! WARNING

LITHIUM BATTERY CHEMICAL HAZARD

Do not use a device with a damaged battery. Using a damaged battery may further

damage the device, cause it to fail, or in hazardous locations cause other

unintended consequences.

Lithium batteries are volatile. When handling and storing lithium metal batteries, follow these

precautions:

• Store and handle lithium metal batteries to avoid contact with other lithium batteries.

• Do not place lithium metal batteries on metal work surfaces.

• Avoid exposing lithium metal batteries to extreme temperatures.

• If you store an inactive device, remove the battery.

• Dispose of used or defective batteries in accordance with the applicable statutes and regulations, as

well as site-specific safety requirements.

The lithium batteries will typically last up to five years. Use the Ranger Pro software or your network

vendor's application to monitor battery performance and replace batteries as needed.
