Removal
1. Remove the bottom housing assembly (refer to Bottom Housing operation).
2. Disconnect the scan switch/speaker harness from the main logic board.
3. Using a T7 torx driver remove 4 screws that secure the scan bracket to the core assembly.
4. Gently lift the scan bracket away from the core assembly and disconnect the antenna coax from J4 on the main
logic board.
NOTE: On units without a WAN radio this coax will come from the top housing assembly, not the scan bracket
assembly.
5. Disconnect the scan engine flex cable and camera flex cable from the main logic board.
The scan bracket assembly can now be serviced itself or set aside to be re-installed later. If the base scan bracket
assembly is being replaced you will remove the WAN/WiFi antenna, EA30 scan engine, camera, and side scan
PCB’s and transfer them to the replacement base scan bracket assembly. See the EA30 Scan Engine, WAN/WiFi
Antenna, Camera, and Side Scan PCB operations for tools, parts, & procedures related specifically to those items.
