CHANNEL SCAN FUNCTION

Press and hold CHANNEL button for 3 seconds to enter channel
scan function. The readings of each channel will be displayed one
by one for 4 seconds automatically. Press any key to stop the scan
function.

NOTE ON REMOTE TEMPERATURE

& HUMIDITY

Once batteries are in place for the remote unit, it will start transmit-
ting samplings at 39-43-second intervals.

If no signals are received when the remote  temperature and humidity
is selected, blanks will be displayed. Press and hold the CHANNEL
button to enforce a search. This is useful in synchronizing the
transmission and reception of the remote and main units.

If that fails, check if the remote unit is still in place. Make sure the
transmission is within range and path is clear of obstacles and
interference.

Repeat this procedure whenever you find discrepancies between
the reading shown on the main unit and the remote unit.

NOTE ON °C AND °F

The outdoor temperature display on the main unit is dominated by
the selection on the °C/°F slide switch of the main unit. Whatever
the display unit of the remote sensor is, it will only apply to the
remote sensor itself and the temperature will be automatically
converted to the chosen one of the main unit.

MAXIMUM AND MINIMUM

TEMPERATURES

The maximum and minimum recorded temperatures will be auto-
matically stored in memory. To display them, press MEMORY to
toggle among the maximum, minimum and current temperatures.
The respective MAX or MIN indicator will be displayed.

To clear the memory, hold down MEMORY for three seconds. The
maximum and minimum temperatures will be erased. If you press
MEMORY now, the maximum and minimum temperatures and
humidities will have the same values as the current one until
different readings are recorded.

TEMPERATURE AND HUMIDITY TREND

The temperature and humidity trend indicator shows the trend of
temperature changes for the last few minutes. Three trends, rising,
steady and falling, will be shown.

ALARM AND SNOOZE FUNCTION

When the alarm is active, it will go off at the set time. The display
will light up for five seconds with the ALARM ON icon flashing.

The crescendo function allows the alarm to start off gently and step
up its intensity in three steps. Without interruption, the alarm will
go off for 2 minutes.

To stop the alarm, press any button. If the SNOOZE/LIGHT
button is pressed, the SNOOZE  function will be triggered. The
alarm will stop and the bell icon blinks for about eight minutes
before going off again.

PRE-ALARM FUNCTION FOR

CHANNEL 1 REMOTE SENSOR

The alarm function also has a pre-alarm feature which can alert the
user before the preset alarm time when weather condition changes.
This pre-alarm function applies to Channel 1 Remote Sensor only.

To enable this function, first activate the alarm function. Then enter
the Pre-Alarm mode by pressing the ALARM button twice.  The
“Pre-Al” icon will be displayed. Press and hold the ALARM button
for 3 seconds to set the operating time interval for this pre-alarm
function.  Use the UP or DOWN button to select from the 4 time-
intervals: 15, 30, 45 or 60 minutes.  Press the ALARM button to
confirm and exit.  The pre-alarm function will be enabled
automatically which is indicated by the appearance of the [ 

  ]

symbol.

To disable this function, press the DOWN button in the Pre Alarm
mode.  The [ 

 ] symbol will disappear to indicate such disable.

The pre-alarm will operate during the selected time interval before
the daily alarm time.  For example, if the daily alarm is set to go off
at 7:00 am and the pre-alarm operating time interval is set to 45
minutes, the pre-alarm will start to operate at 6:15 am (45 minutes
before 7:00 am).

During the pre-alarm operating period, if the temperature recorded
at Channel 1 remote sensor falls to or below 2.0ºC, the pre-alarm
will be triggered.  The Pre-Alarm icon will flash and the backlight
will be turned on for 5 seconds.  An alarm sound will also go off for
2 minutes as that of the daily alarm and the snooze function will
also be activated if the SNOOZE/LIGHT button is pressed.

Note: The daily alarm will NOT function until the next day if the
pre-alarm has been triggered beforehand. Deactivation of the
alarm function will disable the pre-alarm feature automatically.

HOW TO CHECK INDOOR AND OUTDOOR-

REMOTE TEMPERATURES & HUMIDITIES

To display indoor temperatures and humidities, press the
CHANNEL button until the [ 

 ] indicator lights up.

To display outdoor-remote temperatures and humidities, press the
CHANNEL  button to scroll through the readings from up to 3
remote sensors.

The temperature can be shown in Centigrade (°C) or Fahrenheit
(°F). It is selected on the °C/°F slide switch. Slide the switch to °C
for Centigrade or °F for Fahrenheit.

If the readings go above or below the specified range, the display
will show flashing “HHH” or “LLL”.
