Casio SPF-10 Watch User Manual

Important Information

Please read this important information before use.

Battery

The battery is factory-installed and should be replaced immediately when power is low (e.g., backlight dim, display faint) by an authorized CASIO dealer or distributor.

Water Resistance

Watches are classified by water resistance levels (I to V). Refer to the table below for proper usage.

Notes for levels:

• Level I: Not water resistant. Avoid all moisture.
• Level II: Do not pull out the crown when the watch is wet.
• Level III: Do not press buttons underwater.
• Level IV: If exposed to saltwater, rinse thoroughly with fresh water and dry.
• Level V: Suitable for scuba diving (excluding saturation diving requiring helium-oxygen mix).

Some water-resistant watches have leather bands. Do not wear these watches while swimming or engaging in activities where the band may get wet.

Care for Your Watch

• Never attempt to open the case or remove the back cover.
• The gasket (water/dust seal) should be replaced every 2-3 years.
• If water enters the watch, have it checked immediately by a CASIO dealer.
• Avoid extreme temperatures.
• While designed for normal use, avoid rough handling or dropping.
• Do not overtighten the band. A finger should fit between your wrist and the band.
• Clean with a dry, soft cloth, or a soft cloth dampened with a mild neutral detergent solution. Never use volatile substances (e.g., benzine, solvents, spray cleaners).
• Store in a dry place when not in use.
• Avoid contact with benzine, cleaning solvents, spray aerosols, adhesives, paint, etc. These can cause chemical reactions damaging gaskets, case, and finish.
• Be careful when cleaning bands with silk-screened designs to avoid damaging the graphics.

For Watches with Plastic Bands...

• A white powdery substance may appear on the band. This is harmless and can be wiped off with a cloth.
• Sweat or moisture, or storage in high humidity, can cause damage, tearing, or cracking. To prolong band life, wipe off dirt and moisture with a soft cloth when possible.

For Watches with Fluorescent Cases and Bands...

• Prolonged exposure to direct sunlight can cause fluorescent colors to fade.
• Prolonged contact with moisture can cause fluorescent colors to fade. Wipe off any moisture promptly.
• Prolonged contact with other wet surfaces can cause fluorescent colors to transfer. Keep fluorescent surfaces dry and avoid contact with other materials.
• Rubbing surfaces with fluorescent paint against other surfaces can transfer the paint.

CASIO COMPUTER CO., LTD. is not responsible for any damage that may occur from the use of this watch and accepts no claims from third parties.

Thermo Scanner Mode

Use the built-in sensor to measure the temperature of an object by bringing it close to the watch. Readings are approximate and not for precise measurements. It measures surface temperature only. Be cautious with hot objects.

Using the Thermo Scanner

1. Bring the object close to the watch's sensor, located on the upper right side.
2. Enter Thermo Scanner Mode and press "D" to start temperature measurement.
3. The sensor calculates temperature based on infrared radiation emitted by the object, which depends on the object's temperature, material, and surface properties (emissivity). The default emissivity is 0.95, but it can be adjusted for more accurate readings.

Checking Emissivity

In Thermo Scanner Mode, press "B" to display the emissivity value.

Changing Emissivity

1. In Thermo Scanner Mode, press "A" to start settings.
2. Use "D" and "B" to adjust the value. The range is 0.10 to 1.20, with increments of 0.05.
3. Pressing "D" and "B" simultaneously resets the value to the default 0.95.
4. Press "A" to exit.

Changing Temperature Units

1. In Thermo Scanner Mode, press "A" to start settings.
2. Press "C" to select the unit mode (°C or °F).
3. Press "D" to select the desired unit.
4. Press "A" to exit.

Troubleshooting

• "Err. NO 1": Temperature out of operating range (-20°C to 60°C). Avoid direct sunlight or extreme temperatures.
• "Err. NO 2": Measured temperature out of range (-20°C to 200°C).
• "Err. NO 3": Rapid temperature change. Wait approximately 10 minutes for the temperature to stabilize.
• "Err. NO 4": Sensor error. Stop temperature measurement (return to Timekeeping Mode by pressing "C") and retry.
• "Err. NO 5": Low battery power or very low temperature. Replace the battery. The watch will resume normal operation when the temperature returns to normal.
• "E": Check the emissivity setting. If it hasn't been changed, continue measurements.
