Figure 6–9: AM700 startup menu
The second method of accessing the Low Level diagnostics menu starts with the
power off. This method is referred to as the “backdoor boot modes.” Press and
hold the Menu button while turning on the power. After the AM700 beeps twice
to acknowledge the startup mode, release the Menu button. The AM700 then
initializes directly into the Low Level diagnostics mode as shown in Figure 6–9.
