Display Brightness Control

This SmartSet® Clock Radio features a unique display brightness control system that gives you three convenient options:

HIGH – when the dimmer switch is set to the “HIGH” position the clock display is always at full brightness. The dimmer switch was set to the ‘High’position at our factory.

LOW – when the dimmer switch is set to the “LOW” position the display brightness is reduced by approximately 50%.

OFF/WAVE– when the dimmer switch is set to the “OFF/WAVE” position the display goes ‘Off’completely. This is designed for people who prefer to sleep in total darkness. However if you want to see the clock display at any time, slowly wave your hand in front of the WAVE SENSOR on the front panel. The clock display will immediately return to full brightness for 10 seconds and then shut off again automatically. The effective operating range of the Wave Sensor

is approximately 12” to 36” from the front panel.

NOTES:

A.) The clock radio must be at room temperature for the WAVE SENSOR to function properly. If the radio has been in a cold location the WAVE SENSOR may not operate immediately. Place the radio in the room where it will be used, connect it to the AC outlet, and allow approximately 30 minutes to 60 minutes for the radio to come to room temperature before testing the WAVE SENSOR function.

B.) If the dimmer switch is set to the “OFF/WAVE” position the display will be completely off. However at the Alarm time the display will return to full brightness automatically. It will remain at full brightness for one hour and then return to the ‘Off’position. If you stop the alarm immediately by pressing the respective Alarm 1 or Alarm 2 buttons, or set the Alarm 1 or Alarm 2 switches to their “OFF” positions, or use the SNOOZE control, the display will return to the ‘Off’position after 10 seconds.
