1.3. WATER RESISTANCE
Suunto X10 is water resistant. Its water resistance is tested to 100m/330ft according to
ISO 2281 standard (www.iso.ch). This means that you can use the Suunto X10 for
swimming or other water sports activities but it should not be used for scuba diving or
freediving.
NOTE: Do not push the buttons under any circumstances while swimming or in
contact with water. Deliberate or unintentional depression of the buttons while the unit
is submerged could cause the unit to malfunction.
NOTE: Large amounts of water and dirt under the cover of Suunto X10 may disturb
the satellite signal reception.
1.4. CHARGING THE BATTERY
Suunto X10 is equipped with an internal rechargeable battery. You can recharge the
battery approximately 500 times. The life expectancy of a single charge can range
from 6 hours (with heavy usage of the GPS, backlight, compass and data storage
functions) to over 2 months if you only use Time and/or Alti/Baro mode.
When the battery level indicator on the display reaches the red zone, the battery
voltage is low and you should recharge the battery.
Do not attempt to replace the battery, as this will void warranty. Take your Suunto X10
to an authorized Suunto dealer for a battery replacement.
You can charge the battery with the included mains charger (universal mains voltage),
through your PC’s USB connector.
WARNING: This Suunto product contains a Li-ion battery. To reduce the risk of fire or
burns, do not disassemble, crush, puncture, short external contacts or dispose of in
fire or water. The battery should only be replaced by Suunto Service. Recycle or
dispose of used batteries properly.
