The Owner's manual was very helpful. The WEGA is about 35 years old and needed repair.
Your Website is pretty good und easily to handle.
Thank You

This manual is very helpfull to use the Power Supply. All technical information has been available.
For service use the circuit diagrams are very good.
Thanks .

Very comprehensive document which is a must-have for any Satellit 2100 owner whose set up is somewhat intricate. Due to the bad quality of the pictures that are rather dark and a bit blurred I gave 4-star feedback.

HANDSET
� Make the set in the test mode. (See page 15) 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)

Handset TP6 TP5 (MIC GND) TP3
150 � 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 [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.
