Safety Information

This is a Class 1 laser device.

Warning: Use fiber optic ports only for data communications applications that

require optical fiber. Use only with the appropriate connector. When not in use,

replace dust cover. Using this module in ways other than those described in this

manual can result in intense heat that can cause fire, property damage, or

personal injury.

Lithium Battery

The battery in the bq4830/DS1644 device is encapsulated and not user-replaceable. The

battery is located on the SMMi for the Alpine switch, and the MSM motherboard for the

BlackDiamond switch.

If service personnel disregard the instructions and attempt to replace the

bq4830/DS1644, replace the lithium battery with the same or equivalent type, as

recommended by the manufacturer.

Warning: Danger of explosion if battery is incorrectly replaced. Replace only with

the same or equivalent type recommended by the manufacturer. Dispose of used

batteries according to the manufacturer’s instructions.

• Disposal requirements vary by country and by state.

• Lithium batteries are not listed by the Environmental Protection Agency (EPA) as a

hazardous waste. Therefore, they can typically be disposed of as normal waste.

• If you are disposing of large quantities, contact a local waste-management service.

• No hazardous compounds are used within the battery module.

• The weight of the lithium contained in each coin cell is approximately 0.035 grams.

• Two types of batteries are used interchangeably:

— CR chemistry uses manganese dioxide as the cathode material.

— BR chemistry uses poly-carbonmonofluoride as the cathode material.
