How to replace the battery
Make sure the radio is turned off, and that nothing is connected to the radio USB-C and Audio ports. Disassemble the back lid by removing the six screws. Use a standard small Philips screwdriver for this and turn counterclockwise. Carefully disconnect the battery from the circuit board battery connector. Carefully and slowly pull the tab of the removable double adhesive tape strip until the battery falls off. Remove the tape protection of the new battery and mount it to the Lid in the same position as the old battery. Press and hold the battery for a few seconds to make sure it sticks to the lid properly. Gently connect the new battery to the battery connector on the circuit board. Note that the connector will only fit in one direction. Place the lid on the table with the battery facing upwards. Check that the sealing gasket is in its correct position. Mount the unit to the lid and make sure you have a good fit. Turn the radio with lid around and insert the six screws. Make sure to not use too much force when tightening the screws. When a small resistance is felt, and there is no gap between the lid and unit, the tightening is ok.
