The empty parentheses at the end of

the kit numbers and part numbers

mentioned throughout this document

stand for the alphabetical character (A,

B, etc.) that denotes the revision level

of the kit or part. The revision level of

the kits and/or parts may change from

time to time without affecting the

validity of these retrofit instructions.

This document describes and provides user instructions for Motorola

retrofit kit numbers H1634( ) and H1635( ).

Purpose of Retrofit

Kits

The purpose of the retrofit kits is to enable conversion of an MCS 2000

radio that is in the dash/local mounting configuration to the remote

mounting configuration.

The difference between the two kits is the particular radio models to

which each applies.

In the dash/local mounting configuration, the control head of the

radio is attached directly to the radio body and the radio is situated in

thevehiclesothatitscontrolsandindicatorsareaccessibletotheradio

user.

In the remote mounting configuration, the control head of the radio

ismounted where itscontrols and indicatorsare accessible tothe radio

user.However, the radiobody is mountedin the trunkor other remote

location in the vehicle.

There are two situations where these retrofit kits are used. The first is

where the radio body remains where it is presently located (e.g., under

the front seat or on the transmission hump) and just the control head

is moved to a different location (e.g., under the dashboard). The other

situationis where both the radio body and the control headare moved

to different locations.
