2.6.3 Volume
The volume of the music on hold can be adjusted in two ways. First, the playback volume of the
music source can be adjusted, or the Music Vol. control (Item 3 Page 7) of the 2743 may be
adjusted. Adjustment of the Music Vol. control requires a small screwdriver. Turn the control
clockwise to increase the volume or counterclockwise to decrease. It is preferable to adjust the
volume at the music source.
2.6.4 Requirement
The 2743 requires a system of at least two 4-line telephones. Music will not be provided to a
single telephone system
2.6.5 Copyright
Please remember that it may be necessary to obtain a license when using equipment that
rebroadcasts copyrighted material.
2.6.6 Troubleshooting
If callers are not receiving music on hold, please check the following items.
1. Remember that a system of at least two 4-line telephones is required for music.
2. Verify that the AC adapter is plugged into a working outlet. The outlet may be
verified by plugging a lamp or other device into it.
3. Verify that the AC adapter is plugged securely into the 2743. This may be verified by
checking that the 2743 status indicator is blinking.
4. Check the volume. The volume may simply be too low for music to be heard. See
Section 2.6.3 for volume adjustment.
5. Test the music source. Unplug the cable from the music input jack on the back of the
2743. Then place a call and place the caller on hold. The caller should now hear
music from the music IC of the 2743. If the caller hears music now, there is a problem
with the music source.
6. Test the telephone wiring. Plug a standard telephone into the jack where the 2743 is
connected. Verify that you can make and receive a call. If not, the wiring is defective.
