  a  universal  mounting  bracket.  When 

mounting  the  bracket  and  radio  to  your  car,  make  sure  it  is  mechanically  strong. 
Also  provide a good  electrical  connection to the chassis of  the vehicle. Proceed as 
follows to mount the transceiver: 

 

1.

 

After  you have  determined  the  most convenient location in your  vehicle,  hold 
the transceiver with mounting bracket in the exact location desired. If nothing 
will  interfere  with  mounting  it  in  the  desired  position,  remove  the  mounting 
bolts.  Before  drilling  the  holes,  make  sure  nothing  will  interfere  with  the 
installation of the mounting bolts. 

 
2.

 

Connect  the  antenna coax  connector to the standard antenna connector  on the 
rear  panel  of  the  radio.  Most  antennas  are  terminated  with  a  type  PL-259 
connector. 

 

 

3.

 

Connect the red DC power input wire (with the fuse) to +13.8V DC. This wire 
extends  from  the  rear  panel.  In  automatic  installation,  +13.8V  DC  is  usually 
obtained  from  the  accessory  contact  on  the  ignition  switch.  This  prevents  the 
set  being  left  on  accidentally  when  the  driver  leaves  the  car  and  also  permits 
operating the unit without the engine running. Locate the accessory  contact on 
most  ignition  switches  by  tracing  the  power  wire  from  the  AM  broadcast 
receiver in the car. 

 

4.

 

Connect  the  black  lead  to  –13.8V  DC.  This  is  usually  the  chassis  of  the  car. 
Any  convenient  location  with  good  electrical  contact  (remove  paint)  may  be 
used. 

 

5.

 

Mount the microphone  bracket on the right  side of the transceiver or near the 
transceiver,  using  two  screws  supplied.  When  mounting  in  an  automobile, 
place the bracket under the dash so the microphone is readily accessible.
