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
F
U
NC
key together with the 
SCAN
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.
