AcuRite 13131A3 Atomic Alarm Clock Instruction Manual

Quick guide from the manual

This document provides essential instructions for setting up and operating your AcuRite Atomic Alarm Clock. Key tasks include installing batteries, configuring time and alarm settings, and ensuring optimal placement for atomic signal reception. Please note that the atomic signal may take a few hours to synchronize; manual time setting is recommended immediately after powering on the device.

Clock Setup

To set up the clock, remove the protective film from the LCD screen. Install 3 x AA alkaline batteries into the compartment on the back, ensuring correct polarity as indicated by the diagram. Replace the battery cover.

Atomic Clock

The clock uses a radio-controlled signal (RCC) from the NIST Radio Station WWVB to synchronize time and automatically update for Daylight Saving Time. For best signal reception, place the clock away from large metallic objects, thick walls, and electronic devices like TVs or microwaves. Reception is typically better at night and during clear weather.

Set the Time & Date

Press and hold the SET CLOCK button to enter SET MODE. Use the up and down arrow buttons to adjust flashing values. Press SET CLOCK to save and move to the next preference in this order: Time Zone, Auto DST (ON/OFF), Calendar Year, Month, Date, Hour, and Minute. The device will exit SET MODE automatically after 45 seconds of inactivity.

Using the Alarm Clock

To set the alarm time, press and hold the ALARM ON/OFF button for 5 seconds. Use the arrow buttons to adjust the hour and minute, pressing ALARM ON/OFF to confirm. To turn the alarm on or off, press and release the ALARM ON/OFF button until the alarm icon and status appear on the display. When the alarm sounds, press the SNOOZE/LIGHT button to activate the 8-minute snooze function.

Care & Maintenance

Clean the device with a soft, damp cloth. Avoid caustic cleaners or abrasives. Keep the unit free from dust, dirt, and moisture. Regularly clean ventilation ports with a gentle puff of air.

Troubleshooting

If the display is dark or hard to read, verify battery installation or replace them. For inaccurate temperature readings, ensure the clock is away from direct sunlight, heat sources, or vents. If the atomic signal fails to sync, check the placement guidelines or visit the NIST website for further information. A full factory reset can be performed using the RESET button in the battery compartment.
