Turn off the radio, hold the reset button in WHILE turning on the radio.
Also, isn't the reset button on the opposite side of the radio from the
ptt switch?, and the function switch is alongside the ptt???? It should
be the same setup as the C228A (2M/220)..... Also, you might need to
have the memory cart reinitialized. I hope not though.

Good luck!

I have a Standard C528A twin-band (2m/440) HT that's 12 years old.
I've not

week, I
powered it up using an external supply and it simply acted bonkers. It
would not respond properly to all keypad commands.

Taking the HT apart, I found a dead 3-volt lithium battery. I
replaced it
with a fresh one, hit the little reset button inside the push-to-talk
switch, but to my chagrin found absolutely no change. The radio still
acts
like it's stuck in a particular mode and I cannot punch in a frequency
with
the keyboard.

Am I not resetting this radio properly? Is there a particular
sequence of
keys I need to hit?

Thanks!!!!

Try turning the radio off.
Hold down the "F" key, the "Mon" key and turn on the power. You may
hear a series of beeps then release the keys.

I have a C510 and this is how the reset sequence goes for it and they
may be using the same CPU or programming for it.
