Instruction Manual
Frequency Counter
In order to operate the Frequency Counter (#4 Fig. 1), the unit must be
plugged in. Once the unit has power, the Frequency Counter will operate
automatically, whenever the microphone is keyed.
General Notation
On Grounded Grid amplifiers, we do not recommend checking modulation
at higher powers. Grounded Grid amplifiers will not be able to output 100%
modulation in the A.M. mode, however, the feed through power prevents
the grounded grid from being fully modulated. This is the reason A.M.
modulation should be checked at the transmitter, or with the Linear
Amplifier in standby position.
Light Operation
On the rear of the TFC-3001 unit, there is a power plug-in adapter.
Insert the jack of the supplied power pack, and plug pack into wall outlet.
To operate the Lights on the unit, use the switch located on the rear of the
unit.
