Warning:
• During registration, the phone checks the DHCP options in the default sequence of 66,
160, 159, 150, 60, 43, and 125 to obtain the URL of the provisioning server. The rst valid
conguration response the phone receives (which includes a 401 authorization request)
will determine its provisioning server. Ensure that your server is properly congured to
process phone registrations successfully.
• By default, 802.1X authentication is disabled on your phone.
If your network uses the 802.1X protocol, ensure that you enable 802.1X authentication on
your phone by accessing Settings > Wi-Fi > <Prole name> > WLAN conguration.
Otherwise, your phone will fail to connect to the network.
• If your phone has HTTP connection issues during the registration, you might be prompted
to set up an HTTP proxy server on the phone. The HTTP proxy setting is only required for
the phones registered to Webex Calling or BroadWorks. For more information about how to
set up the HTTP proxy, see HTTP proxy settings.

CONFIDENTIAL DRAFT
Cisco Wireless Phone 9821 User Guide | 3 - Phone setup | 48
• Up to 11.5 hours of talk time
• Up to 145 hours of standby time
Battery life depends on a number of factors, including:
• On time—Battery life decreases when the phone is turned on. Activities such as calls, messaging,
application use, Bluetooth usage, and menu navigation consume power.
• Scan mode—The phone can scan access points in three different ways (Continuous, Auto, and
Single AP). Using Continuous or Auto scan modes requires more power, which reduces talk time.
• Background noise lter—Talk time may reduce to 8.5 or 9.5 hours when this feature is turned on.
If you need longer talk times, it is advisable to have a spare, fully charged battery available.
Warning:
Use only approved batteries that come with your Cisco Wireless Phone 9821 or are specied by
Cisco. Use of unapproved batteries might be dangerous and invalidates the warranty on your
phone. To obtain replacement batteries, contact your local dealer and use only Cisco specied
batteries with the correct part number.
Note:
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.

Headsets
You can use wired and Bluetooth headsets with your phone. Although we perform some internal testing
of third-party wired and Bluetooth wireless headsets for use with Cisco Wireless Phone 9821, we do not
certify or support products from headset or handset vendors. Because of the inherent environmental and
hardware inconsistencies in the locations where phones are deployed, there is not a single best solution
that is optimal for all environments. We recommend that customers test the headsets that work best in
their environment before deploying a large number of units in their network.
We recommend the use of good quality external devices, like headsets that are screened against
unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of these
devices and their proximity to other devices such as cell phones and two-way radios, some audio noise
may still occur.
CONFIDENTIAL DRAFT
Cisco Wireless Phone 9821 User Guide | 8 - Accessories | 106
Standard headsets
You can use a wired headset with your phone. The headset requires a 3.5 mm, 3-band, 4-connector plug.
We recommend the Cisco Headset 520 Series. This headset offers outstanding audio performance. It has
a 3.5 mm audio plug that you can plug into the wireless phone. You can also use the headset and its inline
controller with some of the desk phones in the Cisco IP Phone 8800 Series. For more information on the
headset, see https://www.cisco.com/c/en/us/products/collaboration-endpoints/headset-500-series/

If you plug a headset into the phone during an active call, the audio path automatically changes to the
headset.
Bluetooth headsets
You can use a Bluetooth® headset with your phone. When you use a Bluetooth wireless headset, the
headset usually increases battery power consumption on your phone and may result in reducing battery
life.
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.
We recommend the Cisco Headset 560 Series and Cisco Headset 730. These headsets offer outstanding
audio performance. For more information about the headsets, see https://www.cisco.com/c/en/

Cisco recommends the use of good quality external devices (such as headsets) that are shielded against
unwanted radio frequency (RF) and audio frequency (AF) signals.
CONFIDENTIAL DRAFT
product safety and compliance | 1 - Safety and performance information | 8
Depending on the quality of these devices and their proximity to other devices such as mobile phones or
two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or
more of the following actions:
• Move the external device away from the source of the RF or AF signals.
• Route the external device cables away from the source of the RF or AF signals.
• Use shielded cables for the external device, or use cables with a better shield and connector.
• Shorten the length of the external device cable.
• Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of
external devices, cables, and connectors. The system will perform adequately when suitable devices are
attached using good quality cables and connectors.
CAUTION:
In European Union countries, use only external headsets that are fully compliant with the EMC
Directive [89/336/EC].
Phone behavior during times of network congestion
Anything that degrades network performance can affect phone audio and, in some cases, can cause a call
to drop. Sources of network degradation can include, but are not limited to, the following activities:
• Administrative tasks, such as an internal port scan or security scan.
• Attacks that occur on your network, such as a Denial of Service attack.

THIS DEVICE MEETS THE LIMITS AS REFERENCED BY ISED RSS-102 R5 FOR EXPOSURE TO RADIO
WAVES
Your device includes a radio transmitter and receiver. It is designed not to exceed the General populace
(uncontrolled ) limits for exposure to radio waves (radio frequency electromagnetic elds) as referenced
in RSS-102 which references Health Canada Safety Code 6 and include a substantial safety margin
designed to assure the safety of all persons, regardless of age and health.
As such the systems are designed to be operated as to avoid contact with the antennas by the end user.
It is recommended to set the system in a location where the antennas can remain at least a minimum
distance as specied from the user in accordance to the regulatory guidelines which are designed to
reduce the overall exposure of the user or operator.
The device has been tested and found compliant with the applicable regulations as part of the radio
certication process.
Maximum SAR for this Model and Conditions Under Which it was Recorded
Maximum Head SAR (1g) 1.371 W/kg

This wireless phone contains a radio transceiver. The radio transceiver and antenna have been designed
to meet the RF emission requirements for human exposure as specied by the FCC as well as by other
agencies from other countries. These guidelines were developed by the industry based on guidance
from the World Health Organization (WHO). These industry standards have been developed to include
additional safety margins to ensure that the user is exposed to the least amount of RF radiation.
The radio transceiver uses a non ionization type of radiation as opposed to an ionized radiation such as
an X-Ray wave.

The exposure standard for these devices references a unit of measure known as SAR. The limit as set by
the FCC is 1.6W/kg. The tests for this emission level is done in an independent laboratory who employs
test methods and operating positions reviewed by the FCC and other agencies.
Before the phone was placed on the market, the product was tested and certied in accordance with the
FCC regulations to verify that the product did not exceed the FCC SAR requirements.
Additional information on SAR and RF Exposure can be obtained off the FCC website at: http://
www.fcc.gov/oet/rfsafety
There is no conclusive proof that these mobile phones are or are not a health risk. The FDA and numerous
researchers are continuing studies of RF radiation and health issues. Additional information on this
subject can be obtained from the FDA web site at: http://www.fda.gov
Cisco Wireless Phone 9821 operates at power levels that are 5 to 6 times lower than most standard
cellular, Personal Communications Service (PCS), or Global System for Mobile Communication (GSM)
phones. This lower power coupled with a lower transmitter duty cycle reduces the user’s exposure to the
RF fields.
There are several suggested methods to reduce exposure for the user. Among those include:
1. Using a hands-free handset to increase the distance between the antenna and the head of the user.
2. Orienting the antenna away from the user.

Compliance Statements for New Zealand
Permit to Connect (PTC) General Warning
The grant of a Telepermit for any item of terminal equipment indicates only that Spark NZ has
accepted that the item complies with minimum conditions for connection to its network. It indicates no
endorsement of the product by Spark NZ, nor does it provide any sort of warranty. Above all, it provides no
assurance that any item will work correctly in all respects with another item of Telepermitted equipment
of a different make or model, nor does it imply that any product is compatible with all of Spark NZ network
services.
Use of IP Networks with the PSTN
Internet Protocol (IP) by its nature introduces delay into speech signals as each data packet is formulated
and addressed. Spark NZ Access Standards recommends that suppliers, designers and installers using
this technology for calls to or from the PSTN refer to ITU E Model requirements in the design of their
networks. The overall aim is to minimise delay, distortion and other transmission impairments, particularly
for those calls involving cellular and international networks, which already suffer extensive delay.
CONFIDENTIAL DRAFT
product safety and compliance | 2 - Compliance statements | 17
The Use of Voice Compression Through the PSTN
Because of the extensive delay already experienced when calling cellular and international networks,
some of which is already caused by their use of voice compression technologies. Spark NZ Access
Standards will only approve G711 voice technology for use on the PSTN. G711 is an ‘instantaneous
speech-encoding technique’ whereas G729 and all its variants are considered ‘near instantaneous’
introducing additional delay into the speech signal.
Echo Cancellation
Echo cancelers are not normally required in the Spark NZ PSTN because geographic delays are
acceptable where CPE return loss is maintained within Telepermit limits. However, those private networks
that make use of Voice-over-IP (VoIP) technology are required to provide echo cancellation for all voice
calls. The combined effect of audio/VoIP conversion delay and IP routing delay can cause the echo
cancellation time of 64 mS to be required.
