BASE  STATION  INSTALLATION  AND  CHECKOUT

Unpack  the  transceiver  carefully  and  check  for  exterior  damages  and  the 

accessories.

Connect  the  3  wire  AC  cord  to  an  AC  plug  in  the  foiiowing  manner:

1.  biue  to  AC  terminal

2.  brown  to  AC  terminal

3.  yellow/green  to  the  earth  terminal

Connect  the  antenna  plug  to  the  antenna  jack  with  an  SWR-Meter  inserted  into 

the  antenna  cable.

Connect  the  microphone  to  the  microphone  jack.

Place  the  transceiver  in  operating  position  and  connect  the  AC  plug  to  a  220 

Volt  50  Hz  AC  outlet.

Check  very  carefully  that  nothing  touches  the  back  panel  and  that  there  is  a  min. 

10  cm  space  between  the  backpanel  and  any  object  nearby  because  the  transmitting 

transistors  w ill  heat  up  to  100  degree  Centigrade  and  carry  a  voltage  of  14  Voit 

DC  and  high  power  RF.

Switch  the  transceiver  ON.

The  receiving,  meter  and  the  channel  lamp  shall  light  up.

Turn  the  Squelch  control  to  min.  (ANL  OFF)

Turn  the  Volume  control  to  max.  until  you  hear  a  rushing  sound  from  the  speaker. 

Switch  the  channelselector  to  CH  1.

Push  the  transm it  button  on  the  microphone  and  check  with  the  SWR-Meter 

immediately  the  SWR  of  your  antenna.  The  SWR  must  be  less  than  1  to  2.  Do 

this  within  3  seconds,  because  if   the  SWR  is  higher  than  1  to  2  it  is  very  iikely 

that  the  transm itting  transistors  w ill  be  demaged  if  you  operate  the  transmitter 

too  long  with  a  antenna  having  a  too  high  SWR.  Also  read  carefully  the 

recommendations  on  antennas.

If  the  SWR  is  less  than  1  to  2  continue  installation. 

If  it  is  more  than  1  to  2 

repair  or  replace  your  antenna.

Check  that  the  meter  needle  is  near  the  red  mark  during  transmitting.

Talk  into  the  microphone.  The  meter  needle  shall  move  a  little .

Release  the  transm it  button  and  switch  the  channel  selector  to  channel  1,2  ectr, 

until  you  receive  a  station.

Wait  until  this  station  stops  to  transmit  and  turn  the  Squelch  control  slowiy  to 

max.  until  the  background  noise  just  disappears.  When  the  station  Starts  to 

transm it  again,  you  w ill  hear  this  station,  but  you  w ill  not  hear  the  background 

noise  during  non  transm itting  periods.
