3. Set up Guide

3.1 Battery install

Note: To avoid operating problems, please take note of battery polarity
before/when inserting any Alkaline Batteries (permanent damaged could be
introduced by inserting the battery in wrong direction). Use good quality
Alkaline Batteries and avoid rechargeable batteries.

1) Insert two AAA batteries into the remote sensor

2) Insert three AA batteries into the weather station.

3) Wait 3 minutes or until the outdoor temperature is displ ayed i n the weat her station.
Do not press any keys before outdoor sensor data received.

4) Mount the units, ensuring that the receiver can still pick up the signal from the

transmitter. To measure outdoor temperature, place the transmitter outdoors. It will
transmit the temperature from its location.

Every time the remote sensor is powered up (for example after a change of batteries),
a random security code is transmitted and this code must be synchronized with the
base station to receive weather data. Thus if battery change happened on

transmitter side, then the receiver must be power up again to re-learn the
transmitter.

After the remote sensor is powered up, the sensor will transmit weather data every 8s
for 6 times. After this learning period is over, then the transmitter will transmit every
48s.

When the base station is powered up, a short beep will sound and all LCD segments
will light up for about 3 seconds before it enters into learning mode to learn the
sensors security code. After the learning mode, the base station will start the DCF

radio controlled time reception and the RCC search icon

will turn on. During the

RCC time reception period (maximum 10 minutes), no weather data will be transmitted
to avoid interference. If RCC signal can’t be found within1 minutes, the signal search
will be cancelled and will automatically resume every two hours until the signal is
successfully captured. Regular RF link will be established once RCC reception routine
is finished. Once the radio controlled time is received the DCF icon will be present
above the time

Note: DO NOT PRESS ANY KEY during the first 3 minut es l earning period. Af ter both
indoor and outdoor data are displayed you can place your remote sensor outdoors and
set your time (if no RCC reception is possible). If there is no temperature reading in
the indoor station, make sure the units are within range of each other or repeat the
battery installation procedure. If a key is pressed before the weather station receives
the temperature signal, you will need to follow the battery installation procedure again.

Please wait 10seconds before re-insert the battery again to make a proper reset
for both transmitter and receiver.

Note for Radio Controlled Time:

The time and date display is based on the signal provided by the highly accurate
government operated atomic clock. The base station will continue to scan for the radio
controlled time signal each day despite it being manually set. If reception has been
unsuccessful, then the radio controlled time icon will not appear but reception will still
be attempted continually. If reception has been successful, the received time and date
will overwrite the manually set time and date.

Note:
Please participate in the preservation of the environment by properly
disposing of all used-up batteries and accumulators at designated
disposal points. Never dispose of batteries in a fire as this may cause
explosion, risk of fire or leakage of dangerous chemicals and fumes

3.2 Mounting

1) Base station
With one foldable legs at the back of the unit, the base station can be placed onto any
flat surface or wall mounted at the desired location by the hanging holes also at the
back of the unit. It is important to check that the radio signal can be received before
permanently mounting any of the units

2) Remote sensor
Note: To achieve a true temperature reading, avoid mounting
remote sensor in direct sunlight. We recommend that you mount
the remote sensor on an outside North-facing wall; obstacles
such as walls, concrete, and large metal objects will reduce the
range.

To wall mount, use 3 screws to affix the wall bracket to the
desired wall, plug in the remote sensor to the bracket.
