1.1 Mobile Radio Description
1.1.1 Dimensions
Figure 1-1 and Figure 1-2 show the basic dimensions of the dash mount transceiver trunnion XTL
2500 radio. The transceiver portion of a remote mount XTL 2500 is sized similarly.
When installing the radio, make sure to plan the installation carefully and leave additional room in the
rear of the radio for cabling and accessory connections; in the front of the radio for access, controls,
and cabling (if remote mount); and to the sides of the radio so that you may access and install the
trunnion wing screws.
NOTE: The rear accessory connector adds 0.75 in. to the overall length.
