| Configurations |
The basic TX/RX unit can be configured as a dash-mount radio by plugging either the 70-2202 or 70-2203 control head into the front of the unit. It can be configured as a trunk-mount radio with a trunk-mount front cap and cable, and either the 70-2202 or 70-2203 control heads mounted as remote control heads. |
