Meade Instruments TE278W - Manual (Page 5)

A. LED INDICATOR
• Flashes once when the remote sensor transmits a reading to the main unit.
• Flashes twice when battery power is low.
B. BATTERY COMPARTMENT
• Requires two AA-size batteries
C. RESET
• Resets all previous settings
D. CHANNEL SWITCH
• Selects the desired channel -1, 2 or 3
E. WALL-MOUNT RECESSED OPENING
• Keeps the remote sensor on the wall
BEFORE YOU BEGIN
• We recommend using alkaline batteries for the remote sensor and the main unit. If outdoor
temperatures regularly fall below 32°F (0°C), we recommend using lithium batteries.
• Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct
power requirements).
• ALWAYS install batteries in the remote sensor before the main unit.
• Insert batteries before first use, matching the polarity as shown in the battery compartment.
• Press RESET after each battery change with a paper clip or similar tool.
• During an initial setup, place the main unit close to the remote sensor.
• After reception is established (the remote temperature will appear on the main unit’s display),
position the remote sensor and the main unit within the effective transmission range of
160 feet (50 meters).
• The remote sensor can be placed indoors or outdoors, depending on the area where the
temperature is intended to be measured. If you intend measuring outdoor elements, place
remote sensor outdoors
• The main unit must be placed indoors.
NOTE:
1. Avoid pressing any buttons on the main unit before the remote readings are displayed.
2. The effective operating range may be influenced by the surrounding building materials and
how the receiver and transmitter are positioned.
3. Place the remote sensor so that it faces the main unit (receiver), minimizing obstructions
such as doors, walls, and furniture.
4. Though the remote sensors are weather-resistant, they should be placed away from direct
sunlight, rain or snow. The best suggested location for the remote sensor for outdoors is
under the eave on the north side of the building.
NOTE: When the temperature falls below freezing point 32°F (0°C), battery voltage will
drop which may result in reduced the transmission range. For optimum performance in
cold conditions, we recommend using lithium batteries.
