How to Use Audio and Visual Systems
„
SETTING AUDIO/RADIO
• If the battery is disconnected for servicing or replacement of the battery or a fuse, all the
settings for stored channels and the speakers will be erased.
•
Reception of radio and broadcasts depends on your location because the radio signal
strength varies. Also, it may be difficult to maintain constant signal reception due to the effect
of obstructions.
•
Images can be distorted or noise may be generated by interference from nearby overhead
power lines on railroads, high-tension leads, traffic lights, neon signs, or aerials
transmitting radio or amateur radio broadcasts.
•
Due to the characteristics of radio waves, signal reception may be adversely affected by
obstructions such as buildings and mountains.
•
When you enter a tunnel or move away from a broadcasting station, the signal strength
will become extremely weak and the conditions for signal reception will be degraded.
•
In some areas, video and audio reception can be adversely affected by nearby aerials
transmitting radio broadcasts at frequencies different from the one actually being
received.
•
The range of reception this navigation device is capable of is narrower than that of home
devices.
• Reception can be adversely affected by the operation of your vehicle’s windscreen wipers,
electric mirrors, and air conditioner system.
