Using 6 foot Temperature Probe
Your wireless thermometer is equipped with a 6 feet cord temperature probe for measuring water, soil, or
temperatures below 32°F.
• Open the rubber covers of the hole at the side of the remote sensor and insert the probe plug completely.
• If the outside temperature is extremely low (below 32°F) extend the 6 feet probe cord, leave probe sensor
outside, and keep the remote sensor unit inside to avoid freezing the batteries.
• For measuring temperature in a freezer, keep sensor outside of freezer and run probe inside, taking care to
secure the wire to avoid damage from the door.. An alarm can also be set to warn of high temperature.
• The probe can be used at all times if desired (for air temperature) as it has a greater range of temperature.
Installation of Remote Sensor(s)
It is recommended to place the sensor on the North side of a house to avoid direct sunlight. Locating remote
sensor in clear open area can attain a maximum 100 ft. (30 meters) transmission distance. The actual
transmission distance can be reduced by walls between the remote sensor(s) and the receiving unit. The remote
sensor(s) can be hung on a flat wall by means of a screw or tape, or the bracket has a folding stand for use on a
horizontal surface, such as a table.

Remote Channel Auto Scroll

upper/lower icon will flash.
Battery Replacement
A “ ” low batter icon will appear on the display of the receiving unit when the batteries of the receiving unit
and remote sensor(s) need to be replaced (the sensor also has a low battery indicator on its LCD). For replacing
batteries always use new batteries, and follow instructions carefully (replace all batteries at this time).
Precautions
Do not subject the units to excessive exposure to direct sunlight. The remote sensor is splash proof design, but
should not be immersed in water or exposed to heavy rain. Do not clean the units with abrasive or corrosive
compound or subject the units to excessive shock, dust, temperature or humidity. Do not tamper with these
units’ internal components. Doing so will invalidate the warranty on the unit.
Troubleshooting
Lost Signal (“--.-”): If unit has been in operation successfully, check to be sure remote is still functioning (LCD
is lit, with no low battery signal). Position sensor and display closer, or limit number of walls that lie in a
straight path between remote and sensor. Press and hold the “-/Hold Seek” button until the display beeps once
(display will search for the signal and beep upon receiving). If this does not work, simply remove all batteries
and replace with new batteries, closely following the instructions.
Incorrect Temperature readings: Be sure all units are away from sources of heat or cold, such as vents,
radiators, and lights (including sunlight). Be sure probe is completely plugged or unplugged from sensor. Allow
several minutes for units to adjust to a new temperature (such as bringing in from outside). The accuracy of
temperature measurement is +/- 2°F, and keep in mind other thermometers may be inaccurate.
Other issues: If other issues arise, please remove all batteries and replace with new ones, carefully following
the instructions. On occasion, as with all electronics, undesired occurrences take place. Removing the batteries
and replacing with new ones will solve those problems. Your Speedtech Tempmate comes with particular
testing sequences that can be activated with certain combinations of button presses. These combinations are not
required for regular use, but can cause the units to appear to malfunction, and removing all batteries will solve
these issues. You may refer to our website for more detailed explanations and further troubleshooting.
