This document provides instructions and information for operating the Casio MRT-200 digital watch, module 2413.
Important Information
Battery
The battery is installed at the factory and should be replaced by an authorized CASIO dealer or distributor when it shows signs of weakness (e.g., backlight not turning on, dim display).
Water Resistance
Your watch is classified by its water resistance rating (Levels I to V). Refer to the table below for proper usage.
| Rating | Marking on Case | Splash, Rain, Washing | Swimming, Machine Washing | Diving | Scuba Diving |
|---|---|---|---|---|---|
| I | WATER RESISTANT | Yes | No | No | No |
| II | 50M WATER RESISTANT | Yes | Yes | No | No |
| III | 100M WATER RESISTANT | Yes | Yes | Yes | No |
| IV | 200M WATER RESISTANT | Yes | Yes | Yes | Yes |
| V | 300M WATER RESISTANT | Yes | Yes | Yes | Yes |
Notes for respective ratings:
- I: Watch is not water resistant. Avoid all moisture.
- II: Do not pull out the crown [⚙️] while the watch is wet. Do not press buttons [▶️] underwater.
- III: If exposed to salt water, rinse thoroughly and dry.
- V: Suitable for scuba diving (excluding depths requiring a helium-oxygen mixture).
Watches with leather straps are not suitable for swimming or activities where the strap will be submerged.
Care for Your Watch
- Replace the gasket every 2-3 years for water and dust resistance.
- If water enters the watch, have it checked by a CASIO dealer.
- Avoid extreme temperatures.
- Handle with care; avoid dropping [⬇️].
- Do not wear the band too tightly; allow a finger's width between the band and your wrist.
- Clean with a dry soft cloth or a soft cloth dampened with a mild detergent solution. Avoid volatile agents (e.g., benzine, solvents).
- Store in a dry place when not in use.
- Avoid contact with benzine, solvents, aerosols, adhesives, paint, etc., as these can damage gaskets, case, and finish.
- Be careful when cleaning silk-screened designs on bands to avoid damage.
For Watches with Plastic Bands
- White powdery substance on the band is harmless and can be wiped off.
- Sweat or moisture, or high humidity can cause damage or cracking. Wipe clean regularly.
For Watches with Fluorescent Cases and Bands
- Prolonged direct sunlight can cause fluorescent colors to fade.
- Moisture can cause fluorescent colors to fade. Wipe off moisture immediately.
- Contact with other wet surfaces can cause fading. Keep fluorescent surfaces dry.
- Rubbing can transfer fluorescent color.

General Description of Operating Modes
Pressing button "C" [C] cycles through modes in the following order: Timekeeping Mode ➡️ Barometer Mode ➡️ Altimeter Mode ➡️ Dive Mode ➡️ Alarm Mode ➡️ Stopwatch Mode ➡️ Timekeeping Mode.
Pressing button "B" [B] in any mode (except Stopwatch) activates the backlight [?] for 2 seconds.
Diagram Description: An illustration shows the watch face with labels for different modes: Timekeeping Mode, Barometer Mode, Altimeter Mode, Depth Gauge Mode, Alarm Mode. Buttons A, B, C, D are indicated.
Timekeeping Mode
Press button "D" [D] to switch between display views: time and date, or time and pressure graph.
Diagram Description: Shows Time and Date screen (with Day of the week, Month-Day) and Time and Pressure Graph screen. Also shows PM indicator, Seconds, Hour:Minutes.
Setting the Time and Date
- Press button "A" [A] in Timekeeping Mode. Seconds will flash.
- Press button "C" [C] to select values to adjust in this order: Seconds ➡️ Hours ➡️ Minutes ➡️ Year ➡️ Month ➡️ Day.
- Press button "D" [D] to increase the selected value. Holding "D" [D] increases the value faster.
- Press button "D" [D] to reset seconds to 00. If seconds are 30-59, minutes will increment.
- Press button "B" [B] to switch between 12-hour and 24-hour time formats.
- Press button "A" [A] to return to Timekeeping Mode. The watch will automatically return to Timekeeping Mode if no buttons are pressed for a while.
Backlight
Pressing button "B" [B] activates the electro-luminescent (EL) backlight [?] for 2 seconds.
- The EL backlight's brightness may decrease over time.
- A faint sound may be heard when the backlight is on; this is normal.
- Backlight is difficult to see in direct sunlight.
- Frequent use of the backlight shortens battery life.
Barometer Mode
The watch has a built-in atmospheric pressure sensor, factory calibrated.
Atmospheric Pressure Monitoring (in Timekeeping Mode)
Pressure readings are automatically recorded every 3 hours (starting from noon) and displayed as a graph of pressure changes over the last 18 hours. A flashing cursor indicates the latest data.
Diagram Description: Shows a graphic indicator with hourly segments (3am to 9pm) and arrows indicating pressure change (Up ⬆️, No change ↔️, Down ⬇️). Also shows the Barometric Pressure Graph.
Measurements are taken every 9, 6, and 3 seconds, then averaged.
Press button "D" [D] in Timekeeping Mode to view the pressure graph.
Barometer Mode Operation
- Press button "C" [C] to enter Barometer Mode. The current atmospheric pressure is displayed.
- The display is graduated in 1 hPa increments (or 0.05 in.Hg).
- Press button "D" [D] to stop measurement and start a new one.
- Some regions use millibars (mb) instead of hectopascals (hPa); 1 hPa = 1 mb.
Barometer Graphical Indicator
The graphical indicator shows current atmospheric pressure by filling segments from left (low pressure) to right (high pressure).
Diagram Description: Shows pressure change indicators for different hPa/mb ranges (e.g., "more than 11hPa/mb down ⬇️", "4-5hPa/mb up ⬆️"). Also shows a graphic indicator with filled segments representing pressure.
Note: Sudden pressure changes may cause the graph to shift out of view. Readings resume when pressure normalizes.
Measurement saving may be skipped if:
- Sensor malfunction ([ERROR] indicator).
- Low battery ([BATT] indicator).
- Pressure exceeds sensor range ([FULL] indicator).
Diagram Description: A graph showing atmospheric pressure changes over time (Noon, 3pm, 6pm).

- Press button "C" [C] to switch between hPa and in.Hg.
- Press button "A" [A] to return to Barometer Mode.
Sensor Calibration
- In Barometer Mode, press and hold button "A" [A] until the pressure value flashes.
- Use button "D" [D] to increase or "B" [B] to decrease the value.
- Pressing "B" [B] and "D" [D] simultaneously resets to factory settings.
- Press "A" [A] to save and return to Barometer Mode.
Altimeter Mode
The altimeter uses the pressure sensor to calculate altitude based on International Standard Atmosphere. Altitude can be displayed in meters (m) or feet (ft).
Note: Altitude readings are approximate and should not be used for critical measurements. Factors like temperature changes can affect accuracy.
Setting a Reference Altitude
The altimeter measures relative altitude. You can set an absolute altitude or a zero reference.
Setting an Absolute Altitude Value

- Press "A" [A] to finish.
Setting a Zero Altitude Value
This sets the current location as zero altitude for relative measurements (e.g., at the base of a mountain).
- In Altimeter Mode, press button "A" [A].
- Press buttons "B" [B] and "D" [D] simultaneously to set zero altitude.
- Press "A" [A] to finish.
Tracking Altitude Readings
Upon entering Altimeter Mode, altitude tracking begins automatically. Readings are taken every 3 seconds for the first 5 minutes, then every minute. Press "D" [D] to stop and start a new measurement.
Diagram Description: Shows the Altimeter Mode screen with Altitude indicator, Mode indicator, and Timekeeping Mode indicator. Also shows a graphic indicator representing altitude.
The "FULL" indicator [FULL] appears if altitude readings exceed the sensor's range (-4000m to +4000m or -13120ft to +13120ft).
The graphical indicator shows altitude by filling segments from left (low) to right (high).
Diagram Description: Shows altitude change indicators for different meter/foot ranges.

- Measurement increments: 0.1 meter (1 foot).
- Depth readings are 0 up to 1 meter (3 feet).
- "FULL" indicator [FULL] appears above 30 meters (99 feet).
The graphical indicator shows depth. Segments fill from left to right as depth increases.
Diagram Description: Shows the Dive Mode screen with Depth indicator, Mode indicator, and Timekeeping Mode indicator. Also shows a graphic indicator representing depth.
You cannot exit Dive Mode or change settings while diving to prevent accidental changes.
