2. Setup
2.1 Battery Installation
- Locate the battery compartment cover on the back of the clock.
- Carefully remove the battery compartment cover. Note: The cover may require gentle prying or sliding.
- Insert one CR2 battery, ensuring the positive (+) and negative (-) terminals are aligned correctly according to the diagram inside the compartment. A CR2 battery is included with your clock.
- Replace the battery compartment cover securely.
2.2 Setting the Time
- Locate the time setting knob on the back of the clock.
- Rotate the knob in either direction to move the hour and minute hands until the desired time is displayed.
2.3 Setting the Alarm
- Locate the alarm setting knob on the back of the clock. This is typically a smaller knob or a tab.
- Rotate the alarm setting knob to move the alarm hand to your desired alarm time. Note that the alarm hand moves in increments, often corresponding to 10-minute intervals.
- Ensure the alarm activation switch (if present, often a small tab or slider) is in the "ON" position to enable the alarm.
3. Operating the Clock
3.1 Alarm Activation and Deactivation
- To activate the alarm, slide the alarm switch (usually on the side or back) to the "ON" position.
- When the alarm sounds, slide the alarm switch to the "OFF" position to stop it.
3.2 Luminous Display
The hands and markers of your Casio TQ140 clock are treated with a luminous material. For optimal glow in the dark, expose the clock face to a bright light source (natural or artificial) for a period before viewing in low-light conditions. The intensity and duration of the glow will depend on the exposure to light.
4. Maintenance
4.1 Battery Replacement
When the clock's timekeeping becomes inaccurate or the alarm weakens, it is time to replace the battery. Follow the steps outlined in Section 2.1 "Battery Installation" to replace the CR2 battery. Always dispose of used batteries responsibly.
Important: If the clock will not be used for an extended period, it is recommended to remove the battery to prevent potential leakage and damage to the clock's internal components.
4.2 Cleaning
To clean the clock, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the clock's finish or internal parts.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not running or running slowly. | Depleted battery. | Replace the CR2 battery (refer to Section 4.1). |
| Alarm does not sound or sounds at the wrong time. | Alarm switch is OFF. Alarm time set incorrectly. Weak battery. | Ensure alarm switch is ON. Re-set the alarm hand carefully (refer to Section 2.3). Note that analog alarm settings can have slight variations. Replace the battery. |
| Luminous display is dim or short-lived. | Insufficient exposure to light. | Expose the clock face to a bright light source for a longer period before viewing in the dark. |
| Audible ticking sound. | Normal operation of the analog movement. | This is characteristic of some analog clocks. If the sound is disruptive, consider placing the clock in a different location. |
