Maintenance
1. Water Resistance (IP68)
The Coucur Y66 Smartwatch is IP68 water-resistant, meaning it is protected against dust ingress and can withstand immersion in water up to 1.5 meters for up to 30 minutes. It is suitable for daily use, hand washing, and light rain. Avoid hot water, saunas, or diving, as steam and high pressure can compromise the seal.
2. Cleaning
Regularly clean your smartwatch and strap with a soft, dry cloth. If necessary, use a slightly damp cloth with mild soap, then wipe dry. Avoid harsh chemicals or abrasive materials.
3. Battery Care
To prolong battery life, avoid fully discharging the watch frequently. Charge the device when the battery level is low. Store the watch in a cool, dry place if not used for extended periods.
