3.8 FAN TEST
The fan is controlled by the transceiver unit and operating only when the
station is keyed.
If the fan does not start when the station is keyed, check that the transceiver
unit supplies 12V on P7:1 on the interconnection board. If 12V is present,
replace the fan. If the transceiver does not provide 12V on P7:1 it is faulty.
