Introduction
Thank you for purchasing the Sami RS-4734 Digital Radio Alarm Clock. This device combines a digital FM radio with a dual alarm clock, offering convenience and functionality for your daily routine. Please read this manual carefully to ensure proper use and to get the most out of your new device.

Setup
- Power Connection: Connect the included transformer to the DC input port on the back of the radio clock and plug it into a standard wall outlet.
- Battery Backup: For time and alarm settings retention during power outages, insert two (2) AA batteries (not included) into the battery compartment located on the bottom of the unit. Ensure correct polarity (+/-).
- Initial Time Setting: Upon first power-up or after a power outage without backup batteries, the display will flash. Use the time setting buttons (usually labeled 'Time Set' or 'Hour/Minute') on the top panel to set the current time. Refer to the button layout on the device for specific controls.
- Radio Antenna: Extend the FM wire antenna (if present) for optimal radio reception.
