• Avoid liquids, including water. Liquids can get into your watch circuits, leading to corrosion.
• Keep your watch away from heat sources. High temperatures can cause the battery to swell, leak,
or malfunction.
• Always keep the mini-USB cover closed when not in use to help keep water from getting in.
• If your watch gets wet, don’t attempt to dry it with any heat source, such as a hair dryer or
microwave oven. Allow it to dry naturally at room temperature.
• Don’t leave your watch in your car. High temperatures may cause malfunction.
• Avoid dropping your watch. Dropping it can potentially cause damage.
• Contact a MARTIAN WATCHES representative if your watch or its battery has been damaged
due to a drop, liquid exposure or high temperatures.
Warning: Use of an unauthorized battery may present a risk of explosion, fire, leakage, or other
hazard.
Disposal: Dispose of your watch in accordance with local regulations for used batteries. Contact
your local recycling center or national recycling organizations for more information on how to
dispose of batteries.
Warning: Never dispose of batteries in a fire because they may explode.
Battery Charging:
Notes for charging your watch battery:
• During charging, keep your watch and charging cable at room temperature for efficient battery
charging.
• When you receive your watch, the battery is not fully charged.
• MARTIAN WATCHES have circuitry that protects the battery from damage from overcharging;
however, for longest life, remove your watch from the charging cable as soon as the battery
indicator shows “full”.
Potentially Explosive Atmospheres:
Areas with potentially explosive atmospheres are often, but not always, posted and can include
fueling areas, such as below decks on boats, fuel or chemical transfer or storage facilities, or
areas where the air contains chemicals or particles, such as grain dust, or metal powders. When in
such an area, turn off your watch and do not remove the back cover. In such areas, sparks can
occur and cause an explosion or fire.
Children:
Keep your watch away from small children. The watch is not a toy and may be hazardous to small
children. For example:
• A choking hazard may exist for small, detachable parts such as the USB cover.
• Improper use could result in loud sounds, possibly causing hearing injury.
