Important Electrical Considerations
Unplug all electrical appliances when you know an electrical storm is approaching.
Lightning can pass through your household wiring and damage any device connected to it.
This phone is no exception.
Warning!
Please do not attempt to unplug any appliance during an electrical storm.
Caution.- Changes or modifications to this product not expressly approved by L’nz’den, or
operation of this product in any my other than as detailed by this Operating Guide, could
mid your authority to operate this pruduct.
Range
Your new phone is designed to achieve the maximum possible range by transmitting and
receiving according to the highest spemfications set forth by the FCC. We have rated this
U0612—15 9
phone to operate at a maximum distance with the qualification that the range depends upon
the environment in which the telephone is used. Many factors limit range, and it would be
impossible to include all the variables in our rating. The Maximum Range rating of this
phone is meant to be used as a means of comparison against other range claims.
Telephone Line Problems
The FCC has granted the telephone company the right to disconnect service in the event
that your phone causes problems on the telephone line. Also, the telephone company may
make changes in facilities and services which may affect the operation of your unit.
However, your telephone company must give adequate notice in writing prior to such actions
to allow you time for making necessary arrangements to continue uninterrupted service,
If you are having trouble With your telephone service, you must first disconnect your
phone to determine if it is the cause of your problem. If you determine that it is the
cause, you must leave it disconnected until the trouble has been corrected.
Radio Interference
Radio interference may occasionally cause buzzing and humming in your cordless Handset, or
clicking noises in the Base Unit. This interference is caused by external sources such as
TV refrigerator, vacuum cleaner, fluorescent lighting, or electrical storm. Your unit is
NOT DEFECTIVE. If these noises continue and are too distracting, please check around your
home to see what appliances may be causing the problem. In addition, we recommend that the
Base Unit not be plugged into a circuit that also powers a major appliance because of the
potential for interference. Be certain that the antenna on the unit is fully extended when
needed.
In the unlikely event that you consistently hear other voices or distracting transmissions
on your phone, you may be receiving radio signals from another cordless telephone or other
source of interference.
Finally, it should be noted that some cordless telephones operate at frequencies that may
cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the
base of the cordless telephone should not be placed near or on top of a TV or VCR. If
interference is experienced, moving the cordless telephone farther away from the TV or VCR
will often reduce or eliminate the interference.
More Than One Cordless Telephone
Donfi operate two cordless phones too close to each other because of the interference.
This interference can be reduced by lowering your base unit antenna (reducing its range).
Privacy
Note.“ Cordless telephones are radio devices. Communications between the handset and the
base of your cordless telephone are accomplished by means of radio waves which are
broadcast over the open airways. Because of the inherent physical properties of radio
waves, your communications can be received by radio receiving devices other than your own
cordless telephone unit. Consequently, any communications using your cordless telephone
may not be private.

CIRCUIT DESCRIPTION AND
DIGITAL SECURITY CODE INFORMATION
CIRCUIT DESCRIPTION
1. OVER VIEW
The EXSQIIO is a digital spread spectrum cordless telephone which
meets with FCC Part 15 requirements. It provides the following
features:
Direct Sequence Spread Spectrum Modulation
20 Radio frequency Channels in 902 * 928MH2 ISM band
lOOmW maximum output power
Time Division Duplex operation
32kbps or 40kbps ADPCM voice CODEC
65538 security codes
Auto Channel codes
Auto Interference Avoidance
Auto least power control
2. Configurations
2. 1 Transmission
The voice signal is converted into 32kbps or 40kbps digital data by
ADPCM CODEC. The digital data is fed to scrambler, differential
encoder, spreader which is responsible for the Spread Spectrum
modulation. The SS Chip sends out digital data which is made by the
spread spectrum sequence. This digital data having a 1.2Mbps data
rate is filtered and upper converted to RF by DBPSK (Differential
Binary Phase Shift Keying) modulator. Then. filtered by LPF (Low
Pass Filter) to suppress the out—of—band spurious of the antenna
transmission signal.
2. 2 Reception
The receiver is direct conversion type, The incoming signal is
Uc61245 19
passes through the RF BPF (Band Pass Filter). Down-conversion to
quadrature base band signal is done using a matched pair of mixers
and a 90° phase splatter for the L0 (Local). The SS Chip calculates
the correlation from the spreading code and the outputs the detected
voice data to ADPCM CODEC. Finally, the ADPCM CUDEC outputs
received analog signal.
2.3 Duplexing
The EXSQIiO can conmunioate by using Time Division Duplexing. It
uses same frequency in both transmission and reception. It has 2
msec time frame of one transmission and reception cycle. This frame
signal is generated by SS Chip and is provided to all other circuits.
2. 4 Control
The CPU controls the RF frequency channels, RF power, ADPCM GODEC
and audio signal switching. It also set up the spreading code other
data of the SS Chip. Before established the comnunication link,
EXSQliO searches vacant RF channel and then transmits RF signal at
the vacant channel. Initially, it output the minimum RF power to
maintain communication in order to minimize the interference to
other cordless telephones. The CPU generates a random security code
out of 65536 codes, which can protects customers privacy.

Equipment Description
The model EXSQHO is a telephone terminal device that is designed
for voice operation in a similar fashion to an ordinary residential
or business telephone without the inconvenience and restrain of a
handset cord.
This device consists of a base unit and a handset The base unit is
intended to connect to standard telephone modular jacks and is
supplied electric power from a standard AC power line by using with
the AC Adapter. The handset is powered from an internal battery pack.
The EXSQHO Cordless Telephone operates by means of a full duplex
radio frequency TX/RX system in 902 — 928 MHZ band with Spread
Spectrum Technology. Theses radio frequency systems operate in
accordance with Part 15 of the FCC Rules.
The EXSQHO has been specifically designed to comply with the
requirements set forth in Part 68 of the FCC Rules as well as the
Part15 requirements. The specifications are below:

3. Power Control:
During the measurement, the automatic power control circuit was
disabled by controlling with personal computer (PC) connected the
unit under test. The RF output required for testing would be set by
personal computer
4. Serial port:
The serial port is a terminal that is mainly used as corrmand port
for setting the unit for specified test mode and/or read out the
data from the unit under test to verify the operational condition.
Note that Bit Error Ratio (B.E.R) of the unit may be available
through this port as well.
Nature of impedance for serial port would be classified as CMOSs
input/output port level, therefore, connection of serial port would
not affect the power to the antenna.
5 Maximum allowable output power‘
Please be advised that we designed the rated output power for both
unit as +18 dBm (= 0, 063 W: 2dB below 0.1 watts).
Just for your reference, the units (both base and handset) could be
automatically changed the RF output power levels as follows;
Hi — Power :+18dBm
MID —Power : +7dBm
L0 — Power : —3dBm
