| Accessories | none |
| Condition | Front excellent. Back cover pretty dirty. Only a few dots on the display come on when the power supply is connected |
| Repairs, Comments | 14.11.2002 Tried to repair the unit. Removed the
plastic back cover and then 4 screws underneath the paper. The metal
shield then easily comes off. Unsoldered the connector wires to the
batteries. Couldn't find anything by visual inspection. However, I noticed that there must be a contact problem somewhere: At one point I had the display working and could even execute a calculation. So in principle it is working! Note that a dot on right side of the display seems to indicate when the power supply is connected. It is lit regardless of the setting of the power switch. 29.1.2003 Fixed a contact problem at the power connector. But I was unable to repair the 0/1 switch. In the end I had to solder a wire so that the calculator is permanently on regardless of the 0/1 switch when the power supply is connected. Note that the unit won't work with batteries any more. |
