KX-MB772CX-V1 CROSS REFERENCE: Test Functions (P.89) 151 KX-MB772CX-V1 CROSS REFERENCE: Test Functions (P.89) 152 KX-MB772CX-V1 CROSS REFERENCE: Test Functions (P.89) 153 KX-MB772CX-V1 154 KX-MB772CX-V1 155 KX-MB772CX-V1 CROSS REFERENCE: Test Functions (P.89) 156 KX-MB772CX-V1 12.3.13. Initializing Error After the power is turned on, the SOC (IC300) initializes and checks each IC. The ROM (IC402) and SDRAM (IC400) are checked. If initialization fails for the ICs, the system will not boot up. In this case, please find the cause as follows. CROSS REFERENCE: NG Example (P.238) Power Supply Board Section (P.69) 157 KX-MB772CX-V1 12.3.14. Analog Section and Monitor Section This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on each route is shown in the Check Sheet here. If you find a specific problem in the unit, for example if you cannot communicate with the H/S, trace that signal route locally with the following Check Sheet and locate the faulty point. 12.3.14.1. Check Sheet 158 KX-MB772CX-V1 12.3.14.2. DEFECTIVE ITS (Integrated Telephone System) Section 1. No handset and speakerphone transmission / reception Perform a signal test in the ITS or the NCU section and locate a defective point (where the signal disappears) on each route between the handset microphone and telephone line (sending), or between the telephone line and the handset speaker (receiving), or between the microphone and the telephone line (sending), or between the telephone line and the speaker (receiving). Check the components at that point. Check Sheet(P.158) is useful for this investigation. 2. No pulse dialing 3. No ring tone (or No bell) CROSS REFERENCE: Check Sheet (P.158) NCU Section (P.29) 4. No tone dialing CROSS REFERENCE: Check Sheet (P.158) 159 KX-MB772CX-V1 12.3.14.3. Detective TAM Interface Section 1. The FAX turns on, but does not arrive through TAM. CROSS REFERENCE: TAM Interface Section (P.31) 2. A FAX is received, but won't switch from TAM to FAX. CROSS REFERENCE: Analog Section and Monitor Section (P.158) TAM Interface Section (P.31) 160 KX-MB772CX-V1 12.3.15. Operation Panel Section Refer to Test Functions (P.89). 1. NO KEY OPERATION 2. NO LCD INDICATION CROSS REFERENCE: Test Functions (P.89) 12.3.16. Sensor Section Refer to SENSORS AND SWITCHES for the circuit description. Perform an SENSOR CHECK to determine if the sensor is operating correctly. 1. Check the pickup sensor ... "FAILED PICKUP" 161 KX-MB772CX-V1 2. Check the paper exit sensor... "PAPER JAMMED" 3. Check the read position sensor ... "CHECK DOCUMENT" 4. Check the registration & manual paper sensor ... "PAPER JAMMED"
