In the default Pre-Set mode the Low Frequency button will deliver a frequency of 2Hz and the
High frequency button will deliver a frequency of 60 Hz.
When and How to use Low:
Low frequency will create relaxing rhythmic muscle contractions. Though they can get very strong
they should remain comfortable and are completely non-fatiguing; this makes them ideal for moving
nourishment and waste the keys to conditioning and recovery (but remember Marc Pro Plus’s unique
low frequency technology can also really help soreness as well).
It’s hard to go wrong with Low Frequency as it can benet all major muscle groups, but use common
sense. No need to try to pump low frequency through a knee or ankle joint; there’s just not much
muscle to contract. Instead contract the largest muscles around your target to bring nourishment in
and get waste out. The stronger the contractions the better as long as it remains comfortable and
within your tolerance.
A 30-60 minute session is great, but there’s not much of a time limit on low frequency as it won’t
fatigue your muscles and just keeps helping more the more you use it.
Low and High Frequency Together
As you’ll see in the following examples it is common to combine settings. For example Channel A will
use low frequency on the quad to recover (moving nourishment and waste) while at the same time
Channel B is sandwhiching the knee shutting down any residual extremity pain.
