The clock won't start at all
Remember that it takes a few seconds after inserting the batteries before the clock will show its display.
Exhausted batteries,
The most likely cause of not starting is that the batteries do not give enough voltage. If you have the proper
equipment then measure the voltage of each battery, It should be more than 1.4 Volts.
When you leave exhausted batteries for too long in the clock, there is a possibility that the acid in the
batteries have destroyed the contact, or perhaps the whole clock.
The battery holder is a standard item that can be bought in each electronics store, as well as the "push
button" connector that connects this unit to the circuit board.
To check if the connections on the board are all right, you can measure the voltage over the capacitor
indicated in the picture. The voltage should be 0.6 Volts below the battery voltage, so 5.4 volts or higher with
fully charged batteries.
The clock can be reset by connecting the two terminals for the power.
Be sure to disconnect the batteries first.
This may revive the clock at some occasions.
If you can not find any missing contact here, then read the advanced repair manual for the DGT 2000. The
chance of reviving such a clock are slim though.
The lever switch does not click any more.
After long use the click mechanism of the lever may be worn out.
You can try to adjust the center screw first. Tighten it when the switch does not click enough or jumps back
sometimes or loosen it when the lever is moving with too much resistance
