Precautions

B.3.1 Handset
• Avoid volume levels that may be harmful to your hearing. Exposure to excessive sound pressure from a
handset's earpiece, or headset, may cause permanent hearing loss.
• Low volume levels might result in missed alerts.
• Only use the handset in temperatures between: -5 °C and +45 °C (23 °F and 113 °F).
• Avoid exposing the handset to direct sunlight, heat sources, or moisture.
• Do not place a cold handset in a charger.
• Avoid sudden temperature changes to prevent condensation in the handset.
• It's recommended to put the handset in an air tight plastic bag until the temperature is adjusted, for
example, when entering, or leaving, a cold/heated building on a warm/cold day.
• If the handset has been exposed to water, or condense, remove the battery immediately and let it dry
completely before reinserting the battery.
• Do not expose the handset to an open flame.
• Protect your handset from aggressive liquids and vapors.
• Remove the handset from the charger before cleaning the handset to reduce risk of an electric shock.
