Factory Reset Using Push-Buttons#

Added in version r7.16.

In extreme cases where a misconfiguration causes the clock to enter a reset loop, the clock menu becomes inaccessible, and it is impossible to invoke the default values through the menu.

The issue can be resolved by using a specific combination of push-button presses to perform a factory reset.

Procedure#

Connect the clock to power supply.
Press and hold PB1 and PB2 push-buttons at the same time.
Restart the clock by briefly pressing the reset button while holding PB1 and PB2 push-buttons at the same time.

Hint

The reset button is located inside of the clock on clock’s control module located on PCB.

First, you need to dismount the front cover and plexiglass (see Single sided chapter) and you also need to dismount the clock PCB.

The button is small yellow button labeled RESET.
Hold both PB1 and PB2 push-buttons until FAC appears on the clock display (in approx. 5 seconds).
Release PB1 and PB2 push-buttons. The clock restarts to factory settings.
