Quick Start
Battery Installation
Remote Units:
•Unscrew battery compartment cover for remote units first.
•Designate a channel number (1, 2, 3) for each remote on the
Channel Slide Switch; choose ˚F or ˚C temperature display
unit on the ˚F/˚C Switch.
•Insert two AAA (UM-4) batteries (included) into each battery
compartment as specified. Ensure proper polarities are main-
tained; replace cover.
Main Unit:
1. Slide open battery compartment door.
2. Insert two AA (UM-3) batteries (included). Ensure proper
polarities are maintained; replace door.
Checking Temperatures:
1. Using either the table stand or wall mount feature, set the
main and remote units within an effective range of 110
yards. Although the remote units are weatherproof, they
should be located away from direct sunlight, rain or snow.
2. Once batteries are installed, the main unit will start receiving
Quick Start
temperature samplings at roughly 30-second intervals from
the three remote units. If no signal is received, blanks will be
displayed. Press the main unit’s CHANNEL and MEMORY
simultaneously to enforce another search, or to synchronize
the transmission and reception of the remote and main units
if you find discrepancies in the temperatures shown.
3. To view one remote unit’s temperature display, press CHAN-
NEL to change from one to the next.
4. To scan all three remote units with one touch, press and hold
CHANNEL for about 2 seconds and view all three tempera-
tures for 5 seconds each. Press CHANNEL again to stop the
scanning function.
5. To display the maximum and minimum temperatures stored
in each remote unit’s memory, press CHANNEL for the
desired channel, then press MEMORY to rotate through the
maximum, minimum and current temperatures.
6. To clear the memory of a particular channel, press CHANNEL
to locate the desired channel, then press CLEAR to erase the
stored maximum and minimum temperatures. (Now, if you
press MEMORY, these settings will have the same value as the
current temperature until different readings are recorded.)
