Each jumper has three pins, labeled L, S, and M. A jumper plug is placed
over pins L and S, which is the default position for the pins. Moving the
jumper plug to place it over the following pin sets reconfigures the station
for the following line lengths:
• Long Lines. For line lengths in excess of 500 feet (152.5 m), place
the jumper plug over pins L and S. This is the default position to
which the unit is set when shipped from the factory.
• Medium Lines. For line lengths between 200 feet and 500 feet (61m
– 152.2 m), place the jumper plug over pins S and M.
• Short Lines. For line lengths less than 200 feet (61 m), remove the
jumper plug, or store it on the jumper by placing it sideways over pin
S.
2 JP-3 Interrupt Enable/Disable Jumper: Jumper JP-3 allows you to
select to either mute or not mute active talks when you use the stage
announce feature. The jumper has three pins. When shipped from the
factory a jumper plug covers pins 2 and 3 (ON). When the jumper plug is
placed over pins 2 and 3, active talks are muted when you use the stage
announce feature.
Placing the jumper plug over pins 1 and 2 turns off the muting feature, so
that active talks can be heard even when the stage announce feature is
used.
3 Headset Audio Limiter: To protect the hearing of the user, the headset
audio limiter restricts the maximum audio level heard in the headset. By
default, this feature is on when the station is shipped from the factory. You
can turn this feature on or off using an internal three-pin jumper.
To turn the headset audio limiter on or off:
1. Ground yourself and tools before opening the station or performing
any operation on the circuit board. Circuitry can be damaged by static
electricity.
2. Unscrew the top and side screws on the station’s cover, then lift the
cover off the station.
3. Locate the three-pin jumper labeled “JP4” on the circuit board.
A jumper plug connects pins 2 and 3 of the jumper. This is the on
position for the headset audio limiter feature.
4. Lift the jumper plug off pins 2 and 3 and place it over pins 1 and 2.
This is the off position for the headset audio limiter.
The headset audio limiter feature does not operate when the jumper
plug is in this position.
5. To turn the headset audio limiter feature on again, lift the jumper
plugs off pins 1 and 2 and place them over pins 2 and 3.
The headset audio limiter feature operates when the jumper plug is in
this position.
