PRECAUTIONS
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 and moisture.
• Do not place a cold handset in a charger.
• Avoid sudden temperature changes to prevent condensation in the handset. It is recom-
mended to put the handset into 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 re-inserting the battery.
• Do not expose the handset to open flame.
• Protect your handset from aggressive liquids and vapors.
• Remove the handset from the Charger before cleaning the handset to reduce risk of 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 is 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 Desktop Charger, the Charging Rack, or the Battery Pack Charger for charging.
Charge the battery for at least one hour the first time you use the battery.
