When depressed, the displayed frequency shifts up 1 MHz. During memory
recall operation, depressing this key recalls memory CH3.
Used to store the desired frequency in memory.
For memory input, refer to page 15.
During memory recall operation, depressing this key recalls memory CH4.
In memory CH4, transmit and receive frequencies are stored independently for
odd split operation.
When depressed, the ALERT indicator lights to show alert operation is in pro-
gress,
Depressing this key again releases this operation. For more details, refer to
page 17.
During memory recall operation, depressing this key recalls memory CH5.
Memory channel 5 is used for odd split operation as is memory channel 4.
The frequencies (transmit and receive) stored in CH5 designate frequency
range limits for programmable scan operation.
For more details, refer to page 15.
As shown in the table, this key provides three types of operation.
Mode A/B key functions
VFO Each time the key is depressed, VFO A and B are selected
alternately.
MR When depressed, the VFO frequency that was selected
before memory recall, is restored.

ed. Pin assignments of the MIC connector are shown below.

When the key is depressed initially, the common channel can be recalled
regardless for mode. This channel can be programmed to any desired frequen-
cy. For common channel programming, refer to page 15. To release common
channel operation, depress this key again. No other key will release the opera-
tion.
When the optional TU-3 or TU-3A tone unit is installed, the 1st tone frequency
is emitted when operating the COM channel.

© REV switch Used to reverse the repeater shift (+600 kHz) to monitor the repeater input.
REV Setting this switch to ON in simplex operation locks the displayed frequency
O regardless of VFO, keyboard, and COM.CH operations.
@ TX OFFSET switch Used to select the transmit frequency offset (+600 kHz) for repeater use.
For other than of a repeater operation, place this switch to the ‘’S’’ position.
This equalizes the transmit and the receive frequency.
"+" 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 an offset frequency were to go beyond the operating frequency range when
depressing the PTT switch to transmit, a beep will sound three times to indicate
an error, and the radio will transmit simplex.

ting of the TX OFFSET switch connects the TU-3 or TU-3A 2nd tone frequency
setting.

Holding the key depressed, continuously shifts the frequency up or down.
Holding the UP or DWN key depressed for about one second initiates scan
operation. The scan direction depends on the UP or DWN key operated.
Depressing the UP or DWN key during MR operation will change the opera-
tion from MR to VFO.
Press-to-talk switch is used for transmission. This will also releases scan opera-
tion. When releasing the SCAN operation, transmission is inhibited.

3. INSTALLATIONS AND CONNECTIONS
@ ANTENNA
@ MOBILE INSTALLATION
¢ Interconnection
® Installation location
The performance of the transceiver depends to a great extent upon the type of
antenna to be used. To ensure the maximum performance of the TM-201B,
select a suitable antenna and adjust it for low VSWR.
The TM-201B is equipped with an external speaker.
