Installation & Setup

Unpack and inspect contents. Place clock on a stable, flat surface near a window for optimal solar charging and radio signal reception.

Insert Batteries: Open battery compartment, install fresh alkaline batteries as indicated (+/-).
Position Solar Panel: Ensure solar panel faces a light source (indoor or indirect sunlight).
Initial Power-Up: Clock will display default time; wait for radio signal reception.
Placement: Avoid metal surfaces, electronic devices, or obstructions that may block signal.

WARNING! Use only recommended battery types. Do not expose to extreme temperatures or moisture.

First-Time Configuration

After power-up, the clock will attempt to receive the radio signal automatically.

Wait for Signal: Allow up to 10 minutes for initial synchronization (signal icon will flash).
Manual Setup (if needed): Press and hold SET button to enter manual mode; adjust time, date, format.
Set Alarms: Press ALARM button, then use +/- to set alarm time; repeat for second alarm.
Configure Backlight: Press LIGHT button to adjust brightness or set auto-on duration.
Select Temperature Unit: Press °F/°C button to toggle between Fahrenheit and Celsius.

CAUTION! Ensure clock is within range of WWVB signal (typically up to 2000 miles from transmitter).

Controls and Settings

Front Panel Buttons: SET, ALARM, LIGHT, SNOOZE, °F/°C, +/-, and MODE.

Button Functions: SET enters configuration; ALARM sets alarm times; LIGHT controls backlight; SNOOZE activates snooze; °F/°C toggles temperature unit; +/- adjusts values; MODE cycles display modes.

Menu Settings: Time format (12/24 hr), date format (MM/DD or DD/MM), backlight duration (off, 5s, 15s, 30s), alarm tone (beep, radio), signal reception mode (auto, manual).

Solar Panel Operation

The solar panel provides supplemental power and charges the internal backup battery.

Ensure solar panel is exposed to light (direct or indirect).
LED indicator may show charging status (if equipped).
In sufficient light, solar power reduces main battery consumption.
Backup battery maintains time and settings during main battery replacement.

Tip: Clean solar panel periodically with soft, dry cloth to maintain efficiency.

Alarm Functions

Dual alarms with adjustable tone and snooze.

Set Alarm: Press ALARM, select alarm 1 or 2, use +/- to set hour/minute, press ALARM to save.
Activate/Deactivate: Press ALARM button to toggle alarm on/off (icon shows status).
Snooze: When alarm sounds, press SNOOZE to silence for 5-10 minutes (repeatable).
Alarm Tone: Choose between beep or radio (if radio alarm feature is available).
Wake to Radio: If supported, alarm can activate radio at set volume.

WARNING! Do not rely solely on alarm for critical events; use backup alarm if needed.

Radio Signal Reception

Clock automatically searches for WWVB signal nightly; manual reception available.

Signal Icon: Flashes during search, solid when synchronized. If signal is weak, move clock closer to window or away from interference. Manual Sync: Press and hold SET for 3 seconds to force signal search. Factors affecting reception: distance from transmitter, obstacles, weather, electronic interference.

Care & Maintenance

Use soft, dry cloth for cleaning. Avoid chemicals or abrasives.

CAUTION! Do not immerse in water; keep away from heat sources and direct sunlight for extended periods to avoid display damage.
