Batteries

 The Micro USB cord is the best power source for the projection alarm clock.

If you choose to use batteries:

 Use 2 AAA alkaline batteries.

 Half of all warranty issues can be resolved with fresh batteries of the appropriate

voltage.

 Use batteries dated at least six years in advance of the current year. Batteries

dated earlier than six years from now may still work, but may be unstable in

performance.

 Alkaline batteries manufactured this year will have an expiration date 10 years

in the future. Battery technology has improved and batteries will maintain

voltage longer in storage. However, the environment the batteries reside in for

the 10 years can deplete the power.

This document provides a comprehensive guide for the 616A-1908 Projection Alarm Clock, covering its functions, usage, and maintenance. It is designed to help users understand and troubleshoot their device effectively.

Function Description

The 616A-1908 is a versatile projection alarm clock primarily powered by a Micro USB cord, though it can also operate on batteries. Its core function is to display time, which can be projected onto a wall or ceiling for easy viewing. The clock includes an alarm feature with snooze capabilities, a backlight for the LCD display, and a USB charging port for external devices. It also allows for manual setting of time and calendar information.

Usage Features

Power Source:

The device operates optimally when connected via the Micro USB cord. If using batteries, it requires two AAA alkaline batteries. It is crucial to use fresh, good-quality batteries with a minimum voltage of 1.48V for proper performance. Batteries dated at least six years in advance of the current year are recommended to ensure stability. Good brand-name batteries also help reduce RF interference.

Clock Factory Restart:

In case of persistent issues, a factory restart can resolve many problems. To perform a factory restart:

Remove both batteries and the Micro USB cord.
Press any button on the clock at least 20 times to clear all memory, ensuring the clock display is blank.
Leave the clock unpowered for at least 10 minutes.
Insert fresh alkaline batteries.

Time Display:

The time numbers on the display are 0.86 inches tall. Users can choose between a 12-hour or 24-hour time format, with 12-hour being the default. The time format can be changed via the Program Menu.

Projection Feature:

When powered by the Micro USB cord, the time will project continuously. In battery operation, pressing and releasing the SNOOZE/LIGHT button will activate the projection for 3 seconds; continuous projection is not available on battery power. The projection arm can rotate 180 degrees to direct the projection onto a wall or ceiling. The projected time can also be rotated in 90-degree increments by pressing and releasing the UP button.

Setting the Time Alarm:

To set the alarm:

Hold and release the ALARM button to enter time set mode; the alarm hours will flash.
Use the UP or DOWN buttons to adjust the hour (hold for quick adjustment).
Press and release the ALARM button to confirm the hour and move to minutes; the alarm minutes will flash.
Use the UP or DOWN buttons to adjust the minutes (hold for quick adjustment).
Press and release the ALARM button to confirm and exit.

Activating/Deactivating the Time Alarm:

To view the alarm time, press the ALARM button once. Pressing it again will activate the alarm, indicated by a bell icon. Pressing it a third time will deactivate the alarm, and the bell icon will disappear.

Snooze Alarm:

When the alarm sounds, press the SNOOZE/LIGHT button to silence it for 10 minutes; "Zz" will appear above the time. To stop the alarm for one day while in snooze mode, press SNOOZE/LIGHT again. The alarm features a crescendo sound and will automatically shut off after 2 minutes if not silenced.

Backlight (HI-LOW-OFF):

The LCD backlight has three stages: HI, LOW, and OFF. Press the SNOOZE/LIGHT button to cycle through these brightness settings.

USB Charging:

The clock includes a power-output USB charging port. When the clock is plugged into a USB outlet with the Micro-USB cord, it can charge smartphones, cameras, or other devices. This port does not supply power to the clock itself. Note that mobile devices cannot be charged when the clock is operating on battery power. Users will need their mobile device's USB charging cable (not included). Charging times may vary.

Manually Setting Time/Calendar/Alarm (Program Menu):

To access the Program Menu:

Hold the MODE/SET button for five seconds. "12H" will flash.
Use the UP or DOWN buttons to select 24-hour time format.
Press MODE/SET to confirm and move to hours; hours will flash.
Use the UP or DOWN buttons to set the hours.
Press MODE/SET to confirm and move to minutes; minutes will flash.
Use the UP or DOWN buttons to set the minutes.
Press MODE/SET to confirm and move to the year; year will flash.
Use the UP or DOWN buttons to set the year.
Press MODE/SET to confirm and move to the month; month will flash.
Use the UP or DOWN buttons to set the month.
Press MODE/SET to confirm and move to the date; date will flash.
Use the UP or DOWN buttons to set the date.
Press MODE/SET to confirm and exit. The day of the week sets automatically once the year, month, and date are configured.

Displaying Date or Alarm Time:

Press the MODE/SET button to toggle between displaying the Alarm Time and the Calendar.

Maintenance Features

Troubleshooting Incorrect Time:

If the time is incorrect, it is likely due to manual setting. Enter the Program Menu to adjust the time.

Troubleshooting Missing Segments on Display:

Missing segments usually indicate a power-related issue.

Remove batteries from the clock.
Press any button 20 times.
Leave the clock unpowered for 1-2 hours.
Insert fresh alkaline batteries with correct polarity.

Troubleshooting a Dim Clock Display:

Most clocks have a gray background. If the display appears dim, check it at eye level. Clocks exposed to sunlight can develop a cloudy film over time. Dimness is often a power-related issue.

Ensure the AC cord is plugged in correctly.
If using batteries, they might be overpowered or underpowered. Remove both batteries and the AC cord.
Press any button 20 times.
Leave the clock unpowered for 1-2 hours.
Reinstall the AC cord and/or fresh alkaline batteries with correct polarity.

Troubleshooting a Distorted Display:

For a brand-new clock with a distorted display, check for thin plastic films of printed scratch guard on the upper and lower screen. These films often have printed numbers for store displays and can be easily peeled off the LCD. With all power removed, the clock should be blank. If numbers still appear, a scratch guard is likely present.
