or moderate injury and/or damage to the equipment or property.
Warning indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
Danger indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.

provider.
NOTE
Changes or modifications not expressly approved by Mitel may void the user’s right to operate the
equipment.

Power Requirements
CAUTION
Endpoint Damage Hazard. If you are using an IP endpoint, make sure it is connected to the proper power supply
before powering on. Contact your system administrator for more information.
The IP endpoint requires any one of the following power supplies:
• Inter-Tel Power Supply Unit, part number 806.1114 or 806.1117 (Europe), or Mitel Universal Power Supply Unit,
part number 828.1766
• Red Hawk Single Port PowerSense
• An industry-standard IEEE 802.3af Power over Ethernet (PoE) power supply unit
If your endpoint uses a centralized PoE power supply unit, do not use the 48-volt DC Ethernet power adaptor. If
necessary, contact your system administrator for assistance before connecting your endpoint to the centralized power
source.
Make sure the endpoint is plugged into an uninterruptible power supply (UPS). If your endpoint is plugged into the
UPS and the power fails, it should remain powered on for about 10 minutes. If the endpoint is not plugged into a UPS
and the power fails, the current call is dropped and you will not be able to use the endpoint until the power is restored.
TM
, Part Number 901.0407
Software and Firmware Updates
If you are using an IP endpoint, it may require occasional software updates when new versions are available. The
endpoint is configured to download the updates automatically. Contact your system administrator for more
information. During the download process several messages are shown on the display that indicate the status of the
download. The final display message, FIRMWARE DOWNLOAD SUCCESS or BOOT DOWNLOAD SUCCESS,
indicates that the software or firmware update was downloaded successfully.
Immediately following the download your endpoint will re-synchronize with the telephone system by performing a
reset. When the display returns to your extension number, your user name, the time of day, and the date, the reset is
complete and you can use your endpoint again. During a reset, your endpoint (and all connected devices) lose
connectivity with the network for approximately 10 -20 seconds.
CAUTION
Endpoint Damage Hazard. Do not use your IP IP endpoint or disconnect it from the power supply while it is updating
software.This ensures that the software or firmware update is downloaded successfully. Do not disconnect the
endpoint from the power supply during the download process. Disconnecting the endpoint’s power supply while the
endpoint is downloading an update may cause serious damage to the endpoint.
Software Compatibility
Depending upon which software version your telephone system is using, some of the features included in this guide
may not be available for your endpoint. Check with your system administrator to see which software version your
telephone system currently uses and if there are any feature restrictions for your system.
Mitel® Model 8662 User Guide – Issue 12, October 2008Page iii
Endpoint Usage
This equipment is not for connection to the telephone network or public coin phone service. It is only for use when
connected to Mitel systems.
WARNING
When using your endpoint equipment, basic safety precautions should always be followed to reduce the risk of
fire, electric shock and injury to persons, including the following:
• Do not use this product near water, for example, near a bath tub, wash bowl, kitchen sink or laundry tub,
in a wet basement, or near a swimming pool.
• Avoid using an endpoint (other than a cordless type) during an electrical storm. There may be a remote
risk of electric shock from lightning.
• Do not use the endpoint to report a gas leak in the vicinity of a leak.
• Do not connect directly to the Public Switched Telephone Network (PSTN). Any connection of this
endpoint to an off premise application, an out of plant application, any other exposed plant application,
or to any equipment other than the intended application may result in a safety hazard, and/or defective
operation, and/or equipment damage. “Exposed plant” means where any portion of the circuit is subject
to accidental contact with electric lighting or power conductors operating at a voltage exceeding 300
volts between conductors or is subject to lightning strikes.
• The socket outlet, if used, shall be located near the equipment and shall be easily located by the user.
• Use only Mitel approved power adaptors. See “Power Requirements” on page iii.
• The handset supplied with the endpoint is not certified for use with any other phone. Use of the handset
with any other phone may have the potential to cause hearing loss in the event of a lighting strike on the
outside plant wiring.

The instructions in this guide are for using your Model 8662 endpoint. The Quick Reference
Guide located at the beginning of this user guide is an overview of frequently used features.
Your endpoint should be powered on and ready to use. If the display is blank, or if the display
name, extension number, or time or date are incorrect, contact your system administrator for
assistance.
The endpoint can operate in either Inter-Tel Protocol (ITP) mode or Session Initiation Mode
(SIP) mode. The operating mode determines which features and options are enabled on the
endpoint. This guide is for endpoints operating in ITP mode. If your endpoint is configured to
operate in SIP mode, request a copy of the Model 8600/8620/8622/8662 User Guide: Session Initiation Protocol (SIP) Mode, part number, 550.8024, from your system administrator.
Because a variety of voice mail products work with the Mitel 5000 system, this guide does not
include voice mail instructions. For voice mail instructions, refer to the voice mail user guide for
your system. For example, refer to the Enterprise Messaging, Basic Voice Mail, and Embedded
Voice Mail Card User Guide, part number 835.3205, or the NuPoint Messenger Messaging User
Guide (on the Mitel Web site

Endpoint Connectors
The endpoint connectors include:
• Handset port: Connects to a handset.
• Headset port: Connects to a headset.
• Personal computer (PC) port: Connects to a
computer or another 10/100 Ethernet device.
• LAN/Power port: Connects to a power supply.
Endpoint Signals
The endpoint has several audio and visual signals to indicate feature activity. The following are
a few helpful tips:
• Any buttons that are lit or blinking indicate call or feature activity.
• All endpoint button lamps illuminate at the same time for a few seconds when the endpoint
is reset or powered on.
• The following actions may cause an error tone:
o Pressing an invalid button combination.
o Selecting a restricted feature.
o Dialing a restricted or invalid number.
o Dialing too slowly between digits.
o Waiting too long before performing the next step.
To correct, hang up and try again.
• Many features “time-out” if you wait too long before performing the next step. If this
happens, you must start over.
• “Off-hook” means the handset is in use. “On-hook” means the handset is idle.
Comfort and Safety Tips
Page 6Mitel
Observe the following comfort and safety tips when using the endpoint:
• Do not cradle the handset: Prolonged use of the handset can lead to neck, shoulder, or
back discomfort, especially if you cradle the handset between your neck and shoulder. If
you frequently use the endpoint, you might find a headset more comfortable. See“Headset
Instructions” on page 7.
• Adjust the viewing angle: The built-in stand tilts to give you a better view of the buttons.
See “Adjusting the Viewing Angle” on page 9.
• Protect your hearing: Because prolonged exposure to loud sounds can contribute to
hearing loss, keep the volume at a moderate level. You can adjust the volume levels of the
handset receiver or headset. See “Changing Volume Levels” on page 9.
