Do not mix new and old batteries as the old ones may leak. •Always read the instructions thoroughly before operating the unit.
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 maintained; replace cover. Main Unit: 1. Slide open battery compartment door. 2. Insert two AA (UM-3) batteries (included).
Quick Start 3. 4. 5. 6. 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. To view one remote unit’s temperature display, press CHANNEL to change from one to the next.

Battery and Channel Installation: Remote Unit 1. 2. 3. 4. 5. Remove the screws on the battery compartment. Select the channel number on the CHANNEL slide switch. Select the temperature display unit on the °F/°C slide switch. Insert two UM-4 or AAA-size batteries. Replace the battery compartment door and secure the screws. Replace the batteries when the low-battery indicator of the particular 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.
Battery Installation: Main Unit 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 temperature 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.
Getting Started 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 determined by the selection made (°F or °C) on the main unit’s slide switch.
Checking Remote and Indoor Temperatures The indoor temperature is shown on the bottom line of the display. 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 automatically scan all three of the outdoor channels. To use the automatic outdoor channel scanner function, press and hold CHANNEL for about two seconds.
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.
Maximum and Minimum 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), minimum (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.
How to Read the Temperature Chart 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.
Ice Warning 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.
