If no signals are received, blanks “ ” will be displayed and
the kinetic wave icon will show “ ”. Press CHANNEL and MEM
simultaneously to enforce another search for about 30 seconds.
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
INDOORS TEMPERATURES
The indoors temperature is shown on the bottom line of the
display.
As for the remote sites or channels, press CHANNEL to go from one
channel to another. The kinetic wave display on the channel number
indicates the reception of that particular channel is in good order.
DISCONNECTED SIGNALS
If without obvious resasons the display for a particular channel
goes blank “ ”, press CHANNEL and MEM to enforce an
immediate search. If this fails, check the following.
1. The remote unit of that channel is still in place.
2. The batteries of both the remote unit and main unit and replace
as necessary.
Note : When the temperature falls befow freezing point, the
batteries of outdoor units will freeze, lowering their voltage
supply and the effective range.
3. The transmission is within range and the path is clear of obstacles
and interference. Shorten the distance when necessary.
TEMPERATURE TREND
The temperature trend indicator on the screen shows the trend of
readings collected at that particular remote site. Three trends,
rising, steady and falling, will be shown.
If the temperature goes above or below than the temperature meas-
uring range of the main unit or the remote unit ( stated in specifi-
cation), the display will show “HHH” or “LLL”.
