The Shure Wireless Systems: T Series User's Guide provides a de-
scription, information on operation and troubleshooting, and technical
data.
The Wireless Service Equipment manual covers the standard items
needed for servicing the transmitters. If you do not have the modified
4 receiver described there, you will need an appropriate receiver (usu-
SC
ally T3 or T4) to verify that the transmitter is working properly.
Each transmitter circuit board is marked with a group letter (A, B, C,
or T) that identifies the range of frequencies on which the transmitter can
operate. Table 1 shows the Group Letter and its associated frequencies.
Note that this chart applies only to the T1 series.

Table 2 provides information for identifying the system frequency.
The Crystal Letter Code, when used with the appropriate Shure model
number, identifies a specific operating frequency for both transmitters
and receivers. Note that, although a Crystal Letter Code always desig-
nates a specific frequency, it may be used with different Group Letters on
other products.
Group T: Beginning in July 1995, "V" and "W" frequencies, formerly
assigned to the "A" board, were reassigned to a newly designated "T"
board (see the "Audio Alignment" subsection in "Service Procedures").
