To begin using your NeXus-4 device, a crucial step involves setting up its power source. Follow these detailed instructions:
1. Locate the battery compartment situated on the device's rear. You'll find it by identifying a marked area specifically designed for interaction at the bottom part of the battery cover. Press this area firmly.
2. While maintaining pressure, slide the cover in a backwards motion to remove it and expose the battery compartment.
3. Observe the internal instructions detailed within the compartment for proper battery orientation. Insert two AA batteries accordingly.
4. Once the batteries are securely in place, reattach the battery cover by aligning it with the compartment and sliding it towards the device until it clicks, indicating it is securely fastened. This step completes the power setup for your NeXus-4, preparing it for subsequent use and operation.
