hi, im assuming you have the manual?
if not here is an online verson in pdf format, mainly for the button layout of your radio...
http://www.radiolabs.com/downloads/manuals/grundig/S350_manual.pdfPlus there is more specific information regarding setting the time and alarm at chapter 11 and 13.
SETTING THE TIMEThe radio must be switched off.
With the radio off hold down the "TIME" button for 3 seconds and then release it, the time display will flash.
Whilst it is flashing, press the hour and minute button until the correct time is shown, immediatly press the "TIME" button to finalize the entry.
If the "TIME" button is not pressed the radio will automatically finalize the time after 5 seconds.
SETTING THE ALARMWith the radio powered off, hold down the "ALARM" button for about 3 seconds or until the digits start flashing, then release it.
While they are still flashing, press the "HOUR" and "MINUTE" buttons to set the turn on time, then immediatly press the "ALARM" button.
To activate/de-activate the turn-on-timer, press the AL on/off button, causing the symbol of a speaker to appear in the upper right of the display.
When the speaer is on the screen the ALARM is activated, when it is not on the display the ALARM is de-actiaved.
To see the Turn-on-Time, with teh radio on or off, press the ALARM button, The turn on time will display for about 4 seconds..
I hope this helps
Regards.
Mike
