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 reception of signals.
4. Position the remote sensor and main unit within effective transmission range, which, in usual circumstances, range of 100 feet (30 meters) under ideal conditions.

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 sensors are weather resistant, 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 (4) 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-3 or "AA" 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 showntherein.
   
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 low-battery indicator will be displayed for the selected channel.

HOW TO USE THE TABLE STAND OR WALL MOUNTING

THE RESET BUTTON

This button is used when the unit is operating in an unfavorable way or malfunctioning. To return all user programmed settings to their original factory values, press [ RESET ] by using a blunt stylus to hold down the button.

GETTING STARTED

Once batteries are placed in a given remote sensor unit, it will start transmitting information at 40-second intervals.

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 second line and the respective humidity reading on the third 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] &[MEM] 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 reading 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 onestep procedure. The remote sensor channel or the main unit display is indicated in a box under the kinetic-wave icon.

Kinetic-wave Icon
Designated Display	Indoor Display	Remote Display Channel 1	Remote Display Channel 2	Remote Display Channel 3

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] & [MEM] 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 asnecessary.
   Note that when the temperature falls below freezing point, the batteries of outdoor units will freeze, which will lower their voltage supply and the effective range.
3. The transmission is within range and path is clear of obstaclesand 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 temporary 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 scanning 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], [MEM],

COMFORT LEVEL INDICATORS

The comfort level indicators COM, WET or DRY will tell you if the curent environment is comfortable, too wet or too dry.

The comfort indicator will appear on the display when the following conditions are satisfied:

Indicator displays on the unit	Temperature Range	Humidity Range	Shows that the Current Environment
COM	20°C to 25°C (68°F to 77°F)	40%RH- 70%RH	Ideal range for both relative humidity and temperature
WET	-5°C -+ 50°C (23°F - 122°F)	OVER- 70%RH	Contains excess moisture.
DRY	-5°C -+ 50°C (23°F - 122°F)	Below 70%RH	Contains inadequate moisture
No Indicator	Less than 20°C( 68°F) or More than 25°C (77°F)	40%RH to 70%RH	No comment

TEMPERATURE, HUMIDITY & PRESSURE TREND INDICATORS

The temperature-trend, humidity-trend and pressure-trend indicators show the trends of collected readings. Arrows indicate a rising, steady or falling trend.

Note
If the reading goes above or below the measuring range of the main unit or the remote unit ( stated in specification), the display will show "HHH" or "LLL".

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 [MEM] once to display the maximum temperature and humidity and press [MEM] again to display minimum temperature and humidity. The respective indicators, MAX or MIN will be displayed.

To clear the memory:

• Press and hold [MEM] for 2seconds.

If you press [MEM] 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].

   If this is the first time you set the limits, the lower limit will start from -50°C (-58°F) and the upper limit +70°C (158°F). Otherwise, the reading will start from the temperature last selected.
   The humidity range is from 2% to 98%.
   If this is the first time you set the limits, the lower limit will start from 2% and the upper limit 98%. Otherwise, the reading will start from the humidity last selected.
3. Repeat the steps to set the upper temperature and humidity setting and the lower temperature and humidity settings.
4. When finished, press [HI/LO] to set another limit or wait 16 seconds and the unit will automatically return to the normal display. The respective HI, LO or both indicators will be displayed to signify the status of the alarm.

If a channel other than channel-1 is selected, the display will switch to channel-1 and flash when the alarm activates. If left untouched, the alarm will activate for 1 minute. Press either [CHANNEL], [MEM], to momentarily stop the alarm. The alarm will activate again if the limit continues to exceed the set limit.

Note
