External switch connection
External switches can be connected to the TB1 terminal in the processor unit to pro-
vide one-touch access to a desired menu item or menu. Up to four external switches,
each with an individual function, can be connected.
Use a push button switch (momentary contact) for the external switch. For how to as-
sign the function to the external switch, see the operator's manual.

External KP connection
Note: To use the 3D functions, output the KP signal from the transceiver unit to exter-
nal equipment. If the KP (Keying Pulse) signal is synchronized from external equip-
ment, the 3D function may not work properly.
KP input
To synchronize the KP (Keying Pulse) signal from external equipment, make the con-
nection as follows:
• When the external equipment is a current drive circuit: Use the TB8-1 and TB8-2.
• When the external equipment is a voltage drive circuit: Use the TB8-3 and TB8-4.
The signals for current and voltage drive circuit cannot be used simultaneously.
