@ REV switch Used to reverse the repeater shift (+600 kHz) to monitor a signal coming to a
REV repeater. Setting this switch to ON in simplex operation locks the displayed fre-
O quency regardless of VFO, keyboard, and COM*.CH operations. (* European
and British versions excluded.)
@ TX OFFSET switch Used to set transmit frequency (+600 kHz) shifted from the displayed receive
frequency when transmitting.
For operation other than that of a repeater, place this switch to the ‘’S’’ posi-
fou tion. This equalizes the transmit frequency with the receive frequency.
aa “4+ setting shifts +600 kHz; ‘‘—"’ setting shifts —600 kHz from the
receive frequency when transmitting.
This operation is only effective in VFO and MR (M1~M3) operations.
If a shift frequency goes beyond the operating frequency range when depress-
ing the PTT switch to transmit, a beep will sound three times to indicate the
misoperation.
However, transmit frequency is emitted in simplex mode.
*With the optional TU-3 tone unit installed, either ‘‘+‘' or ‘‘—"' setting of the
TX OFFSET switch interconnects the TU-3 2nd tone frequency setting.

The performance of the transceiver depends upon the type of antenna to be us-
ed. To ensure the maximum performance of the TM-201A, select a suitable
antenna and adjust it for low VSWR.

Notes:
© Before installing the power cable, be sure to remove the negative lead from the

e After installation and wiring, be sure to double check for correct installation
before reconnecting the negative lead to the battery terminal.
° If the fuse opens, be sure to check that each conductor has not been damaged by
short-circuiting, etc.
Then replace with a new fuse of the same rating.
° After completing the wiring, wrap the fuse holder with tape to protect against
moisture.
* Do not cut out the fuse even if the power cable is too long.
@ If the wiring hole in the fire wall or chassis is too small, disassemble the fuse
holder to thread the wire through the hole.
