NOTICE:
Before you add any sound equipment to your
vehicle
--
like a tape player, CB radio, mobile
telephone or two-way radio
--
be sure you can
add what you want. If you can, it's very important
to do it properly. Added sound equipment may
interfere with the operation of your vehicle's
engine, Delco@ radio or other systems, and even
damage them. And, your vehicle's systems may
interfere with the operation of sound equipment
that has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
