Battery Guidelines
• Never tamper with or dismantle the battery pack.
• Avoid touching the battery contacts.
• If necessary, clean the contacts with a damp cloth.
• Protect the battery contacts from contact with any metal objects.
• Never immerse batteries in water or throw them into a fire.
When setting up the phone:
• Use only the rechargeable batteries supplied with this product.
• Follow the battery installation instructions included with this guide.
• Charge the batteries using only the charger stand supplied with this product.
Note: That it takes two to three charging cycles for the batteries to reach their fully charged state.
During operation:
• It is normal for the batteries to become warm when charging.
• Discharge the batteries from time to time to prolong their service life.
To do this, do not place the phone back into the charger stand until the
batteries are completely or almost completely discharged. The battery icon
on the display indicates when the batteries are low and an alert tone is
sounded every three minutes.
• Only use batteries and charging units approved by the manufacturer.
• If you do not intend to use the phone for an extended period, the batteries
should be removed from the handset.
• Store batteries at room temperature. Above average temperatures tend to
reduce the service life of batteries.
• Do not throw away or incinerate used batteries. Take them to an
appropriate collection point for recycling or send them back to your supplier
or distributor.
Note: The batteries included with the 9480i CT handset are designed to provide up to four
hours talk time and ninety six hours standby time. Actual battery performance can be
affected by a wide variety of environmental and user factors
