4. Setup

4.1 Powering the Device

The clock can be powered in two ways:

1. USB Power: Connect the provided USB cable to the DC 5V/500mA port on the back of the clock and plug the other end into a USB power adapter (not included) or a computer USB port. This mode allows for continuous display.
2. Battery Power: Insert 3 AAA batteries (not included) into the battery compartment on the back of the clock, observing the correct polarity (+/-). In battery mode, the clock will typically enter voice control mode to conserve power, meaning the display will turn off after a short period and can be activated by sound.

5. Operating Instructions

The clock features several buttons on the back for configuration. Refer to the labels on the device for specific button functions (e.g., SET, UP, DOWN).

5.1 Basic Settings (Time, Date, Temperature Unit)

1. Press the SET button to enter setting mode.
2. The first setting will typically be the year. Use the UP and DOWN buttons to adjust the value.
3. Press SET again to confirm and move to the next setting (Month, Day, 12/24 Hour Mode, Hour, Minute, Temperature Unit C/F).
4. Repeat the process until all desired settings are configured.
5. The clock will automatically exit setting mode if no buttons are pressed for a few seconds.

5.2 Setting Alarms

The clock supports up to three independent alarms (AL1, AL2, AL3).

1. Press the SET button repeatedly until "AL1" (or AL2, AL3) appears on the display.
2. Press SET again to enter alarm setting mode for AL1. The hour will flash.
3. Use UP and DOWN to set the desired alarm hour. Press SET to confirm.
4. Set the alarm minute using UP and DOWN, then press SET to confirm.
5. After setting the time, you can enable or disable the alarm. Use UP or DOWN to select "ON" or "--" (OFF). Press SET to confirm.
6. Repeat for AL2 and AL3 if needed.

When an alarm sounds, press any button to snooze or turn off the alarm. If no button is pressed, the alarm will automatically turn off after a set duration.

5.3 Brightness Adjustment

The clock offers 3 levels of brightness.

• In normal time display mode, press the UP button to cycle through the brightness levels.

5.4 Display Modes (Voice Control / Always-On)

The clock has two main display modes:

• Voice Control Mode (Power Saving): When powered by batteries, this mode is recommended. The display will turn off after approximately 10 seconds to save power. To activate the display, make a sound (e.g., clap your hands, tap the clock) or touch the clock.
• Always-On Display Mode: When powered by USB, the display can remain continuously on. Refer to the device's specific button (often the DOWN button or a dedicated "MODE" button) to switch between display modes if available.
