PREPARATION FOR USE
This clock radio includes a battery backup system that will maintain the time and
alarm settings during a temporary power interruption. Insert two ‘AAA’ size batteries
correctly by matching the polarity (+/-) markings in the battery compartment (10). If

you experience a power failure while batteries are installed, the display will turn ‘off’

but the clock will continue to run and maintain your alarm settings. Please replace all
batteries at the same time with only new batteries.

The clock radio has slip proof silicon feet. Place the clock radio only on protected
furniture.
Plug AC plug (12) into 230vac electrical outlet.

Unwind the FM antenna (11) on the back of the clock radio. Extend and reposition
the antenna for best radio reception.
