    3. INITIAL INSTALLATION 3.1 Mobile Installation To  install  the  transceiver,  select  a  safe,  convenient  location  inside  your vehicle that minimizes danger to your passengers and yourself  while  the  vehicle  is  in  motion.  Consider  installing  the  unit  at  an  appropriate  position  so  that  knees  or  legs  will  not  strike  it  during  sudden braking of your vehicle. Try to pick a well ventilated location ...

  • Page 9: Power Connection

    3.2 Intall Microphone Hanger 1. Choose idea location and mark for screw point. 2. Fix the hanger by the srews in accessory list. 3.3 Power Connection » Locate the power input connector as close to the transceiver as possible. Mobile Operation The vehicle battery must have a nominal rating of 12V. Never connect  the transceiver to a 24V battery. Be sure to use a 12V vehicle battery  that  has  sufficient  current  capacity.  If  the  current  to  the  transceiver  is  insufficient,  the  display  may  darken  during  transmission,  or  transmitting output power may drop excessively.
  • Page 10 In  order  to  avoid  the  risk  of  short  circuit,  please  cut  down  connection with negative (-) of battery, then connect with radio. Confirm  the  correct  polarity  of  the  connections,  then  attach  the  power  cable  to  the  battery  terminals;  red  connects  to  the  positive  (+)  terminal  and  black  connects  to  the  negative  (-)  terminal.
  • Page 11 Fixed Station Operation In  order  to  use  this  transceiver  for  fixed  station  operation,  you  will  need  a  separate  13.8V  DC  power  supply  (not  included),  Please contact local dealer to require. The recommended current capacity of your power supply is 10A. Connect the DC power cable              and ensure that the polarities are correct. (Red: positive, Black:  negative). •  Do not directly connect the transceiver to an AC outlet. • ...

  • Page 13: Antenna Connection

    3.5 Antenna Connection Before operating, install an efficient, well-tuned antenna. The success  of your installation will depend largely on the type of antenna and its  correct  installation. The  transceiver  can  give  excellent  results  if the  antenna system and its installation are given careful attention. Use  a  50Ω  impedance  antenna  and  low-loss  coaxial  feed-line  that  has  a  characteristic  impedance  of  50Ω,  to  match  the  transceiver  input impedance. Coupling the antenna to the transceiver via feed- lines having an impedance other than 50Ω reduces the efficiency of  the antenna system and can cause interference to nearby broadcast  television receivers, radio receivers, and other electronic equipment.  » Transmitting without first connecting an antenna or other matched load may damage the transceiver.
