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 SEARCH for 3 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.
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.
If no readings are received form one particular channel for more than 15
minutes, blanks“---”will be displayed until further readings are
successfully searched. Check the remote sensor to ensure that it is secure
and the channel has been selected. Optionally, press SEARCH button to
enforce a search.

●Press and hold MEM/CLEAR now, the maximum and
minimum temperatures will have the same values as the
current ones until different readings are recorded.
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.
To set a high or low tem pe ra tu re or hu mi di ty a la rm :

3. The transmission is within range and path is clear of obstacles
and interference. Shorten the distance when necessary.
Note:
The temperature range is from -50 ℃ (-58 ℉ ) to 70 ℃ (158 ℉ ).
If this is the first time you set the limits, the lower limit will start
from -50 ℃ (-58 ℉ ) and the upper limit 70 ℃ (158 ℉ ).
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.
If in another channel other than channel one is selected, when the
alarm activates the display will switch to channel-1 and the display
will flash. If left untouched, the alarm will activate for a 1-minite.

Note: If a second limit is passed while an alarm is active, the
first alarm will complete its 1-minute cycle and the alarm will
continue to activate for a second minute to indicate that a
second limits has been surpassed.
Note that when the temperature falls below freezing point, the
batteries of outdoor units will freeze, lowering their voltage
supply and the effective range.
