DUAL RADIO UNITS

The Dual Radio feature can be configured either for two remote mount radio units or one front mount unit and one remote mount unit. In remote mount configurations the Control Unit is typically located in the vehicle cab, with the Radio Units located side-by-side in vehicle trunk. In front/remote mount configurations the front mount unit is located in the vehicle cab, with the remote mount unit located in a convenient location nearby. The remote/remote mount configuration is the preferred installation, since a separate control unit is required to program the remote unit in a front/remote mount configuration.

The following Dual Radio Unit configurations are not allowed:

1.Any configuration using a DIN cassette mount.

2.Any installation where Extended Options are required from both Radio Units. Extended Options are supported in one Radio Unit only.

PRE-INSTALLATION PROGRAMMING

PROCEDURE

All Radio Units in the Dual Radio configuration MUST BE PROGRAMMED prior to final installation. It is recommended that the units be first programmed at a Service Center, then transferred to the user's installation.

These configurations provide for a Master Radio Unit and a Slave Radio Unit. In the remote/remote mount configuration, the Master Radio Unit is always the radio most directly connected to the Control Unit. In the front/remote mount configuration, the Master Radio Unit is always the front mount radio. Extended Options are allowed only in the Master Radio Unit. Programming each radio is straightforward, except that one radio is programmed as a Master, and one as a Slave.

1.Decide which Radio Unit shall be the Master Unit. Configure the radio for programming as shown in the applicable service section manual.

2.In the "Multi-Radio" field of the PC programmer, select "Master".

3.Program unit normally. Include Extended Option features, if purchased.

4.Now configure the "Slave" Radio Unit for programming. Be sure to use the programming configuration for remote mount, and supply the required control unit, if for a front/remote mount dual radio configuration.
