1. Viewing the alarm memory
The Alarm Memory function allows you to know all events that occurred in the LAP, such as forced cooling activation, alarms, and shutdowns. This memory is non-volatile and cumulative, meaning it allows you to know all events that occurred, but not when they occurred.
The Alarm Memory is accessed by simultaneously pressing the 
and 
buttons. The alarm sets ALM1 and ALM2 will be displayed on the screen and will alternate with the alarm code. It is possible to navigate between these sets using the 
and 
buttons.
To reset the Alarm Memory, press the 
button for 5 seconds. If there is any active alarm, the memory will be reset, already indicating its occurrence. Press the 
button to return to the indication screen.
The alarms are indicated in hexadecimal format, but as there are more error codes than would be possible to indicate with only 4 digits, it is necessary to use two sets (ALM1 and ALM2) to indicate them. In the case of two different events, the result displayed in the position relative to this event is a sum of them. Below is the table with possible error combinations for each digit.
Code | Description |
0 | No active alarms |
1 | Alarm 1 active |
2 | Alarm 2 active |
3 | Alarms 1 and 2 active |
4 | Alarm 4 active |
5 | Alarms 1 and 4 active |
6 | Alarms 2 and 4 active |
7 | Alarms 1, 2 and 4 active |
8 | Alarm 8 active |
9 | Alarms 1 and 8 active |
A | Alarms 2 and 8 active |
B | Alarms 1, 2 and 8 active |
C | Alarms 4 and 8 active |
D | Alarms 1, 4 and 8 active |
E | Alarms 2, 4 and 8 active |
F | Alarms 1, 2, 4, and 8 active |
