LA CROSSE TECHNOLOGY 404-1236 (01) PDF MANUAL

Step 1: Slide the switch to select a time zone.

Step 2: Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to the polarity marked on the case.

Step 3: Position the clock on an exterior wall that faces Ft. Collins Colorado. During the night, your clock will automatically set itself.

The hands will move to the 12:00 position and search for the radio signal. If the radio signal is not received in the first 10 minutes, the clock will start running from the 12:00 position and will continue to run. Do not attempt to reset the hands manually even though the time on the clock is incorrect. The clock is synchronizing to the WWVB signal and once the radio signal is decoded, the hands will automatically adjust to the correct time. This may take up to 5 nights.

Choose a location 6 feet or more from electronics such as cordless phones, wireless gaming systems, televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.

Position near an exterior wall that faces Ft. Collins Colorado for WWVB time signal reception.

The antenna is available for signal reception when the front or back of the clock faces Colorado.

If the clock does not respond to the various function modes, reset the clock by pressing the RESET button on the movement case.

A good AA alkaline battery will last over 24 months. It is recommended that you change the battery every 24 months to maintain accuracy. Remove the battery when the clock will not be in use for an extended period.

Allow up to five nights for the clock to receive the WWVB signal before manually setting the time.

To set the clock manually:

Press and hold the SET button for 3+ seconds to activate the manual mode. Once the clock is in manual mode, there are two ways to move the minute hand forward.

Hold the SET button down to move the minute hand forward consistently.

Alternatively, press the SET button rapidly (more than once per second) to move the minute hand forward step by step (in minute increments).

Use these features to move the minute hand forward until the correct time is set. The clock will automatically leave manual mode after the SET button is not pressed for 6+ seconds.

If the clock does not receive a time signal, consider the following:

Battery – The clock must have a fresh battery to receive and process the time signal.

Location – Try a different location, ideally near a window. Your clock should be at least six feet from computers, TVs, air conditioners, other radio-controlled clocks and other electrical appliances that cause interference.

Weather – Electrical storms between you and Colorado during the night will interfere with the WWVB signal.

The National Institute of Standards and Technology and WWVB encode a special DST “bit” in the WWVB transmission for DST. Your clock will read this information and automatically advance the hands one hour in the spring and eleven hours in the fall.

If you live in an area that does not recognize DST, you must slide the DST switch OFF. To reactivate the DST program simply slide the switch to the ON position.

The WWVB signal is strongest at night.

Hold the WAVE button down for 3+ seconds.

The hands will automatically reset to the 12:00 position, and the movement will attempt to enforce a signal receipt from Fort Collins, CO.

If the movement successfully receives the signal, the clock will reset automatically to the correct time. The enforced signal receipt takes approximately 3-8 minutes. If the clock still fails to receive the signal while in the WAVE mode, the clock will automatically leave the WAVE mode.

Set the clock manually and the movement’s micro-CPU will control the time keeping function.

Once the clock has set correctly by the radio signal, the clock’s CPU operates continuously. To ensure accuracy, the clock synchronizes the position of the second and minute hands to the time calculated by the CPU every day. Second hand synchronization occurs at 1:30 a.m. and 9:30 a.m. and minute hand synchronization occurs between 1:50 and 2:01 am every day.

In some cases, the signal is affected by weather conditions and electrical interferences, or the location of the clock itself may result in poor reception. If the clock has not synchronized to the correct time within a few days of activation, you may need to move the clock to a different location.

No, the clock cannot work on a timing circuit. Opening the clock voids the warranty.

No, the clock cannot work with a booster antenna. Opening the clock or movement voids the warranty.

No. If you manually set the time, when the clock receives a WWVB signal, that signal will override the manual set. The WAVE button will temporarily stop a WWVB search, but will not permanent stop the clock from receiving a WWVB time signal.

La Crosse Technology® does not make an analog clock with more than four time zones. These time zones are P (Pacific Time), M (Mountain Time), C (Central Time), and E (Eastern Time).

When the hands spin about the same time every day the clock is auto-correcting the time. The hour hand should not spin more than twice around the clock.

Hands may spin if the battery is under powered or over powered. Use only Alkaline batteries in the clock.

Do not mix old and new batteries.

Do not mix Alkaline, Standard, Lithium or Rechargeable Batteries.

Do not expose to extreme temperature, vibration or shock.

Clean with a soft damp cloth. Do not use solvents.
