GB DISCONNECTED SIGNALS If without obvious reason the display for the main unit goes blank or " " are displayed, press and hold [CHANNEL] to enforce an immediate search. If that fails, check: - All weather instruments are still in place. - The batteries of the main unit and individual weather instruments are still good. Replace them if necessary. Press and hold [CHANNEL] to enforce an immediate search afterwards. - The transmission is within range and path is cleared of obstacles and interference. Shorten the distance if necessary. Then press and hold [CHANNEL] again. The main unit will start searching for all previously locked weather instruments. If you want to add an new sensor, press the reset button on the new sensor and then press channel to enforce the main unit to search. Note: 1. Do not reset the sensors after the main unit has locked those sensors, otherwise the main unit will no longer receive the signal from those sensors. 2. If you have disconnected signals, you cannot clear the memory. THE RESET BUTTON This button is only used when the system is operating in an unfavorable way or malfunctioning. Use a blunt stylus to hold down the button. The main unit will return to all default settings and start searching for signals again. Before resetting the main unit, you should do the same for all weather instruments to ensure correct transmission and reception of signals. Then press reset on the main unit.

Here are a few product care instructions: 1. Do not immerse the unit in water. If the unit comes in contact with water, dry it immediately with a soft lint-free cloth. 2. Do not clean the unit with abrasive or corrosive materials. Abrasive cleaning agents may scratch the plastic parts and corrode the electronic circuit. 3. Do not subject the unit to excessive: force, shock, dust, temperature, or humidity. Such treatment may result in malfunction, a shorter electronic life span, damaged batteries, or distorted parts. 4. Do not tamper with the unit's internal components. Doing so will terminate the unit's warranty and may cause damage. The unit contains no user-serviceable parts. 5. Only use new batteries as specified in this instruction manual. Do not mix new and old batteries as the old batteries may leak. 6. Read this instruction manual thoroughly before operating the unit.
