Cleaning Tips for Wireless Telephones
Wireless Telephones may occasionally need to be cleaned to maintain appearance.
Generally, wiping the handset surface with a clean, water-dampened cloth or paper towel
will remove most films or residues. If the soiling is too stubborn for plain water, a mild
detergent solution may be us ed. Be sure to wipe away any detergent residue with a plain
water dampened cloth.
DO NOT IMMERSE WIRELESS TELEPHONES IN WATER OR OTHER LIQUID.
The Wireless Telephone may be cleaned with any general-purpose household glass and
surface type cleaner. Spray the cleaner on a soft cloth or paper towel, then wipe the
surface.
DO NOT SPRAY THE HANDSET DIRECTLY.
Pre-treated cloths, like those used for eyeglasses or cameras, may be used to clean the
Wireless Telephone. Pre-moistened towelettes may also be used. Avoid those containing
lanolin or aloe as it will leave a slippery residue.
The surface of the handset may be cleaned occasionally with disinfectants used for
general cleaning in a medical environment. Isopropyl alcohol may be used occasionally
applied by a damp cloth or paper towel. When using alcohol, do not rub the keypad
characters vigorously. Doing so will significantly degrade legibility.
• Do not use furniture polishes, waxes or plasticizer-based cleaner
(Armor All , etc.)
• Do not use lanolin, aloe, glycer in or other skin care type products.
• Do not apply any solvent such as acetone, mineral spirits etc.
• Do not directly spray or immerse the handset.
Should the headset connector become dirty, a scratchy or intermittent signal may be
experienced. To clean the connector, dip the non-padded end of either a wooden or paper
handled cotton swab in isopropyl alcohol. Gently insert in the connector and twist,
repeating several times. If available, blow compressed air into the connector to clear
debris.

2. Link Wireless Telephone System
Overview
Review this section if you are unfamiliar with the features and operation of the Link
Wireless Telephone System.
2.1 System Operation
The Link Wireless Telephone System (WTS) is a wireless communication system that
offers direct telephone access for incoming and outgoing calls anywhere within a facility.
The Link WTS consists of three basic components: the Master Control Unit (MCU), the
Base Station and SpectraLink Wireless Telephones. This diagram shows an overview of
system. Components are described below.
The Link Wireless Telephone System
•• Master Control Unit (MCU) – serves as the connecting point, or gateway, between
the Base Stations and the existing telephone system. One or more of these boxes
(approximately 12 x 3 x 7 inches) are typically installed in the telephone equipment
room and provide connectivity from the telephone system to the Link Wireless
Telephone System. Each MCU is hard-wired to one or more Base Stations, which in
turn provides the wireless link to each of the Wireless Telephones. The MCU
establishes the connection from the telephone line to the appropriate Base Station in
order to reach a Wireless Telephone.
Part Number: 72-0075-01-C-W.doc Page 3
SpectraLink Corporation Link WTS Installation and Operation
The MCU supports four Base Stations and up to 16 Wireless Telephones. Up to four
Link 150 M3 MCUs can be linked together for extended coverage area. Chained
MCUs support up to 64 Wireless Telephones maximum.
SpectraLink offers an analog MCU that works with telephone systems (CO, PBX or
Key Systems) with analog (loop start) ports. We also offer digital MCUs that work
with the most common brands of telephone systems' (PBX or key systems) digital
ports.
•• Base Stations – act as a radio transceiver to provide the communications signal
between the Wireless Telephone and the MCU. Base Stations are slightly larger than
a smoke detector and are typically mounted on the ceiling, in strategic locations
throughout the facility. A single Base Station can provide radio coverage for an area
of 5,000 to 50,000 square feet depending on building obstructions. Base Stations may
be located up to 2,200 cable feet from the MCU.
When a Wireless Telephone user makes or receives a call, the Wireless Telephone
and Base Station establish a digital radio communication link. As the user moves
around the coverage area, calls are “handed off” to the Base Station that is able to
provide the best radio signal (typically the closest Base Station). These handoffs
involve the Wireless Telephone establishing a communication link with another Base
Station and dropping the previous link.
•• Link Wireless Telephones – communicate with the Base Station using digital
spread spectrum transmission at 902-928 MHz. Employees can carry Wireless
Telephones to keep in contact as they move throughout the building. The Wireless
Telephones use on-premise wireless technology; they are not cellular or satellite
phones. They are connected to the facility's existing telephone system and, just like
wired telephones, can receive calls directly, receive transferred calls, transfer calls to
other extensions, and make outside and long distance calls (subject to the restrictions
applied in your facility.)

Part Number: 72-0075-01-C-W.doc Page 5
SpectraLink Corporation Link WTS Installation and Operation
3. Site Preparation
3.1 Required Materials
The following equipment must be provided by the customer.
1. Outlet Strip – Recommended for installations with more than one MCU. This
will allow the MCUs to be turned on and off together.
2. Cross-Connect Block – required to connect the telephone switch ports and the
Base Stations to the MCU.
3. 25 Pair Cables – RJ-21 male at MCU end, required to connect the MCU to the
cross-connect blocks.
4. Backboard space – the MCU is designed to be wall mounted to ¾” plywood
securely screwed to the wall.
5. Quick Clip Fuse – Required with an RCO410 Outdoor Base Station or when a
Base Station is located in a separate building from the Link 150 M3 MCU.
Recommended Quick Clip Fuse is available from Illinois Tool Works, Linx
Division, Model # SCP-2X2.
6. Base Station Mounting Hardware – If the Base Stations will be mounted on
finished walls or ceilings, a 4-5" long ¼" bolt, nuts, and washers will be required
for each Base Station mounted.
3.2 Determine Location of MCU
Each MCU is approximately 2.75 inches wide, 12.5 inches high, and 7 inches deep, and
weighs about 5 pounds. The unit is designed to be wall mounted over ¾”plywood.
Select a location for the MCU with sufficient backboard space and an available outlet.
The MCU must be within 2,200 feet of the Base Stations.
All digital interface modules must be within 250 feet of the telephone system.
See your telephone system specifications for distanc e limitations for analog modules.
Since the front panel is used for cabling and as an operator's console, mount the units so
the front panel is accessible.
If your system has more than one MCU, the units should be mounted
!!
vertically, side by side, physically touching the adjacent unit. Do not
stack units on top of one another. Stacked MCUs can cause overheating
and failure.
Part Number: 72-0075-01-C-W.doc Page 6
SpectraLink Corporation Link WTS Installation and Operation
4. Run Cable for System
4.1 Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor plans provided to
the installer. Base Stations can be mounted easily on raised or acoustical ceiling tiles, or
on the wall. Avoid locating Base Stations in high or hard-to-reach places, as this will
hinder maintenance, testing, or repositioning.
Wire Specifications
The customer's wire contractor is responsible for adhering to all local codes
!!
SpectraLink recommends UL-Listed Wire that conforms to the following specifications
for AWG, distance, and number of power pairs required for this installation.
Attenuation must not exceed 6.8 dB/1,000 feet @ 772KHz.
Wire that is already installed (spare house cable) can be used when it is available. House
cable will usually run from the MDF in the telephone equipment room to Intermediate
Distribution Frames (IDFs) spread throughout the facility. Install new wire from the
closest IDF to the Base Station. Be sure no bridge taps, multiples, or “Y” connections are
created or present.
Determine the amount of wire needed to connect the Base Station to the MCU by scaling
from a floor plan or a sketch, pacing, measuring, or estimating. Remember to include
enough wire to reach the ceiling.
The wire length between the MCU and each Base Station may not exceed
!!
Part Number: 72-0075-01-C-W.doc Page 7
2,200 cable feet.
Install an extra 25 feet of wire at the Base Station to allow for possible
relocation.
SpectraLink Corporation Link WTS Installation and Operation
4.2 Pull Cable
Pull the cable from the MCU location (usually in the telephone equipment room) to the
Base Station locations designated on the floor plans.
If the cabling exits the building, consult the telephone system manual, the
NEC, and local codes for instructions on providing lightning and other overcurrent protection.
When cabling an external Base Station or a Base Station with wiring that
exits the building, protect all Base Station wiring with the Quick Clip Fuse
(Illinois Tool Works, Linx Division, SCP-2X2) before bridging with other
Base Station power leads.
Run all cable before attaching the RJ-45 connectors to the Base Stations. Label both the
demarcation block end and the Base Station end of each wire with the Base Station
number using a wire tie marker or other form of marker.
Remove bridge taps, multiples, or "Y" connections to the Base Station wires;
!!
these will cause data transmission errors.
The area above some suspended ceilings is used as an environmental air
plenum. The National Electric Code requires that wire installed in plenums
be rated for plenum installation.
4.3 Terminate Cable at Base Station Locations
After running the wire to the Base Station location, terminate the wire using an RJ-45
modular crimp-on plug. Connect the data pair to pins 1 and 2 and the power pair to pins
7 and 8.
If the connection uses more than two pair, refer to the table on the following page.
To avoid damage to the connectors or crimps, be sure to run the wire to the
!!
Base Station before connecting the RJ-45 connectors.
