This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.
Mi spiace per non poter scrivere in inglese... ma sono veramente soddisfatto del servizio offerto. Grazie..!!
The quality of this manual is good. It has all schematics and setup information for both the MDS-B3 and the MDS-B4. The scan quality is quite good, all pages are readable, This service manual also contains scans of the operating instructions from the User manual.
Quick site processing. A complete and very useful manual with all details. Thank you!
Das Service Manual war von der ersten bis zur letzten Seite sehr informativ und hilfreich. Die Darstellung aller Teile war klar und der Text gut lesbar.
Vielen Dank, das war nicht der letzte Download bei ownner-manuals.com.
â¢ Make the set in the test mode. (See page 15) 1. Power Failure Test Procedure: 1. In the test mode idling status, press the  key to display âTEST Aâ. 2. Check that the key back light on the handset lights up when connect between TP105 and TP104 (GND) on the HAND MAIN board. 2. Low Battery Test Setting:
Handset TP101 TP102 (GND) regulated dc power supply + +3.8 V â
4. Current Measurement Setting:
Handset regulated dc power supply + +3.8 V TP102 (GND) â
Procedure: 1. Connect equipments as the figure above. 2. In the test mode idling status, press the  key to display âTEST Aâ, and press the  key. 3. Check that the value of ammeter is 100 to 400 ÂµA.
Note: The set cannot start up if resistance of ammeter is too much.
Between Microphone and Speaker (CODEC Loop
Back) Signal Level Measurement Setting:
audio analyzer 1.2 kHz, â35 dBm LPF: 30 kHz ON Output GND Input
Procedure: 1. Connect equipments as the figure above. 2. In the âTEST Aâ status, check that the LCD back light on the handset lights up when change the voltage of regulated dc power supply to 3.2 V. 3. Charge Detection and Current Control Test Setting:
digital voltmeter 1 + â regulated dc power supply + +5 V (power off) â 10 â¦ charge terminal + charge terminal â + â Handset TP32 TP102 (GND)
10 ÂµF +
Handset TP6 TP5 (MIC GND) TP3
150 â¦ GND Base unit RF271 RXAD TXAD short (remove the R284, 285, R287 and R288) RF61 TP4 (GND)
Procedure: 1. Connect equipments as the figure above. 2. Remove the R284, R285, R287 and R288 on the BASE MAIN board. Then connect between RF271 pin qd (RXAD) and RF271 pin qs (TXAD) on the BASE MAIN board by lead wire. Set the [VOL] switch on the handset to [H] position. In the test mode idling status with the handset, press the  key of the handset to display âTEST Dâ. In the test mode idling status with the base unit, press the  key of the base unit to display âTEST Dâ. Set the output level of audio analyzer to â35 dBm (1.2 kHz, LPF=30 kHz ON). Check that the value of audio analyzer is â12 to â18 dBm.
digital voltmeter 2
Procedure: 1. Connect equipments as the figure above. 2. In the âTEST Aâ status, turn the power on of the regulated dc power supply (+5 V) to start charging. 3. Check that the level of digital voltmeter 1 (voltage of TP32) changes from âLâ to âHâ. 4. Check that the value of digital voltmeter 2 (voltage of 10 â¦ resistor) is 110 to 150 mV. 5. Press the [*] key to start quick charge. 6. Check that the value of digital voltmeter 2 (voltage of 10 â¦ resistor) is 1.2 to 1.4 V. 7. Disconnect the regulated dc power supply.
