Interference with Vehicular Electronics
Warning!! Some vehicular electronic devices may be prone to 
malfunction due to the lack of protection from RF 
energy when your radio is transmitting.
Examples of vehicular electronic devices that may be affected by RF 
energy are:
■ electronic fuel injection systems
■ electronic anti-skid braking systems
■ electronic cruise control systems
■ indicators.
If the vehicle contains such equipment, consult the vehicle manufacturer or 
dealer to determine whether these electronic circuits will perform normally 
when the radio is transmitting.
Preparation when Drilling Holes
Warning!! When drilling holes in the vehicle, check that drilling 
at the selected points will not damage existing wiring, 
petrol tanks, fuel lines, brake pipes, or battery cables.
Vehicles Powered by Liquefied Petroleum Gas
Warning!! Radio installation in vehicles powered by LPG 
(liquefied petroleum gas) with the LPG container in a 
sealed-off space within the interior of the vehicle must 
conform to the National Fire Protection Association 
Standard NFPA 58. This standard states that the radio 
equipment installation must meet the following 
requirements:
■ The space containing the radio equipment shall be isolated by a 
seal from the space containing the LPG container and its fitting.
■ Outside filling connections shall be used for the LPG container 
and its fittings.
■ The LPG container space shall be vented to the outside of 
the vehicle.
Radio Installation in Gas or Fuel tankers
Special conditions must be observed when installing a radio on gas and fuel 
tankers. Consult your radio provider or Tait-accredited service center for 
more details.
