The schematic clearly outlines the Alive (ALW) rails. On the MBX252, the RTC cell powers the CMOS. When the AC adapter is plugged in, the +3.3V_ALW and +5V_ALW are generated by the MAX8734A or similar PWM chip. The schematic shows the exact resistor dividers for the adapter detection (ACOK) signal. A common fault here is a failed capacitor on the LDO output.
The MB-252 facilitates power transfer through screw terminals or direct wiring depending on the specific radio model revision it is paired with.
