Setup
1. Initial Charging (Tough Solar)
Your watch is powered by a solar cell and a rechargeable battery. Ensure the watch is exposed to light regularly to maintain a sufficient charge. Place the watch in a location where it can receive direct sunlight or strong artificial light. Avoid covering the watch face.
2. Time Setting (Atomic Timekeeping)
The PRG600-1CR is equipped with Atomic Timekeeping, which automatically receives time calibration signals. For optimal reception, place the watch near a window at night. If automatic reception is not possible, you can set the time manually.
- Manual Time Adjustment: Refer to the detailed instructions in the full module manual (Module 5497) for specific steps on manual time and date setting using the crown and buttons.
- Home City Setting: Ensure your Home City is correctly set for accurate World Time and signal reception.
3. Sensor Calibration
For accurate readings, calibrate the sensors periodically, especially after significant changes in environment or location.
- Compass Calibration: Perform a figure-eight motion with the watch to calibrate the magnetic sensor.
- Altimeter Calibration: Calibrate the altimeter using a known altitude reference point.
- Barometer Calibration: Calibrate the barometer using a known atmospheric pressure value.
- Thermometer: For accurate temperature readings, remove the watch from your wrist for at least 20-30 minutes to avoid body heat interference.
Operating Modes
The watch features multiple modes accessible via the mode button, typically located on the left side of the watch case.
1. Timekeeping Mode
Displays the current time, date, and day of the week. This is the default mode.
2. Compass Mode
To activate the compass, press the dedicated compass button (often labeled 'COMP'). The second hand will indicate North, and the digital display will show the direction and bearing angle.
3. Altimeter Mode
Press the altimeter button (often labeled 'ALTI') to display the current altitude. The watch measures atmospheric pressure to calculate altitude. Readings can be affected by weather changes.
4. Barometer/Thermometer Mode
Press the barometer button (often labeled 'BARO') to display atmospheric pressure and temperature. The digital display will show the current barometric pressure and temperature. Remember to remove the watch from your wrist for accurate temperature readings.
5. Stopwatch Mode
To use the stopwatch:
- Navigate to Stopwatch Mode using the mode button.
- Press the start/stop button to begin and end timing.
- Press the reset button to clear the stopwatch.
6. Countdown Timer Mode
To set and use the countdown timer:
- Navigate to Countdown Timer Mode.
- Use the adjustment buttons to set the desired countdown time.
- Press the start/stop button to begin the countdown. An alarm will sound when the timer reaches zero.
7. World Time Mode
Displays the current time in various time zones around the world. Rotate the crown or use specific buttons to cycle through different city codes.
8. Alarm Mode
The watch supports multiple daily alarms. To set an alarm:
- Navigate to Alarm Mode.
- Select an alarm number.
- Use the adjustment buttons to set the alarm time.
- Enable or disable the alarm as needed.
Maintenance
1. Cleaning
Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner or benzine.
2. Water Resistance
The PRG600-1CR is water resistant to 100 meters. This means it is suitable for swimming and snorkeling. Do not operate buttons or the crown while the watch is wet or submerged. Ensure the screw lock crown is securely tightened before exposure to water.
3. Tough Solar Battery Care
To ensure stable operation, expose the watch to light frequently. Avoid storing the watch in a dark place for extended periods, as this can deplete the rechargeable battery. If the charge level becomes low, functions may be disabled or the timekeeping may become inaccurate.
Troubleshooting
- Inaccurate Sensor Readings: Recalibrate the compass, altimeter, or barometer as described in the Setup section. Ensure the thermometer is not affected by body heat.
- Time Discrepancies: Verify that your Home City setting is correct. Ensure the watch is receiving atomic time calibration signals. If not, perform a manual time adjustment.
- Low Power Indicator: If the digital display shows a low power indicator (e.g., 'CHG' or 'LOW'), expose the watch to strong light for several hours to recharge the battery.
- Buttons Not Responding: Check if the watch is in a special mode that locks buttons, or if the battery charge is extremely low.
For persistent issues, consult the full module manual (Module 5497) or contact Casio customer support.
