Battery Save Test: What does this do?

[JHaislet]

Powering on holding (1+5+8) scanner turns off. Then when you power on again, it pulls up a screen called:
BATT. SAVE TEST
ON (RF_PWR = L)

or, if you hit "HOLD" it changes to:
BATT. SAVE TEST
OFF (RF_PWR = H)
(and you hear two levels of background static).

What exactly is this doing? Mine defaults to "OFF (RF_PWR = H)" when I first run this test, even though I have Battery Save turned on for the scanner.

1+4+8
1+5+8
2+4+7
2+4+8
2+5+7

Those keys, I believe, are all part of undocumented Uniden BCD396T test modes for fault-finding purposes by factory and service technicians. (Undocumented by Uniden, but mostly documented by me though!!! hehehe...)

There are many more of those (2 pages) right here:

This is a functinoal test mode which verifies that various portions of the receiver are properly shut down during battery save operation. This is why you hear distinct differences in bacground noise. You should also measure differences in supply current.
