OPERATIONAL WARNINGS
For Vehicles Equipped with an Air Bag: Do not place a portable radio product in
the area over the air bag or in the air bag deployment area. An air bag inflates with
great force. If a portable radio is placed in the air bag deployment area and the air bag
inflates, the radio product may be propelled with great force and cause serious injury
to occupants of the vehicle.
Potentially Explosive Atmospheres: Turn off your radio product, prior to entering
any area with a potentially explosive atmosphere, unless it is a radio product type
especially qualified for use in such areas (for example, Factory Mutual Approved).
Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even
death.
The areas with potentially explosive atmospheres referred to
above include fueling areas such as below decks on boats, fuel or
chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area where you would normally be advised
to turn off your vehicle engine. Areas with potentially explosive
atmospheres are often but not always posted.
Batteries: All batteries can cause property damage and/or bodily injury, such as burns
if a conductive material such as jewelry, keys, or beaded chains touches exposed terminals. The conductive material may complete an electrical circuit (short circuit) and
become quite hot. Exercise care in handling any charged battery, particularly when
placing it inside a pocket, purse, or other container with metal objects.
Cleaning and Drying Considerations: Using a leather carry case may help protect
the surfaces and help prevent liquids (e.g., rain) from entering into the interior of the
radio product. This product is not waterproof, and exposing the unit to liquids may
result in permanent damage to the unit.
If your Wireless Telephone interior gets wet, then do not try to accelerate drying with
the use of an oven or a dryer as this will damage the Wireless Telephone and void the
warranty. Instead, do the following: 1. Immediately power off the Wireless Telephone.
2. Remove battery pack from Wireless Telephone. 3. Shake excess liquid from Wire-
less Telephone. 4. Place the Wireless Telephone and battery pack in an area that is at
room temperature and has good airflow. 5. Let the Wireless Telephone and battery
pack dry for 72 hours before reconnecting the battery pack and/or powering on the
Wireless Telephone. If the Wireless Telephone does not work after following the steps
listed above, contact your dealer for servicing information.

ELECTRO MAGNETIC INTERFERENCE/
COMPATIBILITY
NOTE: Nearly every electronic device is susceptible to electromagnetic interference
(EMI) if inadequately shielded, designed or otherwise configured for electromagnetic
compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your
radio product in any facility where posted notices instruct you to do so. Hospitals or
health care facilities may be using equipment that is sensitive to external RF energy.
Medical Devices
Pacemakers: The Health Industry Manufacturers Association recommends that a minimum separation of 6 inches (15 cm) be maintained between a handheld wireless
radio product and a pacemaker. These recommendations are consistent with the independent research by, and recommendations of, Wireless Technology Research. Persons with pacemakers should:
•ALWAYS keep the radio product more than 6 inches (15 cm) from their pacemaker when the radio product is turned ON.
•Not carry the radio product in a breast pocket.
•Use the ear opposite the pacemaker to minimize the potential for interference.
•Turn the radio product OFF immediately if you have any reason to suspect that
interference is taking place.
Hearing Aids: Some digital wireless radio products may interfere with some hearing
aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives.
Other Medical Devices: If you use any other personal medical device, consult the
manufacturer of your device to determine if it is adequately shielded from external RF
energy. Your physician may be able to assist you in obtaining this information.
Use While Driving
Check the laws and regulations on the use of radio products in the area where you
drive. Always obey them. When using the radio product while driving, please:
•Give full attention to driving and to the road.
•Use hands-free operation, if available.
•Pull off the road and park before making or answering a call if driving conditions
so require.

SPECIFIC ABSORBTION RATE (SAR) INFORMATION
Your wireless handheld portable telephone is a low power radio transmitter and
receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.
In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless phones. Those guidelines are
consistent with the safety standards previously set by both U.S. and international standards bodies:
•ANSI C95.1 (1992) American National Standards Institute
•NCRP - Report 86 (1986) National Council on Radiation Protection and Mea-
surements
•ICNIRP (1996) International Commission on Non-Ionizing Radiation Protection;
•DHWC - Safety Code 6 Department of Health and Welfare Canada
Those standards were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial
safety margin designed to assure the safety of all persons, regardless of age and
health. The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC
is 1.6W/kg. Tests for SAR are conducted using standard operating positions specified by the FCC with the phone transmitting at its highest certified power level in all
tested frequency bands. Although the SAR is determined at the highest certified
power level, the actual SAR level of the phone while operating can be well below the
maximum value. This is because the phone is designed to operate at multiple power
levels so as to use only the power required to reach the network. In general, the closer
you are to a wireless base station antenna, the lower the power output. Before a phone
model is available for sale to the public, it must be tested and certified to the FCC that
it does not exceed the limit established by the government-adopted requirement for
safe exposure. The tests are performed in positions and locations (e.g., at the ear and
worn on the body) as required by the FCC for each model. While there may be differences between the SAR levels of various phones and at various positions, they all
meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in
compliance with the FCC RF emission guidelines. SAR information on this model
phone is on file with the FCC and can be found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching on FCC ID IYGSNP2400 or
IYGRNP2400. Additional information on Specific Absorption Rates (SAR) can be
found on the Cellular Telecommunications Industry Association (CTIA) web site at
http://www.wow-com.com.
The only authorized headsets that may be utilized with the SNP2400 or RNP2400 are
those obtainable from SpectraLink or it's reseller partners.
The measured SAR of the SNP2400 Wireless Telephone is
Phone Operation Normal Position: Hold the phone as you
would any other telephone, with the earpiece to your ear and
speak into the microphone. The internal antenna is then positioned properly.

ABOUT BATTERY PACKSAND CHARGERS
The Model 8664, 8665, and 8668 endpoints require a charged battery pack to operate.
The Nickel Metal Hydride (NiMH) rechargeable battery pack will need to be charged
periodically. A charged battery pack provides four hours of talk time or 80 hours of
idle time. To save battery power, it is recommended that you place the endpoint in
idle mode at the end of every call (see page 12).
The battery icon indicates the amount of charge remaining in the battery pack. The
level indications are approximations of the remaining battery pack life. They do not
indicate equal amounts of battery pack Life. When only one level remains, ()
the battery pack needs to be charged. If you are on a call, you will hear a soft beep
through the earpiece every six seconds. You have 15-30 minutes of battery life left. If
the battery pack is critically low, and you are not on a call, the Low Battery message
is displayed, and a loud beep will sound. When the battery pack is critically low, the
endpoint will not work until the battery pack is charged.
At some point you may need to replace the battery pack for your endpoint.
NOTE: The battery pack can be changed while the call is still in progress. Do not press
End Call. Place call on Hold. Quickly remove the discharged battery and replace with a
charged battery, power on the endpoint, and press Start Call to resume the call in
progress.
FINDING YOUR WAY
To remove and replace the battery pack on the Model 8664 and 8668:
Press down on the latch on the battery pack to release the battery. The battery pack
releases outward and you can remove it from the endpoint. To replace the battery
pack, slide the lip of the battery pack into the bottom of the cavity and push the top of
the battery pack until it snaps into place.
To remove and replace the battery pack on the Model 8665:
Hold the endpoint in one hand with the keypad facing up. Press both battery pack
release buttons (on the left and right sides of the endpoint) at the same time. The battery pack will release downward. You may catch it with the palm of your other hand.
If the battery pack does not release, gently shake the endpoint while pressing both
release buttons. Do not pry.
NOTE: Improper disposal of battery packs can damage the environment. Contact your
system administrator for instructions on how to recycle or properly dispose of used battery packs.
Inter-Tel® Model 8664/8665/8668 User Guide

You can charge the endpoint’s battery pack using a desktop charger (Models 8664 and
8665), a dual charger (Models 8664, 8665, and 8668) or a quad charger (Models 8665
and 8668). The chargers require approximately one and one half to two hours to
charge the battery pack completely.
FINDING YOUR WAY
NOTE: Take care not to short the battery contacts on the battery pack with metal
objects such as coins, keys or paper clips. Shorting the contacts can cause permanent
damage.
NOTE: Battery packs are not interchangeable. The Model 8665 uses the distinctive
square model BPX100 battery pack. The battery packs for the Model 8664 and 8668
endpoints are the same rounded shape but different colors. The Model 8664 BPE100
battery pack is black, the Model 8668 BPN100 battery pack is steel blue.
Only use Inter-Tel battery packs with Inter-Tel endpoints.
Do not dip the battery pack in water or throw into fire.
Do not throw away the battery pack with your domestic waste. Take used battery
packs to an appropriate collection point for recycling or send them back to your supplier
or servicing agent.
