While you may get a green power light indication (SBY), there may not be sufficient battery power to run the
motor. We suggest for long term operation use the optional Universal Power Supply 9VDC available from
preciseRF.
INSTALLING THE HG-1 MOTOR DRIVE ASSEMBLY.
1.
Open the existing HG-1 manual tuner case. (Refer to the
figure). Take care not to damage the tuning capacitor by
setting the frequency to its lowest setting.
2.
Remove the existing knob and pointer (save them for
potential future use).
3.
Remove the existing mounting screws securing the 6:1
reduction drive (save any spacers or nuts).
4.
Remove the temporary nuts securing the two spacers
attached to the HG-1 motor assembly.
5.
Attach the HG-1 motor assembly to the capacitor shaft.
6.
Using the supplied longer #4-40 screws, mount the HG-1
motor assembly to the 6:1 reduction drive.
7.
Tighten the set-screws and reinstall the HG-1 manual tuner
case back.
ADJUST THE TORQUES SENSOR AND REPLACING THE BATTERY (applies
the HG-1 REMOTE TUNER retrofit only)
The red LED limit indicator illuminates when the capacitor has
reached the CW and CCW position. Because there is some
variation in 6:1 reduction drive torque, the sensor can be
calibrated.
1.
Refer to the figure. Open the back of the remote controller case by removing the four screws. Note
the blue miniature potentiometer located on the interface board.
2.
Set the RATE to MAX. While pressing the UP and Down buttons adjust the blue potentiometer such
that the red LED limit indicator illuminates brightly when the capacitor reaches the CW and CCW
ends. It is normal for the red LED limit indicator to flicker occasionally. (You may have to repeat this
adjustment as the 6:1 reduction drive loosens over time).
3.
The battery may also be replaced at this time. Battery life depend on type and use. Generally, it
should last for an extended tuning session. Turn the remote off when not in use.
4.
Replace the back cover of the remote controller being careful not to pinch any of the wires.
