CASIO PRG-240-1ER

Specifications

ILLUMINATION
- EL backlight (electroluminescent panel); selectable illumination duration (approximately 1 second or 3 seconds).
- Fully automatic illuminator. When this function is active, simply turn the wrist slightly to illuminate the back of the watch. Energy saving: the fully automatic illuminator only works in the dark.

DUPLEX LCD
- To keep an eye on everything: the display elements are chromatically distinguishable from each other. This is made possible by the use of different coloured layers, placed one on top of the other, which represent the information more clearly.

SOLAR POWER SUPPLY
- The power supply of the watch is provided by independent, environmentally friendly solar cells. Surplus solar energy is stored in a battery.

LOW TEMPERATURE RESISTANCE (-10ºC/14ºF)
- The watch withstands temperatures as low as -10 °C.

WORLD TIME
- 48 cities (31 time zones).
- Daylight saving time/standard time.

DIGITAL COMPASS
- 20 seconds continuous measurement; 16 directions; angle value 0° to 359°; four-way pointers; calibration (bi-directional, north); magnetic declination correction;

orientation memory.

ORIENTATION SENSOR ACCURACY
- Direction: Within ±10°.
- Values are guaranteed for a temperature range of -10°C to 40°C (14°F to 104°F).
- North Pointer: Within ±2 digital segments.

BAROMETER
- Measuring Range: 260 hPA to 1,100 hPA (7.65 in. Hg to 32.45 in. Hg).
- Display unit: 1 hPA (0.05 in. Hg).
- Measurement time: Daily from midnight, at hourly intervals (12 times per day), every five seconds in barometer/thermometer mode.
- Calibration, manual measurement (push button operation).
- Barometric pressure graph, barometric pressure difference pointer.

ALTIMETER
- Measuring range: -700 m. to 10,000 m. (-2,300 ft. to 32,800 ft.) without reference altitude.
- Display range: -10,000 to 10,000 m. (-32,800 to 32,800 ft.). Readings produced based on a reference altitude or due to atmospheric conditions may result in negative values.
- Display unit: 5 m (20 ft).
- Current altitude data: 5-second intervals for 1 (SHORT) or five-second intervals for the first three minutes followed by 2-minute intervals for the subsequent 9 or 10 hours (LONG).
- Altitude memory data:
- 40 periodic records: readings taken at start of measurement, end of measurement and minutes 00, 15, 30 and 45 of each hour.
- A current session log: Readings taken at 5 second intervals per hour (0`05), or at 5 second intervals for the first 3 minutes followed by 2 minute intervals for the next 9 or 10 hours (2`00) and used to update values for high altitude, low altitude, total ascent and total descent.
- A history log: Keeps track of high altitude, low altitude, total ascent, total descent values for multiple sessions.
- Others: Reference altitude setting, altitude graph; 4 display formats; altitude difference; altitude measurement type (0`05 or `2`00).

THERMOMETER
- Measuring range: -10ºC to 60ºC (-14ºF to 140ºF).
- Display unit: 0.1ºC (0.2ºF).
- Measuring time: Every five seconds in barometer/thermometer mode.
- Calibration, manual measurement (push button operation).

TEMPERATURE SENSOR ACCURACY
- +/- 2ºC (+/- 3.6ºF) in the range of -10ºC to 60ºC (14ºF to 140ºF).

SUNRISE AND SUNSET INDICATOR
- After entering the geographical position, the sunrise and sunset times for any date can be displayed.
- Sunrise and sunset times for a specific date, daylight pointers.

STOPWATCH
- Measuring unit: 1/100th of a second.
- Measurement capability: 23:59'59.99".
- Measuring mode: Elapsed time, split time, 1st and 2nd arrival times.

COUNTDOWN TIMER
- For all those who demand precision: countdown timers are very useful when it comes to remembering special or periodic events, as they emit an acoustic signal at the programmed time. They can be set by the minute or up to 24 hours in advance. Particularly practical for daily medication or interval training.
- Measuring unit: 1 second.
- Countdown start time setting range: 1 minute to 24 hours (1 minute increments and 1 hour increments).

ALARMS
- The daily alarm will remind you of recurring daily appointments by an acoustic signal sounding at the set time. This model is equipped with 5 independent alarms to remind you of important appointments.

TIME SIGNAL

LOW BATTERY INDICATOR
- An indicator shows the current battery level.

ENERGY SAVING FUNCTION

REGULAR TIME
· Hours, minutes, seconds, PM (P), year, month, date and day of the week.

12/24 HOUR FORMAT
· Hours are displayed in either 12 or 24 hour format.

AUTOMATIC CALENDAR
· Once set, the automatic calendar always shows the correct date. Fully automatic calendar pre-programmed from the year 2000 to 2099.

CLOCK ACCURACY
· +/- 15 Seconds at normal temperature.

BUTTON SOUND ON/OFF
· If desired, it is possible to disable the button sound with the Mode button. Once disabled, the watch will stop beeping when changing from one function to another. Set alarms or countdown timer are still active after you turn off the button sound.

TIME INDICATION
· Hour, minutes, seconds, p.m. (P), year, month, day, day of the week.

BATTERY LIFE
· Solar cell and a rechargeable battery. Approximate battery life: 6 months (from full charge to level 4) under the following conditions:
· The watch is not exposed to light.
· Internal timekeeping.
· Presentation activated 18 hours per day, torpor condition 6 hours per day.
· 1 backlight operation per day (1.5 seconds).
· 10 seconds of alarm operation per day.
· 10 digital compass operations per week.
· 1 hour of altimeter measurement at intervals of 5 seconds, once a month.

RESIN BOX

ROTATING STEERING BEZEL
· This rotating bezel can be used to determine the current time in other cities around the world.

MINERAL GLASS
· Hard, scratch-resistant mineral glass protects the watch from external damage.

RESIN STRAP
· The strap contains synthetic resin, an ideal material for this component given its extreme strength and flexibility.

WATER RESISTANCE CLASSIFICATION (10BAR)
· Perfect for swimming and diving: the watch is water resistant to 10 bar / 100 meters. This indication of meters does not refer to the depth of immersion, but to the air pressure that has been used in the waterproof test. (ISO22810).
