Hold down the F and MHZ keys while turning on power.  The current
control band will display CLonE.  Pressing CALL initiates the data
transfer, graphically illustrated by a moving S-METER display.  No
RF is transmitted during data transfer, instead it is assumed that
the data is dumped out of the microphone port.  Nothing more is
known about this at this time.

AM DETECTOR CONTROL

The AM Detctor, which automatically comes on below 136 MHz, can be
forced ON at any VHF frequency by pressing the F and MUTE keys
while applying power.  Radio continues to transmit FM but receives
AM.  Changing frequencies or memory channels will cancel the forced
AM mode.  This capability could be useful for listening to the
USAF Thunderbirds which sometimes operate in the 143 MHZ band using AM.
