OPERATOR CONVENIENCES
APO (Auto Power OFF)
You can set the TS-2000(X) to switch OFF
automatically if no keys or controls are pressed or
adjusted for a certain period of time. 1 minute before
the transceiver switches OFF, “CHECK” is output in
Morse code. You can select the time from OFF, 60,
120, and 180 minutes.
Press [MENU], then turn the MULTI/ CH control to
access Menu No. 57.
Select the APO time from OFF, 60, 120, or 180
minutes.
Note:
◆
The APO function works even if the transceiver is scanning.
◆
The APO timer starts counting down the timer when no key
presses, no control adjustments, and no command (RS-232C
port) sequences are detected.
AUTOMATIC ANTENNA TUNER
As explained in “ANTENNA CONNECTION” {page 1},
matching the impedance of the coaxial cable and
antenna is important. To adjust the impedance
between the antenna and the transceiver, you have
the choice of using the internal tuner or an external
tuner. This section describes how to use the internal
tuner. For the external tuner, consult the instruction
manual that comes with the tuner.
1 Select the transmit frequency.
2 Press [FUNC], [AT/ ANT1/2] to select ANT 1 or
ANT 2.
• If an external tuner is connected to the ANT 1
connector, select ANT 2 to use the internal
antenna tuner. The internal antenna tuner is
automatically bypassed if an external antenna
tuner is connected to ANT 1.
3 Press [AT/ ANT1/2] momentarily.
•“AT” appears, indicating that the internal
tuner is in-line (not bypassed).

4 Press [AT/ ANT1/2] for more than one second.
• CW mode is selected and tuning begins.
•“” blinks and the MAIN band LED lights red.
• To cancel tuning, press [AT/ ANT1/2] again.
• If the SWR of the antenna system is extremely
high (more than 10:1), an alarm (“SWR” in
Morse code) sounds and the internal tuner is
bypassed. Before attempting to tune again,
adjust the antenna system to lower the SWR.
5 See the display and check that tuning has
successfully finished.
ALT (Auto Lock Tuning)
The ALT (Auto Lock Tuning) allows the transceiver to
adjust the center receiving frequency automatically
when you operate on the 1.2 GHz band in FM mode.
When the receiving audio signal is distorted or breaking
up, turn this function on to adjust the center receiving
frequency. Some old 1.2 GHz transceivers do not have
stable and precise oscillating circuits and tend to be
slightly off (drifted from) the displayed frequency.
Press [FUNC], [XIT/ ALT] to toggle between the ALT
function ON or OFF.
• “ALT” appears when the function is ON.
Note: The ALT (Auto Lock Tuning) works only on the 1.2 GHz band
in FM mode.
ANTENNAS
HF/ 50 MHz Band
Two antenna connectors are available for the HF/
50 MHz band on the rear panel {page 13}. When you
operate the main transceiver on these frequencies,
you can select one of 2 antennas.
Press [FUNC], [AT/ ANT1/2] to select ANT 1 or ANT 2
for the main transceiver.
•“ ” or “ ” appears to indicate which
antenna is selected.
The ANT 1/ANT 2 setting will automatically be stored
in the antenna band memory. Next time you select
the same band, the same antenna will be
automatically selected.

only, then select ANT 1. The internal tuner will be automatically
bypassed when the transceiver is switched ON.
VHF/ UHF/ 1.2 GHz Band
When you select the VHF, UHF, or 1.2 GHz (TS-2000/
TS-B2000 optional) band on the main transceiver
and/or the sub-receiver, the following antenna is
automatically selected based on the operating
frequencies.

Note: The same antenna is shared and used when the main
transceiver and sub-receiver are on the same band. The frequency
coverage varies depending on the market codes.
