This document describes the V18039 Digital Alarm Clock, a versatile device designed for timekeeping, alarm functions, and environmental monitoring.

Function Description:

The V18039 alarm clock serves multiple functions:

• Time Display: It displays the current time in either 12-hour (AM/PM) or 24-hour format.
• Alarm Functionality: It features three independent alarms (Alarm 1, Alarm 2, Alarm 3) that can be set for different schedules: every day (MON-SUN), weekdays only (MON-FRI), or weekends only (SAT-SUN). Each alarm has an adjustable volume with five levels (V1-V5).
• Snooze Feature: When an alarm goes off, pressing any button activates a 9-minute snooze. This function automatically shuts off after four consecutive uses.
• Environmental Monitoring: The clock includes built-in sensors to display the current indoor humidity level (in %RH) and temperature (in Celsius or Fahrenheit).
• Brightness Adjustment: The display brightness can be adjusted through six levels (L1-L6), ranging from 2% to 100%.

Important Technical Specifications:

• Power Input: Type-C USB for power. It requires an input voltage of AC110V-240V, 50/60HZ, and an output voltage of DC5V / 500MA-2100MA. The original power cord and adapter are recommended, but a 5V 1A or 5V 2A adapter can be used as a replacement.
• Battery Backup: A CR2032 battery is included to retain alarm settings and the current time during power outages, preventing the need for re-setting after power is restored.
• Temperature Sensor: The internal temperature sensor provides indoor temperature readings. It's noted that due to internal electronic components, there might be a 1-2 degree difference compared to professional thermometers. A difference higher than 5 degrees warrants contacting customer support.
• Humidity Sensor: An internal sensor detects and displays indoor humidity levels.

Usage Features:

• Time Setting: Hold the "TIME" button, then use the scroll wheel to set the year, date, and time.
• Volume Adjustment: Press the "VOL" button once, then use the scroll wheel to select one of the five volume levels (V1-V5).
• Temperature Unit Switch: Press the "°C / °F" button to toggle between Celsius and Fahrenheit display. This button can also be used to exit the setting menu.
• Alarm Setting:
  • Press an "Alarm" button (ALARM1, ALARM2, or ALARM3) once to turn the alarm ON or OFF.
  • Hold an "Alarm" button to enter the alarm setting mode. The alarm will be turned ON by default after setting.
  • Use the scroll wheel to set the alarm time.
  • Select the alarm mode (MON-SUN, MON-FRI, or SAT-SUN) using the Alarm Mode Switch.
• 12/24H Display Switch: A dedicated switch allows easy toggling between 12-hour and 24-hour display modes.
• Brightness Adjustment: In normal status, turn the scroll wheel to adjust the display brightness through six levels.
• Reset Function: A "RESET" button (accessible with a small stick) is available to initialize the clock if it malfunctions.

Maintenance Features:

• Lifetime Warranty Service: The product comes with a lifetime warranty. Activation is available by visiting www.jall-us.com.
• Customer Support: For missing accessories, incorrect color, or any other problems, customers can contact Three DucksDirect@outlook.com.
• CR2032 Battery Replacement: If the clock fails to restore settings after a power outage, the CR2032 battery may be drained and needs replacement. The battery shelf is located on the back of the clock.
• Power Cord and Adapter: It is recommended to use the original power cord and adapter. If it's broken or missing, contact customer support for a replacement. Using a non-original power cord and adapter may cause malfunctions or damage.
• Troubleshooting:
  • For dimming or flashing numbers, take a picture or video and contact customer support.
  • If the screen is not lit, try unplugging and reconnecting the power cord, then pressing the RESET button. If the issue persists, contact customer support.
  • Temperature sensor inaccuracies (beyond 5 degrees) should be reported to customer support.
