This classification shall be adjusted by each distributor because it depends on model number, temperature, humidity, etc.
e When ordering resistors, first convert resistance values into code form as shown in the following examples.

9.FOR Z TYPE
9.1 DIFFERENCES BETWEEN THE Z/UC TYPE AND Z TYPE
_ Exactly the same parts are used to configure the Z type
and Z/UC type. The difference between the Z type and
Z/UC type is that the FM/AM CHANNEL STEP
switch (S500) is set to 100/10 kHz for the Z/UC type and to
50/9kHz for the Z type at the factory. Set the Z type to the
channel step for the area where used, as shown in the sche-
matic diagram below. (The Z/UC type should be left at 100/
10kHz.)

9.2 PACKING OF OPERATING INSTRUCTIONS
In some cases, the TX-1080Z/Z type is sold together
with the Model SA-1480/SD type, SD/G type, SA-1280/
