[. . . ] °C/°F SLIDE SWITCH Selects between degrees Centigrade (°C) and Fahrenheit (°F) K. BATTERY COMPARTMENT Accommodates two UM-3 or AA-size batteries J M H I 2 L. LOW BATTERY INDICATOR - Appears on the 1st Line indicates the battery power of the remote sensor in display is low - Appears on the 3rd Line indicates the battery power of the main unit is low A. LCD DISPLAY Displays the current temperature monitored by the remote unit B. [. . . ] 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 that on the respective remote unit. HOW TO CHECK 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. GETTING STARTED Once batteries are in place for the remote units, they will start transmitting samplings roughly at 30-second intervals. The temperature of the selected channel will be displayed on the top line and the indoor temperature on the bottom line. The main unit will automatically update its readings at 30-second intervals. The temperature variance for the last 12 hours is automatically 5 GB GB 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 2 seconds. The unit will begin a cycle of continuously rotating through the three channels. Temperature readings from each site will be displayed for approximately 5 seconds. The kinetic wave display on the channel icon indicates the status of reception. MAXIMUM AND MINIMUM TEMPERATURES The maximum and minimum recorded indoor temperatures and those of each channel will be automatically stored in memory. Press [MEMORY] to rotate through the maximum [MAX], minimum [MIN] and current temperatures. Press [CLEAR], the MAX and MIN memory for that channel will be erased. If you press [MEMORY] now, the maximum and minimum temperatures will have the same values as the current ones until different readings are recorded. The unit is in searching mode. No signals. DISCONNECTED SIGNALS If no readings are received from one particular channel for more than two minutes, blanks will be displayed until further readings are successfully searched. You can wait for a little while or press [CHANNEL] and [MEMORY] simultaneously to enforce an immediate search. Of course no reading will be shown if no remote unit is assigned to that channel. The JTR-168LR is capable of measuring temperatures within the -50°C (-58°F) and +70°C (+158°F) range. If the temperature goes above or below that, the display will show "HHH" or "LLL". 6 If without obvious reasons the display for a particular channel goes blank, press [CHANNEL] and [MEMORY] to enforce an immediate search. If that fails, check if the remote unit of that channel is still in place. Make sure the transmission is within range and path is clear of obstacles and interference. HOW TO READ THE TEMPERATURE TREND CHART The temperature variance for CHANNEL 1 for the past 12 hours is automatically scanned on the screen in six equal columns. [. . . ] Such treatment may result in malfunction, a shorter electronic life span, damaged batteries, or distorted parts. Doing so will terminate the unit's warranty and may cause damage. Read this instruction manual thoroughly before operating the unit.
