Socket 14 , before checking the battery supply.
 Press the red test button of the battery indicator 11 .
 The LED indicators 11 will light up.
5 LEDs ON = battery fully charged, supply OK!
3 to 4 LEDs ON = battery partially discharged; reduced
operation time when powered only from
the battery.
2 or less LEDs ON = battery discharged. The battery should
be recharged or the radio should be
powered by an external 12 Vdc source
of adequate capacity (e.g. automobile
battery).
Additionally the transceiver FSG 2T includes a 3 digit display of the
actual supply voltage level while in the DIRECT TUNE MODE. At dc
levels below 11 V the voltage digit value starts automatically flashing
for low supply warning!
