Yaesu VR-500 - Stopping The Low Battery Beep And Resume Scanning

[WartHog]

There is a way to stop the low battery beep without removing the batteries, and
totally shut down the radio. You will even be able to turn the radio back on
again after waiting a bit, and resume normal scanner operations for a very short
while, a minute or two or three.

Press the same buttons you would use as when interfacing with another radio or
computer. While holding down the numbers 1, 8, and the enter key all at the same
time, then depress the power button. Now the display changes to the cloning
screen, and at the same time all radio back lighting is turned off, and you will
see the low battery indicator present on the display. (The low battery indicator
to my knowledge only has one bar, simply an icon that presents itself). Keep
the radio in this mode for at least two minutes minimum. By the way, in this
mode, I do not know what the energy draw is, but it is very low. I've never
noticed how long it will last in this mode, but it's well over half an hour in
this state). But the point is to turn the radio off, so now, after waiting the
required minimum two minutes, depress and hold the Function key and the CLR key
and the radio will resume normal operation. As soon as this happens, depress the
Power key and turn the radio off.

Many times, exhausted batteries have a way of re-energizing themselves somewhat
when there is no load on them for a while.
(I won't attempt to explain this, as I am not an electronics engineer). So if
you leave your scanner off for say five minutes, you will be able to turn it on
again and resume normal functions for a short while. (Interesting, that when you
are finally back in this mode, if you were using the lamp lighting, it is back
on again now too.) And here's the kicker >> you can repeat this cycle over
again, and again, and again. You won't be able to sustain normal scanner
operations very long, (it will get shorter each time), but you will be able to
scan that band again a few times, or make a few sweeps of your search, to hear
that important traffic you're missing.
