•Do not immerse the unit in water.
•Do not clean the unit with abrasive or corrosive material.
•Do not subject the unit to excessive force, shock, dust, temper-
ature or humidity.
•Do not tamper with the unit’s internal components. Doing so
will invalidate the warranty on the unit and may cause unnec-
essary damage.
•Only use fresh batteries as specified in the instructions. Do not
mix new and old batteries as the old ones may leak.
•Always read the instructions thoroughly before operating the unit.
Warnings

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.)

Main Features: Remote Unit

1. Remove the screws on the battery compartment.
2. Select the channel number on the CHANNEL slide switch.
3. Select the temperature display unit on the °F/°C slide switch.
4. Insert two UM-4 or AAA-size batteries.
5. Replace the battery compartment door and secure the
screws.
Replace the batteries when the low-battery indicator of the par-
ticular channel lights up on the main unit.
Battery and Channel Installation: Remote Unit

Note: Once a channel is assigned to a unit, you can change it only
by removing the batteries and repeating the above procedure.
Battery Installation: Main Unit
1. Slide the battery compartment door open.
2. Insert two UM-3 or AA-size batteries.
3. Replace the battery compartment door.

4. Flip the table stand open and press the RESET button with
a blunt stylus. This ensures easier synchronization between
the transmission and reception of signals.
Replace the batteries when the indicator of the indoor tem-
perature lights up.
Getting Started
Once batteries are in place for the remote units, they will start
transmitting samplings at roughly 30-second intervals.
The main unit will also start receiving once batteries are
installed. The temperature of the selected channel will be dis-
played on the top line and the indoor temperature on the bot-
tom line. The main unit will automatically update its readings
at 30-second intervals. The temperature variance for the last
12 hours is automatically scanned on the trend chart.
Battery Installation: Main Unit

If no signals are received, blanks are displayed. Press CHANNEL
and MEMORY simultaneously to enforce another search. 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 the reading shown on the
respective remote unit.
Note: The remote temperature display on the main unit is deter-
mined by the selection made (°F or °C) on the main unit’s slide
switch. The remote sensors will automatically convert to the
selection made on the main unit.
Getting Started

The indoor temperature is shown on the bottom line of the dis-
play. Temperature readings, received from a remote sensor, are
displayed on the top line of the unit.
Press CHANNEL to change from one channel to the next.
If more than one remote sensor is being used, the unit can auto-
matically scan all three of the outdoor channels.
To use the automatic outdoor channel scanner function, press
and hold CHANNEL for about two seconds. The unit begins a
cycle of continuously rotating through the three channels.
Temperature readings from each site are displayed for approxi-
mately five seconds.
To stop the automatic scanning function, press CHANNEL again.
The scanning cycles will stop.
Checking Remote and Indoor Temperatures

The kinetic wave display on the channel icon indicates the status
of reception.
The unit is in searching mode
Temperature readings are
securely registered
No signals
If no readings are received from one particular channel for more
than two minutes, blanks are displayed until further readings are
successfully searched. To enforce an immediate search, press
CHANNEL and MEMORY simultaneously. Of course, no reading
will be shown if no remote unit is assigned to that channel.
The Cable Free™Indoor/Outdoor Thermometer is capable of
measuring temperatures within the -58°F (-50°C) and +158°F
(+70°C) range. If the temperature goes above or below these
temperatures, the display will show “HHH” or “LLL.”
Checking Remote and Indoor Temperatures

The maximum and minimum recorded indoor temperatures and
those of each channel are automatically stored in memory. To
display them:
1. Press CHANNEL to locate the desired channel.
2. Press MEMORY to rotate through the maximum (MAX), mini-
mum (MIN) and current temperatures. Indoor temperature
readings are displayed.
To clear the memory of a particular channel, press CHANNEL to
locate the desired channel. Press CLEAR. The MAX and MIN
memory for that channel will be erased. Note: It will also erase
the memory for the indoor temperatures.
Disconnected Signals
If, for no obvious reason, a particular channel display goes blank,
press CHANNEL and MEMORY to enforce an immediate search.
If that fails, ensure the remote unit for that channel remains in
place, ensure the transmission is within range and the path is
clear of obstacles and interference.
Maximum and Minimum Temperatures

The temperature variance for CHANNEL 1 for the past 12 hours
is automatically scanned on the screen in six equal columns. The
variance is represented in rows of degrees C above or below the
current temperature at 0 Hr (current time) and 0°C (no variance).
Ice Warning
The ice warning is selected on the ICE WARNING slide switch
located on the main unit and applies only to CHANNEL 1.
To activate the warning, slide the switch to ON. When the tem-
perature recorded at CHANNEL 1 falls to between 28.4°F (-2°C)
to 37.4°F (+3°C) a beeping alarm sounds and the ice warning
icon ❄and current outdoor temperature flash. The alarm
sounds every minute as long as the recorded temperature is
within alarm range. To stop the alarm, press any key or change
the channel. Display features continue to flash as a reminder that
the temperature remains within the ice warning range.
How to Read the Temperature Chart

To deactivate the ice warning function, slide the ICE WARNING
switch to OFF.
Table Stand and Wall Mount
To place the main unit on a flat surface, flip open the table
stand. Mount the unit on a wall using the recessed hole.
Ice Warning

The remote unit comes with a removable table stand and a wall-
mount holder.
Reset Button
The RESET button is used to enhance synchronization of signals
after battery replacement or when the unit malfunctions. Use a
blunt stylus to hold the RESET button down. All settings will
return to their default values.
