SIGNAL DETECTION
SUCCESSFUL RECEPTION
Losing synchronization or the Wireless Thermometer
it the base unit displayed a proper outdoor temperature in the past but now displays blank
the outdoor unit and the main unit may have lost synchronization. it this occurs, press the
RE-SYNC button ot the main unit, The main unit will attempt outdoor temperature reception
for another 6 minutes and reinitiate synchronization with the outdoor unit. It the outdoor
temperature cannot be received. check,
1. The distance at the main unit or outdoor unit should be at least 3-4 teat away lrorn any
interlering sources such as computer monitors or TV sets.
2. Avoid placing the main unit onto or In the immediate proximity ct metal window trames,
3. Using other electrical products such as headphones or speaker operating on the same
signal irequency ( 433MHZ ) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operation on the 433MHz signal trequenoy can also
cause interterence.
Note: When the 433MH1 signals is received correctly, do not re-open the battery cover at
either the outdoor unit or the main unit, as the batteries may spring tree from the contacts and
force a false reset. Should this happen accidentally then reset both unit otherwise transmis-
sion problems may occur.
P. 6
The maximum transmission range is 150 feet trom the outdoor unit to the main unit ( in open
space ). However, this depends on the surrounding environment and interference levels. The
temperature signal travels in a straight line trom the outdoor unit to the clock. The signal will
not curve around blocking object. It no reception is possible despite the observation ot these
lactors, all unit have to be reset.
Interference
Signals trom other household devices. such as entry controls, door bells and home security
systems. may temporarily intertere with the units and cause reception lailure. This is normal
and does not affect the general pertormance oi the product. The transmission and reception at
temperature reading will resume once the interference has stopped
Trouble Shooting I FAQ ( Frequent Ask Question )
There is no outdoor temperature shown on the unit?
A : Press the RE-SYNC button on the main unit and the outdoor temperature will shown
within minutes if no temperature Is shown after 6 minutes of FIE-SYNC button pressed.
the outdoor unit is either too lar away ol there is some interlerence between the outdoor
and main unit. Bring the outdoor unit to the main unit and rte-synchronizes. Then move the
outdoor unit to a new location closer and in direct line with the main unit,
The outdoor temperature is reading 105°F when the temperature is in the 60°F
A : The outdoor unit is in direct sunlight. Move it to a shaded protected area.
Care at Your Clock
- Avoid exposing your clock to extreme temperatures, water or severe shock.
- Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents,
- Do not subject the clock to excessive force, shock. dust. temperature or humidity. Any at
these conditions may shorten the tits at the clock.
- Do not tamper with any oi the internal components or this clock. This will invalidate the
Warranty and may cause damage.
Correct Usage ot the Batteries
- Use 4 new AA batteries
- Do not mix standard and rechargeable batteries
- Do not mix new and old batteries
- When the low battery mark “ B " appears on the display, replace all batteries With new ones,
when the low battery mark “ 8 " appears on the OUTDOOR temperature field, replace all
batteries oi outdoor unit with new ones.
