Good quality. Quick service. I recommend to everyone.
;
Very good quality scan of the document. I am very pleased with what I got.
;
PDF Contains
Technical Data, Mechanical data, Detailed Circuit diagram with components value, PCB layout. Actual PCBs Print. Component List, Spare parts code list and Input output detail. It cover LBB1211, LBB1212, LBB1213, LBB1216, LBB1217.
It is the actual Service Manual for SQ10
;
very good manual with clear electrical schemes. Very helpful to find wat was wrong inside my microwave.

Hi, thankyou for providing the Nordmende Globetrotter original manufacturer's repair manual. Quality is very good and sharp - the PDF file was comfortably small to download. The only question is: why did it take so long to become ready for download?? Many thanks anyway, I fixed the fault in the radio thanks to the circuit.
regards: Nick

HANDSET
� Make the set in the test mode. (See page 16) 1. Power Failure Test Procedure: 1. In the test mode idling status, press the [1] key to display �TEST A�. 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 �
4. Current Measurement Setting:
Handset regulated dc power supply + +3.8 V TP102 (GND) �
A
TP101
Procedure: 1. Connect equipments as the figure above. 2. In the test mode idling status, press the [1] key to display �TEST A�, and press the [5] key. 3. Check that the value of ammeter is 100 to 400 µA.
Note: The set cannot start up if resistance of ammeter is too much.
5.
Between Microphone and Speaker (CODEC Loop
Back) Signal Level Measurement Setting:
audio analyzer 1.2 kHz, �35 dBm LPF: 30 kHz ON Output GND Input
Procedure: 1. Connect equipments as the figure above. 2. In the �TEST A� 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 + � regulated dc power supply + +5 V (power off) � 10 � charge terminal + charge terminal � + � Handset TP32 TP102 (GND)
10 µF +
Handset TP6 TP5 (MIC GND) TP3
150 � GND Base unit RF271 RXAD TXAD short (remove the R446, 447) RF61 TP4 (GND)
Procedure: (Use the panel for normal set) 1. Connect equipments as the figure above. 2. Remove the R276, R277, R446 and R447 on the BASE MAIN board. Then connect between RF271 pin qs (RXAD) and RF271 pin qa (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 [4] key of the handset to display �TEST D�. In the test mode idling status with the base unit, press the [4] key of the base unit to display �TEST D�. Set the output level of audio analyzer to �35 dBm (1.2 kHz, LPF=30 kHz ON). Check that the value of audio analyzer is �12 to �18 dBm.
digital voltmeter 2
Procedure: 1. Connect equipments as the figure above. 2. In the �TEST A� 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 �L� to �H�. 4. Check that the value of digital voltmeter 2 (voltage of 10 � 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 � resistor) is 1.2 to 1.4 V. 7. Disconnect the regulated dc power supply.
3. 4. 5. 6. 7. 6.
Between Microphone and Speaker (CODEC Loop Back) Signal Level Measurement (H to H Gain Up) Setting: Same as step 5. Procedure: 1. In the step 5 �Between Microphone and Speaker (CODEC Loop Back) Signal Level Measurement� status, press the [*] key of the handset. 2. Change the output level of audio analyzer to �35 dBm. 3. Check that the value of audio analyzer is �6 to �12 dBm.
