H. Minimum Signal Adjustment

1. Minimum Signal Adjustment (suggested increment : 20; valid range: 2-200)

Change this figure to admit minimum signal amplitude, in another word

any signal smaller than the level here will be ignored.

Decreasing the number will increase the sensitivity of system but also at

the risk of false alarming.

Vise versa, increasing it will lower down the sensitivity to overcome the

unexpected false alarming caused by uncontrollable environment noise.

2. Configuration Loading Mode Setting (range: 0-1)

Also under this setting entry, there are three modes of system

configuration loading.

Inputting 1 will set the system to power on self-detection mode in which

system will automatically configure all the parameters.

By inputting 0, system will load the default parameters from Flash ROM. (See

the default parameters table)

If this parameter is bigger than 2(use as Minimum Signal Adjustment), system

will load the latest saved parameters.

Note: Default parameters are NOT equivalent to the latest saved parameters.
