RE-SETTING PROGRAM INTERRUPT
OPTIONS
When you set one of the front-panel Program ON-OFF-INTRPT switches to
the INTRPT position, any talk signal activated on that channel interrupts the
program audio during the talk signal.
You can change this option so that activating a call signal, rather than a talk
signal, interrupts the program audio for the duration of the signal. You do this
by re-setting an internal jumper on the station’s internal circuit board.
To re-set the program interrupt option:
1. Please observe anti-static procedures. Static electricity can damage a
circuit card. Please ground yourself and tools before touching the circuit
card.
2. Remove the cover of the MS-702 by removing the eight Phillips screws.
3. On the main circuit board, locate one of the following:
• For channel A: The JP5 three-pin jumper, located in the center of the
circuit board.
• For channel B: The JP6 three-pin jumper, located in the center of the
circuit board.
4. A jumper plug covers two of the three pins on each jumper. To change the
program-interrupt option on your station, do one of the following:
•
For channel A: Move the jumper plug so that it covers pins 2 and 3.
This causes call signal activation to interrupt the program audio
• For channel B: Move the jumper plug so that it covers pins 2 and 3.
This causes call signal activation to interrupt the program audio.
