Set-up
Thank you for purchasing a First Alert Brand In/Outdoor
Wireless RF Weather Station - Model FWS-101. The main
unit is designed to receive temperature signals from
maximum 3 remote sensors in different locations, and it is
also equipped with a snooze alarm.
Both the Weather Station (receiving unit) and the Remote
sensor (sending unit) require batteries. Insert the batteries in
the Weather Station before doing so for the remote units.
Battery Installation for your Weather Station
To install batteries in the Weather Station:
1 Press the door tab and slide down the battery cover at the
back of the main unit. Insert 2 AAA size batteries
according to the “+” and “-” polarity marks shown in the
battery compartment.
2 The (—) dash icon will flash at the lower part of the screen.
The main unit is now ready to register with and receive
the RF temperature signal from the remote sensor(s).
Battery Installation for your Wireless Remote Sensor
1 Lift off the bracket stand of the RF remote sensor, then
use a small Philips screwdriver to remove the battery
cover screws.
2 Insert 2 AAA size batteries according to the “+” and “-”
polarity marks shown in the battery compartment.
3 Once the batteries
are inserted, the
sensor will transmit
the temperature
signal to the
receiving unit at 30
second intervals or
when there is a 0.2°C change in temperature. The sensor
is also equipped with a manual transmission button (TX).
You can trigger the sensor to transmit the temperature
signal by pressing this (TX) button for 2 seconds.
4 Once the main unit has received the temperature signal,
the icon “ 1 “ and the temperature of the corresponding
sensor will be displayed on the lower part of the screen.
5 If you have more than one remote sensor, please do not
insert batteries for all remote sensors at the same time.
You have to install the batteries for one sensor first. After
registration of the first sensor is completed (i.e. the
temperature is displayed on the screen), then insert the
batteries for the second sensor and complete registration
before proceeding with the third sensor.
Before replacing
the back cover, try the test described in the Operations
section of the manual to make sure the two units are
communicating.
NOTE
: In order to protect our environment, please dispose
the old batteries promptly and properly. Do not burn or
bury them.
To ensure proper operation, please read this instruction
manual carefully and keep for future reference.
Troubleshooting
If the display for a particular channel shows a dash (—), check: the
following items:
• The remote unit of that channel is still in place and connected.
• The batteries of both units are fresh. Replace as necessary.
• The transmission is within range and path is clear of obstacles and
interference. Shorten the distance when necessary.
• Avoid signals from other household devices, such as home security
systems and entry controls, that may interfere with this product and
cause temporary reception failure. This is normal and it doesn’t affect
the general performance of the product. Temperature transmission
and reception of readings will resume once interference recedes.
The main unit and remote sensor contain no user serviceable parts
Precautions
1. Do not clean the units with abrasive or corrosive compounds. It
may scratch the plastic parts and corrode the electronic circuits.
2. Do not subject the units to excessive force shock, dust,
temperature or humidity, which may result in malfunction, shorter
electronic life span, damaged batteries and distorted parts.
3. Do not tamper with the units’ internal components. Doing so will
invalidate the warranty on the unit and may cause unnecessary
damage battery and distorted parts.
4. Do not subject the units to excessive exposure to direct sunlight.
5. Never immerse in water or expose to heavy rain. The remote
sensor is of a splash-proof design.
6. Always read the user’s manual thoroughly before operating the
unit.

FCC WARNING!
This equipment generates and uses radio frequency energy and if not
installed and used properly, that is, within strict accordance with the
manufacturer’s instructions, may cause interference to radio and television
reception. It has been tested and found to comply with the limits of a
Class B digital device in accordance with Part 15 of FCC rules, which are
designed to provide reasonable protection against such interference in a
residential installation. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
1. Reorient the TV/ radio antenna.
2. Relocate the receiver away from the TV/radio receiver.
If necessary, the user should consult the dealer or an experienced radio/
television technician for additional suggestions.
The user may find the following booklet prepared by the Federal
Communications Commission helpful: “How to Identify and Resolve TV
Interference Problems”. This booklet is available from the U.S.
Government Printing Office, Washington, D.C. 204502, Stock No. 004-
000-00345-4
FCC Notice
The user is cautioned that changes or modifications not expressly
approved by the manufacturer could void the user’s authority to
operate the equipment. Linear radio controls provide a reliable
communications link and fill an important need in portable wireless
signaling. However, there are some limitations which must be
observed.
For U. S. installations only: The radios are required to comply with
FCC Rules and Regulations as Part 15 devices. As such they have a
limited transmitter power and therefore limited range. A receiver cannot
respond to more than one transmitted signal at a time and may be
blocked by radio signals that occur on or near their operating
frequencies. Changes or modifications to the device may void FCC
compliance. Infrequently used radio links should be tested regularly to
protect against undetected interference or fault.
