The C781 is water resistant. It provides reliable performance for outdoor activities, and
in wet conditions such as driving rain or high humidity.
The tested devices meets the requirements of the MIL-STD-810G (Rain & immersion
1m, 30min) standard.

To maintain water resistance:
• Securely close the Charging/Data Port cover and the Headset Jack cover.

ShOCk RESISTANCE
The rugged construction of the Ravine™ provides outstanding shock and vibration
resistance. The tested device meets the requirements of the MIL-STD-810G (Drop 1.5m)
standard.
CAUTION:
The shock and vibration resistance features do not guarantee protection
against every type of shock and vibration. Your handset may be damaged or
malfunction depending on the severity of the shock or vibration.
DUST RESISTANCE
For additional peace of mind, the Ravine™ is also dust resistant. The device was tested
using silica flour at a temperature of 95°F and meets the MIL-STD-810 (Dust) standard.
• Your handset can be rinsed with clean water when dirty. To ensure water resistance,
make sure that all covers are securely closed before rinsing.
• Periodically, clean the Charging Terminals and Battery Terminals with a dry cloth
or cotton swab. Dust may cause electrical connection problems. Avoid wiping with
excessive force, which can damage the terminals.
