only access to the engine ECM module. In the “Engine Interface” mode, the engine ECM will
perform a self-test and then enter its Run mode. (The display will indicate running in the engine

18) Confirm Battery Replaced
Situated on the back of the control board, is a coin type lithium battery which ensures that Firmware /
Set-up data etc. are not lost during utility drop-outs. The expected life of the battery is approximately 7
years. Note, a low battery voltage does not affect the internal safety system of the GPU that monitors
the output voltage, among others. Thus, aircraft connected to the GPU are not exposed to any danger.
However, to avoid loss of data and Control Board lock up *, we recommend changing the battery after
5
years
of use.
Note!
A time stamp is stored in the ID chip (A6) upon production and after 5 years a warning occurs at the
display, telling the user/operator to replace the Control Board battery. It is strongly recommended to
change the battery when this message is shown:
