Initial Installation
 REPLACING FUSES
If  the  fuse  blows, determine  the  cause,  then  correct  the  problem. 
After the problem is resolved, replace the fuse. If newly installed fuses 
continue to blow, disconnect the power cable and contact your autho-
rized 
 dealer or an authorized   servi-
cecenter for assistance. 
Only  use  fuses  of  the  specified type  and  rating,  otherwise  the 
transceiver could be damaged.
After connecting the transceiver to the power supply, the supply voltage 
can be displayed on LCD by pressing the
FUN
key together with the 
key. 
The display immediately changes as the voltage supply changes, It also 
displays voltage during transmission.
The transceiver will return to its normal operation  when the power is 
switched ON or repeat above operation.
Before operating, install an efcient, 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.

If  you  use  the  transceiver  for  a  long  period when  the  vehicle  battery  is 
not  fully  charged,  or  when  the  engine is  OFF,  the  battery  may  become 
discharged, and will not have sufcient reserves to start the vehicle. Avoid 
using the transceiver in these conditions.
The  range of  displayed  voltage  is  only  from  7V  to16V  DC, because  the 
displayed value is estimated, please use a voltmeter when a more precise 
reading is desired.

Antenna Connection
Important
Transmitting  without  first  connecting  an  antenna  or  other  matched 
load may damage the transceiver. Always connect the antenna to  the 
transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to reduce 
the risk of re, electric shock, and transceiver damage.
