PSR-300 Light

[FCVPI99]

ok i know not the same radio
my old Pro 97 i was able to make the light stay on till i turned it off
can you do the same thing with PSR-300??? so far i have been able to get it to stay on for like 20 sec only

Press and hold the light button for about 5 seconds and it should stay on. I had one for years but sold it when I got a PSR-500 which also operates the same way

I highly recommend bookmarking the "easier to read" manuals for all of your scanners

In any backlight mode, you can press and hold the light/key lock key for about 1 second to force the backlight on full time. Press the key while the backlight is on to turn it off.

To turn on the Keylock, press FUNC then light/keylock key.
