3. The transmission is within range and path is clear of
obstacles and interference. Shorten the distance when
necessary.
l) 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 readings
will resume once the interference recedes.
m) Heat Index
The heat index is based on the temperature and
humidity measurements of the channel 1 sensor.
The heat index is an index that combines air
temperature and dew point in an attempt to determine
the human-perceived equivalent temperature — how hot
it feels, termed the "felt air temperature". The human
body normally cools itself by perspiration, or sweating,
which evaporates and carries heat away from the body.
However, when the relative humidity is high the
evaporation rate is reduced, so heat is removed from the
body at a lower rate causing it to retain more heat than
it would in dry air. Measurements have been taken
based on subjective descriptions of how hot subjects
feel for a given temperature and humidity, allowing an
index to be made which corresponds a temperature and
humidity combination to a higher temperature in dry air.
The heat index contains average assumptions about the
human body mass and height, clothing, and the wind
speed.
b) Setting up the Location Data
i) In Sunrise/Sunset Mode, press and hold SET to
enter location data setup.

6. SUNRISE AND SUNSET MODE
Important: All operations described in here are to be
made in the Sunrise/Sunse mode
The main console unit computes the sunrise and sunset
times from the user-configured location data. This
includes the longitudes, latitude, time zone and DST
(Daylight Saving Time). Choosing a suitable city code
for your location will automatically generate the correct
values for the location data.
Should you wish to input your own location data or if a
suitable city code could not be found, choose “USR” as
the city code during setup. A searching function is also
available, which allows the sunrise/sunset times for
different dates to be viewed.
a) Accessing Sunrise/Sunset Mode
From the main console unit: Press “+” or “-” until the
sunrise and sunset icons on the lower left of the
