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 900MHz 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 “UHF”. The headphone jack module can,
in most cases, be changed without removing the receiver unit from the cardio machine.
1. To remove the worn jack, locate the two Philips screws on the front bottom of the unit. They will be covered
by a felt insert on either side of the headphone/power logo.
2. Remove these two screws and set the screws to the side.
3. The headphone module will drop out of the unit.
4. Replace the headphone module and insert and tighten the two screws.
5. Plug in a set of headphones to power on the receiver
6.
Press the “SET” and “MEMO” buttons for about six seconds to enter into the programming mode
7.
Press the “DELETE” and “MUTE” buttons for eight seconds till the flashing headphone icon disappears.
8.
Press the “SET” and “MEMO” buttons for about six seconds to exit the programming mode.
