BEFORE YOU BEGIN
For best operation,
1. Assign different channels to different remote units.
2. Insert batteries for remote units before doing so for
the main unit.
3. Place the main unit as close as possible next to
the remote unit, reset the main unit after installing
batteries. This will ensure easier synchronization
between the transmission and receptionof signals.

4. Position the remote unit and main unit within effective
transmission range, which, in usual circumstances,
is up to 100 meters.
NOTE that the effective range is vastly affected by the
building materials and where the main and remote units
are positioned. Try various set-ups for best result.
Though the remote units are weather proof, they should
be placed away from direct sunlight, rain or snow.
BATTERY INSTALLATION: MAIN UNIT
1. Gently lift up the tab on the battery compartment
door.
2. Insert four UM-3 or “AA” size batteries.
3. Replace the battery compartment door.
BATTERY AND CHANNEL INSTALLATION:
REMOTE UNIT
The remote thermo-hygro sensor unit uses two (2) UM-4
or “AAA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
2. Select the channel number on the [CHANNEL] slide
switch.
3. Select the temperature display unit on the °C/°F slide
switch.
4. Insert the batteries strictly according to the polarities
shown therein.
5. Replace the battery compartment door and secure
its screws.
Replace the batteries when the low-battery indicator of
the particular channel lights up on the main unit. (Repeat
the steps described in section “BEFORE YOU BEGIN”)
NOTE that once a channel is assigned to a remote
unit, you can only change it by removing the batteries
or resetting the unit.

LOW BATTERY WARNING
When it is time to replace batteries, the respective
low-battery indicator will show up when the respective
channel is selected. The battery level of the main unit
will be shown on the indoor temperature when it is
running low.
HOW TO USE THE TABLE STAND OR WALL
MOUNTING
The main unit has a removable table stand, which when
connected, can support the unit on a flat surface. Or you
can remove the stand and mount the unit on a wall using
the recessed screw hole.
As for the remote unit, it comes with a wall-mount holder and
a removable stand. Use either to hold the unit in place.

THE RESET BUTTON
This button is only used when the unit is operating in an
unfavorable way or malfunctioning. Use a blunt stylus
to hold down the button. All settings will return to their
default values.
GETTING STARTED
Once batteries are placed in a given remote sensor
unit, it will start transmitting information at 40-second
intervals.
Also, for approximately a 3-minute duration, the main
unit will automatically search for signals once batteries
are installed. Upon successful reception, the individual
channel temperature reading will be displayed on the top

line and the respective humidity reading on the bottom
line. The main unit will automatically update its readings
at about 40-second intervals.
If no signals are received, blanks “---” will be displayed
and the kinetic wave icon will not show.
To force a signal search:
• Press and hold [CHANNEL] & [MEMORY] for 2
seconds to enforce a 3-minute search.
This is useful in synchronizing the transmission and
reception of the remote and main units.
Repeat this step whenever you find discrepancies
between the readings shown on the main unit and that
on the respective remote unit.
HOW TO CHECK REMOTE AND INDOOR
TEMPERATURE & HUMIDITY
Display of readings from a remote sensor or the main
unit is a one-step procedure. The remote sensor channel
or the main unit display is indicated in a box under the
kinetic-wave icon.

To display temperature / humidity readings from
the main unit:
• Press [CHANNEL] until a dot is displayed in the box
under the kinetic-wave.
To display temperature / humidity readings from a
remote sensor:
• Press [CHANNEL] until the appropriate remote sensor
channel is displayed in the box under the kinetic-wave.
DISCONNECTED SIGNALS
If without obvious reasons the display for a particular
channel goes blank, press [CHANNEL] & [MEMORY]
to enforce an immediate search.
If that fails, check:
1. The remote unit of that channel is still in place.
2. The batteries of both the remote unit and main unit.
Replace as necessary.
NOTE that when the temperature falls below freezing
point, the batteries of outdoor units will freeze, lowering
their voltage supply and the effective range.
3. The transmission is within range and path is clear
of obstacles and interference. Shorten the distance
when necessary.
TRANSMISSION COLLISION
Signals from other household devices, such as door
bells, home security systems and entry controls, may

interfere with those of this product and cause temporarily
reception failure. This is normal and does not affect the
general performance of the product. The transmission
and reception of temperature and humidity readings will
resume once the interference recedes.
HOW TO READ THE KINETIC WAVE DISPLAY
The kinetic wave display shows the signal receiving
status of the main unit. There are three possible forms:
The unit is in searching mode.
Transmission data are securely
registered.
No signal received in search
mode.
REMOTE SENSOR SCANNING
The unit can be set to automatically scan and display
readings from the remote sensors and indoor readings.
When the remote-sensor mode is active, the display will
show the readings from one channel for about 4-second
and then proceed to the next channel display.
To activate the remote-sensor scanning mode:
• Press and hold [CHANNEL] for 2-seconds.
To deactivate the remote-sensor scanning mode:
• Press either [CHANNEL], [MEMORY], [HI/LO], [ ],
[ON/OFF] (TEMP % RH AL)
THE COMFORT-LEVEL ICONS
The comfort level indicators COMFORT, WET or DRY

MAXIMUM AND MINIMUM TEMPERATURE
AND HUMIDITY
The maximum and minimum recorded temperature
and humidity readings will automatically be stored in
the memory.
To display the maximum and minimum display
memory:
1. Select the channel to be checked.
2. Press [memory] once to display the maximum
temperature and humidity and again the minimum
temperature and humidity. The respective indicators,
MAX or MIN will be displayed.
To clear the memory:
• Press and hold [MEMORY] for 2-seconds.
If you press [MEMORY] now, the maximum and minimum
recordings will have the same values as the current ones
until different readings are recorded.
HOW TO USE CHANNEL-1 TEMPERATURE/
HUMIDITY ALARM
Upper and lower temperature and humidity limits for
channel-1 can be set so that an alarm activates when
the limits are exceeded.
The high and low temperature and humidity displays are
selected by sequentially pressing HI/LO.
