The front of the chassis has an aperture for the control-head connector.
The control-head seal is fitted inside a groove around the flange at the front
face of the chassis and provides for IP54 class protection when the control
head is fitted. Two dot-dash-dot marks at the underside side of the chassis
indicate the leverage points for removing the control head from the
radio body.
The sides of the chassis contain two of the four screw bosses to attach the
radio to the U-bracket of the installation kit.
For heat dissipation, the chassis has heat fins at the rear, grooves at the
bottom, and holes in the front.
The heat fins at the rear of the >25W radio are longer than those of the
>25W 25W
25W radio. The grooves at the bottom of the >25W radio are deeper than
those of the 25W radio.
For additional heat dissipation, the >25W radio has an additional L-shaped

gap pad between the chassis and the main board.
