Operation Guide 5242

Specifications

Accuracy at normal temperature: ± 15 seconds a month (with no signal calibration)

Timekeeping: Hour, minutes (hand moves every 10 seconds), seconds, day, day of the week Calendar system: Full Auto-calendar pre-programmed from the year 2000 to 2099

Other: Home City code (can be assigned one of 29 city codes and Coordinated Universal Time); Daylight Saving Time (summer time) / Standard Time

Time Calibration Signal Reception: Auto receive up to six times a day (5 times a day for the Chinese calibration signal; Remaining auto receives cancelled as soon as one is successful); Manual receive

Receivable Time Calibration Signals:

Mainflingen, Germany (Call Sign: DCF77, Frequency: 77.5 kHz); Anthorn, England (Call Sign:

MSF, Frequency: 60.0 kHz); Fukushima, Japan (Call Sign: JJY, Frequency: 40.0 kHz); Fukuoka/

Saga, Japan (Call Sign: JJY, Frequency: 60.0 kHz); Fort Collins, Colorado, the United States

(Call Sign: WWVB, Frequency: 60.0 kHz); Shangqiu City, Henan Province, China (Call Sign:

BPC, Frequency: 68.5 kHz)

Compass: 20 seconds continuous reading; North indication by hand; Calibration (bidirectional, northerly); Manual reading

Altimeter:

Measurement range: –700 to 10,000 m (or –2,280 to 32,800 ft.) without reference altitude

Display range: –3,000 to 10,000m (or –9,840 to 32,800 ft.)

Negative values can be caused by readings produced based on a reference altitude or due to atmospheric conditions.

Measurement unit: 10 m (or 40 ft.)

Other: Calibration; Manual reading

E-80

Barometer:

Measurement range: 260 to 1,100 hPa (or 7.7 to 32.5 inHg)

Display unit: 1 hPa (or 0.1 inHg)

Other: Calibration; Manual reading; Barometric pressure differential indicator

Thermometer:

Measurement range: –10.0 to 60°C (or 14 to 140°F)

Measurement unit: 0.1°C (or 1°F)

Other: Calibration; Manual reading

Bearing Sensor Precision:

Direction: Within ±12°

Values are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).

•Values are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).

•Precision is lessened by strong impact to either the watch or the sensor, and by temperature extremes.

Temperature Sensor Precision:

±2°C (±3.6°F) in range of –10°C to 60°C (14°F to 140°F) Alarm: Daily alarm

Stopwatch:

Measuring unit: 1 second

Measuring capacity: 11:59' 59"

Measuring modes: Elapsed time

Illumination: LED (light-emitting diode); Selectable illumination duration; Auto Light Switch (Full Auto LED Light operates only in the dark)

Other: Power Saving function; Low battery alert (second hand jumping at 2-second intervals); Auto hand position adjustment

Power Supply: Solar panel and one rechargeable battery

Approximate battery operating time: 7 months (from full charge to Level 3) under the following conditions:

Alarm: 10 seconds/day

Light: 1.5 seconds (one operation)/day

Second hand operation: 18 hours/day

Time calibration receive: 4 minutes/day

Direction reading: 20 times/month (20 seconds continuous reading)

Readings using the barometric pressure differential indicator: 12 times/day

Climbs: Once (30 altituded readings)/month

Frequent use of illumination runs down the battery. Particular care is required when using the auto light switch (page E-71).
