Turn the radio off. Disconnect
the power source. Open the
bottom cover by removing the 4
screws located on each corner of
the bottom cover surface. Locate
a BLUE looped jumper wire that
comes out of a slot on the back
of the front control unit (it is
attached to the back of the
front panel on a pad). Remove
the jumper and trim the
remaining wire properly to
prevent a short circuit.
Reassemble the bottom cover.
Connect the power source and
turn on the unit with the FUNC
key pressed to reset the
microprocessor. Settings will
become the factory default.
The unit will transmit and
receive between approximately
200.000 and 299.999 MHz where
the VCO will lock. If the
display is flashing, you have
lost VCO lock and operation is
not possible.
Also, if you press the FUNC key
and the SQL key when you turn
the power on you will get a
handy digital voltage display.
