ALARM AND SNOOZE FUNCTION
When the alarm is active, it will go off at the set time. The display

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.

] indicator lights up.
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
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 & HUMIDITIES
The maximum and minimum recorded data will be automatically
stored in memory. To display them, press MEMORY to toggle
among the maximum, minimum and current data. The respective
MAX or MIN indicator will be displayed.
To clear the memory, hold down MEMORY for three seconds. The
maximum and minimum data 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.
