Accessory Guidelines

Follow these guidelines when using accessories with your Cisco Wireless IP Phone 882x Series:

- Use only chargers, batteries, and accessories that are approved by the phone manufacturer. Use of unapproved chargers, batteries, and accessories might be dangerous, and invalidates the warranty on your phone.

- Do not adhere a clip to the back of the phone or insert a clip between the phone and battery cover because it can damage the battery.

- When disconnecting the power cord of any accessory, grasp and pull the plug. Do not pull the cord.

- Keep accessories out of the reach of young children.

- Clean the phone with a soft, dry cloth or a moist wipe.

- The phone is resistant to dust and spills, but you can further protect your phone with a cover case.

Note

The Cisco Wireless IP Phone 8821-EX has not been tested for wired and Bluetooth headsets in hazardous locations.

- Important Headset Safety Information

Important Headset Safety Information

High Sound Pressure—Avoid listening to high volume levels for long periods to prevent possible hearing damage.

When you plug in your headset, lower the volume of the headset speaker before you put the headset on. If you remember to lower the volume before you take the headset off, the volume will start lower when you plug in your headset again.

Be aware of your surroundings. When you use your headset, it may block out important external sounds, particularly in emergencies or in noisy environments. Don’t use the headset while driving. Don’t leave your headset or headset cables in an area where people or pets can trip over them. Always supervise children who are near your headset or headset cables.

Batteries

Your phone comes with a Lithium ion battery, and you can order spare batteries.

You can find the battery installation instructions in the Cisco Wireless IP Phone 8821 and 8821-EX User Guide.

Caution

Use only approved batteries. Use of unapproved batteries might be dangerous, and invalidates the warranty on your phone.

The fully charged battery provides the following hours of service:

- Up to 11.5 hours of talk time (depends on phone firmware and charger version)

The following table shows the differences in talk time when you use:

- The new 4.35V Cisco Wireless IP Phone 8821 Desktop Charger and Cisco Wireless IP Phone 8821 Multi Charger

- The Cisco Wireless IP Phone 8821-EX Desktop Charger and Cisco Wireless IP Phone 8821-EX Multi Charger

- Up to 145 hours of standby time

Battery life depends on a number of factors including:

- On time—The battery life is reduced when the phone is turned on. Calls, messages, application use, Bluetooth use, and actions like menu navigation use power.

- Scan mode—Your phone can be set up to scan the access points in three different ways (Continuous, Auto, Single AP). If your phone uses Continuous or Auto scan modes, the phone requires more power, which reduces battery talk time.

Caution

The expected lifecycle for a battery is two years. Based on the average usage, this corresponds to approximately 500 charges. You can check the date printed on the battery to calculate the age of the battery. We recommend you to replace the battery when it reaches its end of life.

If you require longer talk times, you will find it useful to have a spare, charged battery.

For battery specifications, see the Cisco Wireless IP Phone 8821 Data Sheet and Cisco Wireless IP Phone 8821-EX Data Sheet at http://www.cisco.com/c/en/us/products/collaboration-endpoints/unified-ip-phone-8800-series/datasheet-listing.html

Damaged Battery Identification

Your phone battery can develop physical signs of damage. Physical signs include:

- Swelling

- Bending

- Broken end caps

Note

We recommend that you check the battery and battery compartment for physical signs of damage when you replace your battery.

Swollen Battery

Identification

- The battery doesn't sit flat on a table. It may rock if you touch the corners.

- The installed battery is not flat in the battery compartment.

- The back cover won't completely close (especially in the middle of the door)

- The battery doesn't fall out of the battery compartment when you try to remove it. You may think that you need to pry the battery out of the compartment.

Caution

Don't try to pry the battery out of the compartment.

Examples

The next image shows a swollen battery from the end.

The next image shows another swollen battery.

The next image shows a swollen battery in the battery compartment. Notice that the battery isn't flush with the compartment walls around the battery perimeter.

The next image shows the same swollen battery when the cover is put on. Notice that the middle of the cover is arched. The catches in the middle of the cover won't easily connect.

The battery may also swell along the length or width, which makes the battery hard to remove. Don't use any instrument to pry the battery out.

Bent Battery

Identification

The battery doesn't sit flat on a table. It may rock if you touch the corners.

Example

End Caps are Broken or Damaged

Identification

The plastic caps at the ends of the battery aren't properly attached.

Third-Party Accessories Overview

Accessories for the wireless phones are available from third parties.

Note

Cisco does not test third-party accessories. Cisco recommends that you test them in your environment before providing them to users.

Cisco does not endorse, support, or test third party cases or covers for the Cisco Wireless IP Phone 882x. Using your Cisco Wireless IP Phone 8821 with third party cases or covers may void your warranty.

Headsets

The wireless phone supports the use of third-party wired and Bluetooth wireless headsets.

For wired headsets, the phone requires a headset or ear bud with a 3.5 mm, 3-band, 4-conductor plug.

Important Headset Safety Information

Bluetooth Wireless Headsets

Using Bluetooth wireless headsets increases battery power consumption on your phone and results in reduced talk time.

For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but some barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.

Headset Choices

The audio portion of a headset must sound good to you and the person you are speaking to. Sound is subjective and we cannot guarantee the performance of any headsets. Some of the headsets on the sites listed below have been reported to perform well on wireless IP Phones.

For information about headsets, go to the following URLs:

http://www.plantronics.com

http://www.jabra.com

Note

We recommend that you test your headsets in your own environment to determine suitable performance.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.
