Operating Instructions Introduction A view of the transceiver FSG 5W is given on the last page of this Manual. Please fold out the back flap when reading the operating instructions. Each number of a control, switch, etc. corresponds to the number of the control, switch, etc. given below.
• Verify that the display (6) shows your desired operating frequency. • Hold the transceiver FSG 5W in the left hand, with the microphone area (10) as close as possible to the upper lip. This technique is necessary because the noise cancelling feature of the micro- phone favors sound close to the microphone and discriminates against sounds away from the microphone.
• An external power supply (12 VDC from car or aircraft supply, negative ground) or a battery charger may also connected via socket (1). Even the 12 VDC supply of external accessories like our VOX 90 is possible (then the FSG 5W must be switched ON) •...
Hold antenna neither close to your skin, eyes, other electronic equipment, nor touch it! Functional Checks When the transceiver FSG 5W does not operate correctly, check the following: • Is desired operational frequency adjusted? • Carry out a battery test without any charger or external supply connected.
