(1) LOCATION
Select a location for the transceiver that does not interfere with driving in any way. We recommend the location shown in the figure below.
After mounting the transceiver, be sure all screws have been tightened.
Use a 13.8 V DC power source with more than 6 A capability. The optional PS-45 AC POWER SUPPLY is suitable for base station operation.
When using the transceiver as a base station, make sure a ground terminal of the power supply is grounded. Use the heaviest gauge wire or strap available and make the connection as short as possible.
(5) ANTENNA LOCATION
To obtain maximum performance from the transceiver, select a high-quality antenna and a and location
A Type-N antenna connector is used for the
1) Slide the nut, washer, and rubber gasket over the coaxial cable and cut the end of the
cable evenly.
2) Cut and remove 15 mm of the outer vinvl jacket and fold the braid back over the clamp. The clamp end should be flush with the end of the vinvl jacket. Evenly trim the
Cut and remove 6 mm of the dielectric (the center conductor insulation)
The IC-1201A/E has 4 different modes for versatile multi-function operations.
This mode is used for normal operations over the entire band.
This mode is used for operating the transceiver using memory channel contents. You can use 20 memory channels for programming (i.e., repeater frequencies, your ground frequency, etc.).
This mode provides 1 call channel operation separate from the memory channel. You can program the most often used frequency into this

5-1 FREQUENCY SETTING
The frequency can be set with the TUNING CONTROL or the [UP] or [DN] switch on the microphone.
NOTE: When the decimal point disappears the TUNING CONTROL does not change the operating frequency since the BIT or VXO function is activated. In this case, push the TUNING CONTROL to turn OFF the function (n. 17)
4) Push the [SET] switch again.
5) Rotate the TUNING CONTROL to select MHz tuning step increments as shown below:

STEP INCREMENT |
---|---|
1.000 | 1 MHz |
5.000 | 5 MHz |
10.000 | 10 MHz |
6) Push the [VFO/M] switch to set increments and to return to VFO mode.
2) Transmit.
When you want to contact a station through a repeater, set the transceiver to duplex. To access a repeater which requires a tone, see below.
"DUP-" : Transmit freq. = Receive freq. - Offset freq. "DUP" : Transmit freq. = Receive freq. + Offset freq.
Push the [T/T.SQL] switch to turn the subaudible tone encoder ON and OFF.
"T" appears on the FUNCTION DISPLAY.

6-2 MEMORY OPERATIONS
The transceiver has 20 memory channels. Each memory channel independently stores an operating frequency, offset frequency, subaudible tone frequency (the IC-1201A or IC-1201E with the optional UT-40), and memory skip function.
(1) MEMORY READING
1) Push the [VFO/M] switch to select MEMORY mode.
• "M" appears on the FUNCTION DISPLAY.
In MEMORY mode
Copy and transfer the displayed memory contents into VFO. This function is useful for searching for signals around the memory channel frequency.
The memory channel contents are not erased.
6-3 SCAN FUNCTIONS
(1) PROGRAMMED SCAN
There are two scan functions: programmed scan and memory scan. The memory skip function can be used with memory scan.
The programmed scan function scans between two frequencies.

priority watch is activated. (p. 24) scan edge A and B are equal. (p. 21)
SETTING SCAN EDGES
1) Select VFO mode. (p. 11)
The memory scan function scans all memory channels in succession. To skip certain channels, use the memory channel skip function. (p. 23)
This function is used to skip memory channels you do not wish to scan during memory scan.
The memory skip function can also be used for priority watch (VFO ↔ memory channels). (p. 24)
Programmed as a skip channel.
(1) VFO ↔ MEMORY OR CALL CHANNEL
Every 5 sec., priority watch monitors a frequency you programmed while you operate on the VFO frequency.
Priority watch can also watch each memory channels in approx. 5 sec. consecutive intervals.
6-5 CALL CHANNEL MODE
The transceiver has an independent CALL CHAN-NEL mode which provides easy selection of your most used frequency.
CALL CHANNEL mode can be selected from VFO and MEMORY modes.

The display shows that been is ON.
The speaker emits a beep tone each time a switch is pushed. Turn ON or OFF beep tones as follows:
This function deactivates the TUNING CONTROL and switches on the front panel.
2) Push the [LOCK] switch again to unlock.

Install the optional UT-40 TONE SQUELCH UNIT for pocket beep and tone squelch functions.
CAUTION: Turn OFF power and disconnect the DC power cable before removing covers from the transceiver.
The pocket beep function alerts you using 30 sec. beep tones and "SQL" flashing when a signal with the same subaudible tone as pre-programmed is received The optional UT-40 is necessary
NOTE: Some repeaters are equipped with filters that filter out subaudible tones. Using the pocket beep or tone squelch function when contacting other stations may not always be possible.
When a signal with the same subaudible tone as pre-programmed is received, the squelch opens. The optional UT-40 is necessary

The IC-1201A/E has a lithium backup battery for retaining memory information.
The usual life of the backup battery is approximately 5 years. When the battery is exhausted, the transceiver transmits and receives normally but the transceiver cannot retain memory information.
NOTE: Battery replacement should be done by an authorized Icom Dealer or Service Center
When the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth. Avoid the use of chemical agents such as benzine or alcohol as they may damage the surfaces of the transceiver.
Your IC-1201A/E has been thoroughly adjusted and checked at the factory before being shipped. Your transceiver warrnaty does not cover problems caused by unauthorized internal adjustments.
