Precautions and Environmental Requirements
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:
-20 °C and +40 °C (-4 °F and 104 °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 in such a
way that the battery has come into contact with the 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.
• Keep the handset away from strong electromagnetic fields.
• The handset may retain small metal objects around the earpiece
region.
• Do not place heavy objects on the handset.
• Do not allow children to play with the product packaging material.
This could cause choking and/or suffocation.
• Do not allow children to play with the handset. It's not a toy.
Battery
• Do not immerse the battery into water. This could short-circuit and
damage the battery.
• Do not expose the battery to an open flame. This could cause the
battery to explode.
• Do not allow the metal contacts on the battery to touch another
metal object. This could short-circuit and damage the battery.
• Do not leave the battery where it could be subjected to extremely
high temperatures, such as inside a car on a hot day.
• Use the Micro-USB cable of v.2.0 or higher (together with the USB
power supply), the desktop charger, the rack charger, or the
battery pack charger for charging. Charge the battery for at least
one hour the first time you use the battery.
• Do not charge the battery when the ambient room temperature is
above 40 °C or below 5 °C (above 104 °F or below 41 °F).
• Do not attempt to take the battery apart.
• Do not remove the battery unless it needs to be replaced.
• Turn off the handset before removing the battery (recommended).
• Defective batteries must be returned to a collection point for
chemical waste disposal.
