2.1. Battery Installation/Replacement

The NORTH EDGE Apache watch uses a CR2032 coin cell battery. When the battery is low, the watch may display a low power indicator. To replace the battery:

1. Carefully remove the four screws on the back cover of the watch using a small Phillips head screwdriver.
2. Gently lift the back cover to expose the battery compartment.
3. Remove the old CR2032 battery and insert a new one, ensuring the positive (+) side faces upwards.
4. Replace the back cover, aligning it properly, and secure it with the four screws. Ensure the gasket is correctly seated to maintain water resistance.

4. Maintenance

4.1. Water Resistance

The NORTH EDGE Apache watch is water resistant up to 50 meters (5 ATM). This makes it suitable for general swimming in shallow water. However, to maintain its water resistance, please observe the following:

• Do not press any buttons while the watch is submerged in water.
• Avoid exposure to hot water or steam (e.g., hot showers, saunas, hot tubs), as this can compromise the seals.
• The watch is not suitable for long-duration underwater activities such as diving or snorkeling.
• After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.

4.2. Cleaning

Clean the watch case and strap regularly with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used. Avoid harsh chemicals or abrasive materials that could damage the watch's finish or strap.

4.3. Strap Care

The durable nylon strap can be cleaned with mild soap and water. Allow it to air dry completely before wearing. Avoid prolonged exposure to direct sunlight or extreme temperatures, which can degrade the material.
