Straight answers
Spectra 010897-99S — Straight Answers.
Which receivers do the Spectra 010897-99S knobs fit?
The LR30, LR30W, LR50, LR50W, LR60 and LR60W.
Do I get the clamps too?
No. The pack is two knobs only. The clamps are Spectra 010459-99S, sold separately.
How do the knobs work?
Turn the top and bottom knobs counterclockwise until the clamps open enough to fit round the mast, place the receiver, then turn clockwise to tighten. To remove the receiver, loosen the two clamps.
Are these the same as the battery door screws?
No. The knobs hold the receiver on the mast. The battery access cover uses a different pair of thumb screws, Spectra 002102-99S.
