WARNING
To use the radio, please connect the antenna to the jack "B" on the back panel of the equipment rst and then measure the SWR
(Standing Wave Ratio) before transmitting (at this subject read the chapter nr.5/ page 3). A badly tuned antenna can destroy the nal
TX amplier, these components are NOT covered under warranty.
INSTALLATION
1. WHERE AND HOW TO MOUNT YOUR RADIO
a) It is impoant to identify the proper place of the installation by considering "key criteria", such as easy access and congenial spaces
with freedom of movement.
b) The radio must not compromise the comfo of either: the driver and the passengers.
c) Remember to provide cables in harmony with safety and prevention "standards". As well as guide their wiring in protected channels
(eg: power supply, antenna, accesso wiring), so that they do not inteere in any way with the driving of vehicles.
d) To install your equipment, use the bracket (1) and the self-tapping screws [2] provided (drilling diameter 5 mm). Be careful not to
damage the vehicle's electrical system when drilling the dashboard.
e) Do not forget to inse the rubber joints [3] between the radio and its bracket as they have a cushioning eect that allows a delicate
orientation and tightening of the device.
f) Choose where to place the microphone holder and remember that the microphone cable must extend to the driver without
inteering with the vehicle's controls.
