Operating Instructions
The HEXEH alarm clock features simple controls located on the back of the unit.
Setting the Current Time
- Locate the "TIME SET" knob on the back of the clock.
- Rotate this knob in either direction until the hour and minute hands display the correct current time.
Setting the Alarm Time
- Locate the "ALARM SET" knob on the back of the clock.
- Rotate this knob to set the desired alarm time. The alarm hand will move independently.
- Ensure the alarm ON/OFF switch (usually a small slider or button) is in the "ON" position to activate the alarm.
Note: The alarm will sound at the set time. To stop the alarm, move the alarm ON/OFF switch to the "OFF" position. The alarm will reset for the next day if the switch remains in the "ON" position.
Luminous Feature
The hour and minute hands, along with the hour markers, are coated with a luminous material. After exposure to light, these elements will glow in the dark, allowing for easy time-telling at night without needing to turn on a light. The intensity and duration of the glow depend on the amount and duration of light exposure.
Maintenance
- Cleaning: Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the finish or internal components.
- Battery Replacement: Replace the AA battery approximately once a year, or when the clock starts to lose time or the alarm weakens.
- Environment: Avoid placing the clock in direct sunlight, extreme temperatures, or high humidity, which can affect its accuracy and lifespan.
