Motorola cp185 Quick Reference Manual page 36

A repair constitutes something done internally to the unit that would
bring it back to its original condition.
Items not considered as repairs are those in which an action is
performed on a unit which does not require the outer casing of the
unit to be opened in a manner that exposes the internal electrical
circuits of the unit.
Do Not Substitute Options or Accessories
The Motorola communications equipment certified as intrinsically
safe by the approving agency, (FM, UL, CSA, CENELEC) is tested
as a complete system which consists of the listed agency Approved
portable, Approved battery, and Approved accessories or options, or
both. This Approved portable and battery combination must be
strictly observed. There must be no substitution of items, even if the
substitute has been previously Approved with a different Motorola
communications equipment unit. Approved configurations are listed
by the Approving Agency (FM, UL, CSA, CENELEC).
The Intrinsically Safe Approval Label affixed to radio refers to the
intrinsically safe classification of that radio product, and the approved
batteries that can be used with that system.
The manual PN referenced on the Intrinsically Safe Approval Label
identifies the approved Accessories and or options that can be used
with that portable radio unit.
Using a non-Motorola-intrinsically-safe battery and or accessory with
the Motorola approved radio unit will void the intrinsically safe
approval of that radio unit.
