[. . . ] Multi-Channel Indoor & Outdoor Thermometer with Cable FreeTM Sensor & Radio ControlledTM Clock MODEL: RMR166 USER'S MANUAL MAIN FEATURES CABLE FREE A B C CHANNEL F PM C E INTRODUCTION Thank you for purchasing the RMR-166 Multi-Channel IndoorOutdoor Thermometer with 433MHz Cable FreeTM temperature sensor and Radio ControlledTM calendar clock. This basic package consists of the main temperature and calendar clock unit and a wireless remote temperature sensor, model THN138. The main unit can support up to three Cable FreeTM remote sensors. Additional remote sensors are available. [. . . ] Press [CHANNEL] to sequence through the channels. The temperature displayed will be the data for that specific channel and remote sensor. A kinetic wave will be displayed below the channel number indicating the quality of signal reception from that particular 6 MAXIMUM & MINIMUM TEMPERATURES The maximum and minimum recorded indoor temperatures and those of each remote sensor are automatically stored in memory. To display the indoor recorded temperatures, press [MEMORY] once to display the maximum (MAX) temperature and once again for the minimum (MIN) temperature. To display temperature data from a remote sensor, select the channel of that remote sensor. Press [MEMORY] once to display the maximum (MAX) temperature and once again for the minimum (MIN) temperature. To clear the memory, hold down [MEMORY] for two seconds. The maximum and minimum recorded temperatures will be erased. When the memory has been cleared, the maximum and minimum temperatures will be identical to the current temperature until new readings are recorded. NOTE: When the temperature falls below freezing point, the batteries in the outdoor positioned sensor will freeze, lowering the battery voltage supply and the effective range. WIRELESS TRANSMISSION Signals from other household devices including door bells, home security systems and entry controls, may interfere with those of this product and cause temporary reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature readings will resume once the interference ends. The success of wireless transmission of data may vary and is directly related to where the remote sensor is placed and the environmental factors of that location. Should there be difficulty in data transmission, verify: 1. The low battery warning icon is not displayed for the main unit or the remote sensor. The remote sensor has been placed within the stated effective range (21 - 32 yards) of the main unit. That there is no obstacle (like a transmission tower) or environmental reason (such as a steep hill) which is causing the interference or blockage between the remote sensor and the main unit. If the difficulty continues, reposition the remote sensor to a different location and/or closer to the main unit. INTERRUPTED SIGNALS If the display for a particular channel goes blank on the main unit, press [CHANNEL] and [MEMORY] at the same time for about 30-seconds to trigger a signal search between the remote sensor and the main unit. If that does not reactivate signal reception, verify: 1. The low battery warning icon for both the remote sensor and main unit are not displayed. The remote sensor is within the effective transmission range (approximately 21 - 32 yards) to the main unit and that the transmission path is clear of obstacles and interference. Shorten the distance between the remote sensor and the main unit if necessary. 7 NOTE ON °C AND °F Using the [Temperature Slide Switch], select °C for degrees in GB GB Centigrade or °F for Fahrenheit for both the remote sensor and the main unit. [. . . ] 10 PRECAUTIONS This product has been designed and manufactured to give you years of service if it is carefully handled. Do not clean the unit with abrasive or corrosive materials. They may scratch the plastic parts and corrode the electronic circuit. Do not subject the unit to excessive force, shock, dust, temperature or humidity, which may result in malfunction, shortened electronic life span, damaged battery and distorted parts. [. . . ]
