HOW TO USE THE TIMER

Set the timer by pressing the POWER ON button.
With each push of the button, the TIMER indicator
lights up showing the selected timer duration (60, 45,

The radio will turn itself off automatically after the
preset time has elapsed.

OFF button.

Note: There might be about 115% deviation of timer
duration.

For improved reception

The built-in ferrite bar antenna (for AM) or the print
pattern antenna (for TV and FM) activates. Change
the direction of the unit for optimum reception.

If noise still makes it hard to hear the FM program,
connect the FM wire antenna (supplied) to the WIRE
ANT terminal using the screw (supplied) and extend
it as long as possible.
