Setup
Initial Time Setting and Time Zone
Upon first use or after a battery change, you may need to set your home city (time zone) manually. This is crucial for the watch to receive the correct time calibration signal.
- In Timekeeping Mode, press and hold the ADJUST button (usually top-left) until the city code starts to flash.
- Use the FORWARD and REVERSE buttons (usually on the right side) to select your desired home city code. Refer to the world time map for city codes corresponding to your region.
- Press the MODE button (usually bottom-left) to cycle through other settings like DST (Daylight Saving Time) and 12/24-hour format. Adjust these as needed using the FORWARD and REVERSE buttons.
- Press the ADJUST button again to exit the setting screen.
Radio Signal Reception (Wave Ceptor)
Your watch automatically receives time calibration signals to maintain accurate time. Automatic reception typically occurs in the early hours of the morning. For best reception, place the watch near a window overnight.
To manually initiate signal reception:
- In Timekeeping Mode, press and hold the RECEIVE button (refer to watch diagram for exact button, often bottom-right) for about two seconds.
- The watch will display "RCV" or "GET" to indicate it is attempting to receive the signal.
- Keep the watch stationary and away from sources of interference (e.g., computers, televisions) during reception.
- Successful reception will be indicated by "OK" or "RCVD". If reception fails, "ERR" or "FAIL" will be displayed.

Maintenance
Battery Replacement
The watch is powered by a Lithium metal battery. When the display becomes dim or functions become unreliable, it is time to replace the battery. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and water resistance.
Water Resistance (50 Meters / 5 Bar)
Your watch is water resistant to 50 meters (5 bar). This means it is suitable for everyday use and can withstand splashes, rain, showering, and shallow swimming. It is not suitable for diving, snorkeling, or high-impact water sports. Do not operate buttons while the watch is wet or submerged.
Cleaning
Wipe the watch case and strap with a soft, dry cloth. For resin straps, you can use a mild soap solution and rinse thoroughly, then dry completely. Avoid using harsh chemicals or abrasive cleaners.
Troubleshooting
