GETTING STARTED
Some cordless telephones operate at frequencies
that may cause interference to nearby TVs,
microwave ovens 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, microwave oven or VCR. If such
interference continues, move the cordless
telephone farther away from these appliances.
Certain other communication devices may also
use the 2.4GHz frequency for communication
and, if not set properly, these devices may
interfere with your new telephone.
Typical devices that may use the 2.4GH
frequency include wireless audio/video senders,
wireless computer networks and multi-handset
cordless telephone systems.
CHOOSING BASE UNIT LOCATION
When selecting a location for your base unit
(which records and displays the indoor tempera-
ture), please observe the following guidelines:
•Choose a location that provides easy access
to a 120-volt AC power source.
•Choose a location that will allow the telephone
cable to reach a telephone jack. (You can use
an extension cable if necessary).
•Place the base unit as high as possible to get
a better radio frequency range with the
handset. You may need to try several
locations – such as upstairs, or near a first-
floor landing – to find the best range. Solid
structures, such as walls and doors, may
reduce the signal strength.
•Do not place the base unit near a sink, bathtub
or shower.
•Do not place the base unit near large metal
objects or electronic appliances that may
cause radio interference. Some of these
include: mirrors, filing cabinets, electric
stoves, washing machines, microwave ovens,
televisions, fluorescent lights or other
telephones.
•Do not place the unit near heat sources, such
as radiators or air ducts, or in a place subject
to direct sunlight.
CONNECTING THE BASE UNIT
To connect the base unit:
1. Plug the AC adaptor into the power jack on
the back of the base, and then plug the
other end into an electrical outlet.
2. Plug the telephone line cord into the
telephone line jack on the back of the base
unit, and then plug the other end into a
modular phone jack.
NOTE: The adaptor is shipped with the product.
Please check the label on the adaptor to make
sure you are using the right one.
NOTE: You need a RJ11 modular phone jack. If
you do not have a modular jack, call your local
phone company to find out how to get one
installed.
REMOTE SENSOR SETUP
This product measures the outdoor temperature
and then transmits the information to the base
unit. It can be used with up to 2 other remote
sensors to transmit data back to the base unit.
Additional remote sensors that measure tempera-
ture are sold separately.
NOTE: If you are using more than one remote
sensor, be sure to select a different channel for

line and AC power source?
•If the telephone line is not properly
connected to the base unit “NO LINE” will
appear on the handset display.
•Is the AC power source turned on at the
socket?
•Are the batteries properly installed in the
handset?
Dial tone is OK, but cannot dial out
Try moving the handset closer to the base unit.
•If this doesn’t work, try a different position
for the base unit. (Typically, the higher you
place the base unit, the better the recep-
tion).
•The battery charge level may be low. Check
the LCD display for the low battery-warning
signal. If the battery is low, place the
handset in the base unit’s charging cradle to
charge.
•Check the power connection by switching
off the power at the main socket. Wait a
few seconds, then switching it back on.
•Check to make sure that the phone and
base unit are within the range of transmis-
sion.
•The handset may be unable to find the base
unit. Try moving the handset closer to the
base unit. If the problem persists, try
moving the base unit in a suitable position
nearer to the handset.
•If you have registered additional handsets
to the same base unit, make sure they are
not already on a call. The LCD display on
your handset will display EXT IN USE if the
line is engaged.
•The dial mode setting may be incorrect. See
the DIAL MODE section for instructions on
how to change the dial mode.
Handset does not ring
Check that you have not turned off the ringer
volume level. Also, you may have too many
extension phones on your line. Try unplugging
some phones.
Call was disconnected
Please move the handset closer to the base unit.
Also, you may want to consider moving the base
unit to achieve a greater range of transmission.
Keys do not work / [KEY] shows on screen
The symbol means that the keypad lock feature
has been activated.

Phone beeps
The battery may need to be recharged.
•Put the handset into the charging cradle of
the base unit. It may take up to 15 hours to
fully recharge the battery.
•Your handset may temporarily lose its
synchronization with the base unit due to
radio interference in your area. When this
happens, “OUT OF SERVICE” shows on the
handset display.
•If you do not wish to hear the beep tone,
you can turn it off. See the KEY TONE
section for more information.
Low battery warning
If you just recharged the batteries, but keep
getting a low battery warning, the batteries may
need to be replaced.
•Rechargeable batteries gradually lose their
ability to store a charge the older they get.
Simply replace the battery with a new one.
MULTI-HANDSET USE
Cannot register new handset
Sometimes it helps to unplug and then reconnect
your base unit to its AC power source before you
start the registration procedure.
•You may have already registered 4
handsets to the base unit.
•If you are replacing a faulty handset, make
sure you have fully removed the faulty one
before registering the new one.
•If you are still experiencing problems, you
will need to reset all the registrations then
start over.
Cannot dial out
Only one outside call and one intercom call can
take place at the same time. Make sure no one
else is already using the phone; if so, you will see
the EXT IN USE symbol on the handset display
area.
All handsets show “OUT OF SERVICE” and
telephone will not work
Reset your telephone, and then try the registra-
tion process again.
•If you are still experiencing problems, reset
and then re-register all your handsets one-
by-one.
CALLER ID
No Caller ID display
You must subscribe for Caller ID services through
your telephone network provider for the Caller ID
to display on this telephone.
•If the caller’s number does not exactly
match what you have entered in your phone
book, including the STD code and any
prefixes, the phone book cannot match the
name to the Caller ID. Check the phone
book to make sure the full number is stored
there in the correct sequence.
•Is the battery fully charged? If not, try
recharging or replacing the battery.
•Make sure the base unit is connected to a
non-switched AC outlet.
•Disconnect the base unit from the plug and
plug it in again.
Caller ID error message
The phone displays this message if it detects
anything other than valid Caller ID information
during the silent period after the first ring.
•This message indicates either the presence
of noise on the line, or that an invalid
message has been sent from the telephone
company.
REMOTE SENSOR
Cannot find remote sensor
Check the sensor batteries, channel number and
location.
•Make sure the sensor low battery icon isn’t
being displayed. Make sure the sensor is
within range of the base unit. Press RESET
on sensor to initiate a sensor search or
press and hold TEMP on the base unit to
search for sensors.
“HI” shows on display
When the outdoor temperature reaches 40 °C (104
°F) or higher, the base unit will display “HI”.
“LO” shows on display
When the outdoor temperature falls below –20 °
C, the base unit will display “LO”.
CAUSES OF POOR RECEPTION

This product is designed to give you years of
service if handled properly. Please observe the
following guidelines:
•Avoid putting the phone near heating
appliances and devices that generate
electrical noise, such as motors or
fluorescent lamps.
•Do not expose your telephone to direct
sunlight or moisture.
•Do not tamper with the internal components.
•Do not mix new and old batteries, or
batteries of different types.
•Avoid dropping the phone and other rough
treatment.
•Clean the phone with a soft cloth, but never
use a strong cleaning agent or abrasive
powder. This will damage the finish.
•Remove the batteries if storing this product
for a long period of time.
•Periodically clean the charge contacts on
the handset and base unit with a clean pencil
eraser.
•Do not make any changes or modifications
to this product.
•Retain the original packaging in case you
need to ship the phone at a later date.
MAINTENANCE AND CARE
The freedom that your cordless telephone can
offer is fully dependent on the performance of
the rechargeable battery in the handset. To
maximize the battery performance, follow these
guidelines:
MAXIMIZE BATTERY PERFORMANCE
Charge it for a full 15 continuous hours
•Before initial use of your new battery,
charge it for 15 continuous hours. The
proper initial charging is very important to
maximize the battery performance.
Keep the contacts clean
•You can never fully recharge the battery if
the contacts are dirty. Clean all the contacts
(two at the bottom of handset and two in the
base cradle) periodically using a pencil
eraser.
Do not replace the handset in the base unit
cradle after each call
•Repeated short charging creates a “memory
effect” in the battery. Once a rechargeable
battery acquires this “short memory”, it
sends a “CHARGE BATTERY” signal even
when it is almost fully charged. The battery
then needs to be charged frequently. To
avoid this, leave the handset away from the
cradle until it really needs recharging.
Refresh battery
•If your battery seems to need recharging
more often than usual, it may have lost part
of its charging capacity because of
premature recharges. To bring back its full
capacity, try “refreshing” the battery:
1. First discharge the battery by leaving
the handset in TALK mode until the
battery low indicator turns on.
(Disconnect the base unit from the
telephone line, so that your line is not
busy all the time).
2. Then charge it for 15 continuous
hours.
3. Repeat the above once more.
