HEADPHONE JACK REPLACEMENT:
Because it is subject to heavy use, it is normal for the contacts in the headphone jack assembly to wear out over
time. The 2.4Ghz receiver is equipped with a replaceable headphone jack module to address this wear without
replacing the entire unit. Under ideal conditions, the headphone jack is rated to last roughly 6,000 plug insertions
and removals (cycles). After 6,000 cycles, an icon that looks like headphones will flash in the display to alert that
the headphone jack should be replaced. Every time the receiver is powered-up, the display will flash the number
cycles the module has used under the letters “2.4G”. The headphone jack module can, in most cases, be
changed without removing the receiver unit from the cardio machine.
