Sensor Long Valve & Short Valve FCC ID: GQ4-67T Canada IC: 1470A-48T Model #: 209624-125, -126 GENERAL DESCRIPTION This transmitter is a transmitter device with tire valve, which is mounted in the valve hole of the wheel rim and transmits the pressure and temperature inside the tire, the battery voltage of the transmitter, and the tire identification code (ID) at normal and abnormal condition with the radio wave (RF) that conforms to the used area. Also this device has a countermeasure function such as the random delay of transmission time so that the RF signal from each tire will not interfere such as due to the simultaneous transmission. Description of Operations P/N Consumer’s Mfg. Mode of Explanation Frequency of Use Mode Modes Operation Transmission Storage Mode No transmission. Measures temperature. 4 words whenever LF 209624-125 X activation occurs 209624-126 Normal Mode No transmission. Measures temperature and 4 words whenever LF 209624-125 X Stationary pressure. Enters this mode from storage after activation occurs 209624-126 a valid LF activation occurs. Measures temperature and pressure. 4 words every 1 Normal Mode Transmits periodically. Enters this mode minute, 4 words LF 209624-125 X rolling from Normal Mode Stationary when activation occurs 209624-126 acceleration goes above threshold. Transmits when: 8 words every 4 209624-125 X Alert Mode a) significant pressure delta detected seconds for 1 minute 209624-126 b) high temperature is detected
