SAFETY INSTRUCTIONS

Read all warnings to avoid fire, injury or damage.
Do not attempt to use the CB radio while driving. This would put you at risk of a traffic accident.
This CB radio is designed for a 12/24 V DC power sup-ply. Do not use a higher voltage!
Do not place your CB radio on a dusty, damp or unstable surface.
Do not connect the antenna while transmitting, as this could result in burns or electric shocks.
Please stay away from equipment that could interfere with the use of the radio (e.g. televisions, generators, etc.).
Persons wearing pacemakers are advised to keep their distance from the antenna during transmission and especially not to touch it.
Do not insert any metal objects inside the CB radio. This can damage the electronics and there is also a risk of electric shock.
Avoid exposing your CB radio to temperatures lower than -26°C and higher than +60°C. The temperature in a vehicle may eventually exceed 80°C, which may cause damage to your CB radio. Do not expose the CB radio to direct sunlight for long periods of time.
Do not place anything on top of the cabinet or it will overheat.
Check that the vehicle battery is sufficiently charged.
It is important to switch off the CB radio before starting the engine to prevent damage due to high starting voltage.
When you replace the fuse, you must use a 2 A type F fuse. Never use a fuse with a higher value. t If an unusual smell or smoke is detected from the CB radio, switch off the radio immediately.
If possible, do NOT transmit for a long time, as the CB radio heats up, which can lead to errors.
