Important Notes about Chargers and Battery Packs
• Chargers operate in a 50° to 85° F (10° to 30° C) environment. Do not expose
them to freezing temperatures or direct sunlight.
• Do not place anything in the charger other than the endpoint. You might damage
the contacts. Bent contacts can keep the endpoint from charging.
• It is normal for the battery pack to become warm when charging.
• Only use Inter-Tel battery packs with Inter-Tel chargers.
• Never use non-Inter-Tel charging units as they could damage the battery pack.
• Only use the original plug-in power adapter for the chargers.
• Do not dip the battery pack in water or throw into fire.
• Do not throw away the battery pack with your domestic waste. Take used battery
packs to an appropriate collection point for recycling or send them back to your
supplier or servicing agent.
Replacement battery packs are available from your supplier or servicing agent.
