READ THIS BEFORE YOU BEGIN
For the best operation:
1. Insert batteries for remote transmitter(s) first, and then the receiver
2. Place the receiver and remote transmitter(s) close together. This will ensure that the receiver can
synchronize with remote transmitter(s).
3. Place the remote transmitter(s) within effective transmission range.
* Although remote transmitter are weather proof, it is recommended to place it away from direct sunlight, rain or snow. This will help to
make measurement more accurate.
# The building materials and where the receiver and remote transmitter are positioned vastly affect the effective range. Try various set-ups
for best result.

GETTING STARTED
Warning: Any changes or modifications made to this equipment not expressly approved by
Mandolyn Electronic Ltd. may void the FCC authorization to operate this equipment.
USING THE THERMOMETER FOR THE FIRST TIME
! Set up the transmitter for use first so that the base station can receive a signal immediately.
Step 1: Using the transmitter for the first time
1. Open the battery compartment of the transmitter.
2. Insert 2xAA batteries included with purchase. Ensure correct polarity +/- as shown in the compartment.
Replace the cover.
3. Once the batteries are inserted correctly, the display will show “01H” for House Code, and the range of House
Code is from “01” to “15”, change the House Code by pressing C/F key and SET key to confir m. Make sure all
transmitters in your system are set to the same House Code.
Note: It is highly recommended to change to different House Code if interference is experienced.
4. After the House Co de is set, it goes to Channel setting, and there is a number 1 is flashing at the left-hand side
of LCD. Same as House Code setting, pressing C/F key to change the Channel and SET key to confirm. After this,
it will go to Temp unit setting.
Note: if there are more than 1 transmitters need to be connect to same receiver, then the House Code of all the
transmitter should be the same but the Channel number is different.
5. The temp display will be flashing after the Channel, and pressing C/F to toggle between C and F display. Then, it
can leave it and the transmitter will transmit the 1
st
signal automatically . If pressing SET key, then will go back to the
house code setting again.
6. Once setup of remote transmitter is completed, it will start transmission in one minute interval.
*The setting is confirmed automatically if it is in idle for 8 seconds.
*Use different house code if your weather station detected other signals from neighboring sources
*Factory default: house code=01 and channel=01
Step 2: Setting the base st ation
1. Remove battery cover and insert 2xAA size batteries, ensure correct polarity + / - as shown in the compartment,
replace the cover.

SYNCHRONIZE
Automatic Learn Function:
1. After inserting the batteries, the indoor temperature is displayed.The base station now tries to pick up signals
from sensors for 3 minutes.If no signal is detected, bars are shown on the display.
2. As soon as the base station has detected a sensor signal, the display then shows the temperature value
received from the sensor.
3. If reception is lost before the time can be set, then place the base station, which has better reception, such as,
near a window. Please re-do the above procedure to restart the search for signals from sensors.
*If the signals are not received within this 3 minutes, the outside temperature will show ”- - -“ , during this time, bringing the unit close
together or try different location and restart the auto learning function by removing and replacing the batteries for receiver.
Manual-Learn function (Searching for Remote Signals):
If a new transmitter is added or if signal is lost (outdoor display blinking), learn function must be executed again.
1. Press the “Channel” button and hold for 3 seconds. The Outdoor symbol starts to flash and the base station
confirms your setting by sounding an audible tone.
2. As soon as the base station has detected a sensor signal, the ba se statio n display then shows the temp erature
value received from the sensor .
3. It is recommended to place the transmitter and receiver together during synchronization process. If the green
indicator of transmitter flashes and the data is shown onto the receiver, this process is considered to be
successful; otherwise, it is recommended to repeat this process.
CLOCK/DATE SETTING
Clock / Date / Month / Year Setting:
1. Hold “Mode” key to go into Clock Setting Mode;
2. Press “MAX / +” key to increase hour digit and “MIN / -” key to increase min digit;
3. Press “Mode” key to go into Date Setting Mode;
4. Press “MAX / +” key to increase Date digit and “MIN / -” key to increase Month digit;
5. Press “Mode” key to go into Year Setting Mode;
6. Press “MAX / +” key to increment and “MIN / -” key to decrease Year digit;
7. Press “Mode” key to cease the setting and back to clock display
8. Press “Mode” at clock display mode to change between 12/24 hr display

TEMPERAT URE DISPLAY
Check Local Temperature:
1. After insert batteries, indoor temperat ure will display
Check Remote Temperature:
2. Press “CHANNEL” to toggle between channel 1,2,3 and 4
o
C or oF T emperature Display:
3. Toggle between
o
C and oF by pressing “C / F”
Max and Min Temperature Display:
4. Press “MAX / + “ to display maximum temperature
5. Press “MIN / -” to display minimum temperature
T emperature Trend Indicator:
The trend indicator shows the trend of temperature determined by the particular sensor in the
past half-hour interval
Arrow Indicator
Trend Rising Steady Falling
LOW BATTE RY INDICATION
Transmitter:
1. When the batteries are running out, low battery symbol will display onto the receiver as well as transmitter.
It will directly degrade the performance, for example:
- the LCD display is faint ;
- may cause the transmission range to be limited and lose the data with receiver
2. You will need 2 x AA batteries and re-perform the setting of transmitter
Base Station:
1. When the batteries are running out , low battery symbol “
” will display under the temperature digit.
It will directly lower the receiver’s performance, for example:
- the LCD display is faint ;
- may cause the transmission range to be limited and lose the data from remote transmitter(s)
2. You will need 2 x AA batteries for the base station
- Changing the batteries in the base station will cause all settings to be erased
TROUBLESHOOTING
1. Base station is no longer receiving remote sensor
signals or display
2. Operation is not normal or certain functions do not
perform
Solution
1. -Repeat the learning procedures
-Temperature may be below -30
o
C
-Batteries in remote sensor may need changing
-Move remote sensor closer to the receiver
-Make sure remote sensor is away from sources of
electrical disturbance
2. Device requires reset. Reset the device by replacing
new batteries in both transmitters and receiver
