For NG, the address "00370000" and the readout data "dddd" are returned. (dddd: Production Process No) POWER OFF Correcting difference between the ambient temperature and the temperature read by the sensor. Comparing the ambient temperature and the temperature read by the sensor to transmit the corrected value. TMPADJ15: To raise temperature by 5 °C. TMPADJ25: To reduce temperature by 5 °C. * When the same commands are transmitted several times, corrected vales are not added. Provide the set in the IrDA jig mode to the other end of the line to perform the transmitting/receiving test. When IRDA is transmitted, the set in the IrDA jig mode receives signals and returns "5A". Detecting "5A", the tested set returns "OK" to the personal computer. When values are other than "5A", "NG aa" is returned. If data cannot be received, NG NODATA is returned. *3 When IRDACH5 is transmitted, using the command to set the IrDA jig mode, the jig mode starts. Reset, or disconnect the power from the set, to release the jig mode. *3 Checking vibrator operation. When VIB1 is transmitted, the vibrator operates continuously; when VIB2 is transmitted, it stops operation. Checking melody playback. *4 Checking read/write of 4Mbit SRAM. Checking read/write of 16 Mbit. Smartcombo RAM. POWER OFF when PWRDOWN is transmitted. [Note] In the test mode clock setting is reset; after finishing the test, if necessary, reset the current time by selecting [Date&Time] in [Settings] in the normal mode. 2 - 71
