FSG 7016
4 Operation
28 D10011 November 2009
4.10 Siting
• The radio operates in the UHF frequency band, this is a Line-Of-Sight (LOS)
frequency; therefore, siting of the radio greatly affects its operating range.
• The longest range is normally obtained when a direct LOS is maintained
between the radios.
• Use of hilltop or tower locations will increase the LOS range.
• Hold/place antenna above operator's head/helmet for best omnidirectional
radiation.
• Location in valleys with intervening hills, behind vehicles or buildings or in dense
woods may reduce or prevent communications.
• If possible, avoid locations near electrical interference sources, such as
computers, power and telephone lines, radar, welders and electrical generators.
4.11 Functional Checks
If the transceiver FSG 7016 does not operate correctly, check the following:
• Is the required channel adjusted with the 'CHAN' knob? Adjust required channel!
• Is battery supply sufficient? Press and hold side TEST key, observe 'TX BATT'
LED or listen to battery status tone, particularly during transmit. At least a two-
dot sequence should be visible and audible!
• Weak RX signal? Press side TEST button = switch OFF squelch circuit!
• Weak TX signal? Check external microphone, position of EXT MIC SENS knob,
radio, or antenna system! Is the voice volume too low? Speak loud and clear
while the lips are facing the microphone! Try another location! Make sure that
transceiver's antenna is vertically positioned and is not screened by nearby
placed metallic objects or buildings.
• Singing during transmit? Adjust EXT MIC SENS less sensitive (turn 1 step ccw);
keep external microphone in other position!
• Rattles when receiving? Metal propellers between transmitting airborne radio
and base station antenna!
• Called station hears carrier, but no voice? Check external microphone and
contacts on microphone jack! Monitor transmit sidetone!
• Noisy - distorted - garbled? Suppress interference of motor aircraft or vehicle
(generator, regulator), check antenna system; check antenna-, microphone- and
radio- connector for proper seat! Change location!
• Transmitter switches off itself? Transmitter was keyed longer than 5 minutes.
Release PTT key, normal operating is possible again; or the battery is flat!
• In case of doubt, compare operation of the transceiver with another transceiver
on the same location or call another station. If service is necessary please
consult your authorised dealer or an approved avionics workshop.
