Power Supply
The ATS-405 operates on 4 x UM-3 (AA Size, LR6)
batteries also powered by external AC power adapter
of 7.5V/0.75A (supplied) or external DC power adapter
of 7.5V/0.75A with center pin positive for China and
Taiwan (supplied).
Press and remove battery cover in the direction
indicated by the arrow on the cover. Insert 4 x UM-3 (AA
size, LR6) batteries with polarity shown on the radio
cabinet. Slide battery cover back into place in direction
of arrow until case snaps into place.
Batteries is to be replaced when battery power level
indicator drops or display flashes empty battery level.
Replace the batteries as soon as possible though the
receiver equips with a super capacitor for memory and
time back up.
Battery operation using rechargeable
1. Remove the battery cover on the back of the unit by
sliding the cover in the direction of the arrow.
2. Slide the CHARGE switch located in the bottom side
of radio to ON position.
3. Insert four Rechargeable UM-3 (AA size, LR6) batteries
into the battery compartment. Take care to ensure all
batteries are inserted with the correct polarity as shown
on the back of the radio. The radio is designed to be
used with Nickel Metal Hydride (NiMH) rechargeable
4. Plug the mains adaptor into your radio and then plug
the adaptor into the mains.
5. The battery charging LED will flash red indicating
batteries are charging. Batteries will be fully charged
in around 7 hours depending on battery capacity. The
charge LED shows a steady red when the battery
charging is completed.
● Important:
when using rechargeable batteries the battery
switch must be placed in the ON position.

band button to cycle through meter band until required
meter band is located or press and hold SW meter band
button until display flashed METER, Press Tuning UP/
Down button to allocate required meter band. Follow the
manual tuning and scan tuning methods as described
above to tuning and store the stations.
Menu operation
Through the Menu setting, you can adjust tuning
settings to achieve tuning ways that you like under
different circumstances for best performance.
This is normal that background noise or static presents
to some degree at different locations. It is best to set the
squelch level as low as possible in order not to miss the
weak transmissions.
Squelch can be set either radio is on or off. To adjust the
squelch level, press and hold Menu button until a beep
sounds and display Menu icon appears. Press Squelch
button, display SQUELCH will flash. Using the tuning
UP/Down buttons to select required squelch level, then
press ENTER button to complete the Squelch level
setting. The radio will tune and stop at the signals above
the squelch threshold only.For example, if you select
squelch level at 6, when you tune the radio, it will stop
at the stations which signal level are above 6.
Initial setting is at OFF.
Squelch level setting should be adjusted separately in
different wavebands.
Tuning Mute (T. MUTE)
If you prefer to mute the scan noise, you can select
Tuning Mute. The initial Tuning Mute is ON for all bands.
However for listeners who prefer not to miss any weak
transmissions during the tuning, you can disable tuning
mute function.
Tuning Mute can be set either radio is ON or OFF.
Press and hold Menu button until a beep sounds and
display Menu icon appears. Press Tuning Mute button 2,
display will first shows ON. Using the tuning UP/Down
button to select Tuning Mute ON or OFF, then press

signal, however it will also reduce radio reception. The
initial setting for Soft Mute is OFF.
Soft Mute can be set either radio is ON or OFF. Press
and hold Menu button until a beep sounds and display
Menu icon appears. Pressing Soft Mute button, display
will appear OFF. Using the tuning UP/Down button
to select Soft Tuning ON or OFF, then press ENTER
button to complete the setting.
Change MW (AM) tuning step-9K/10K
In Europe and most other parts of the world, MW (AM)
tuning step is 9kHz. In Northern and Latin America, MW
(AM) tuning step is 10 kHz.
MW (AM) tuning step can be set either radio is ON or
OFF. Press and hold Menu button until a beep sounds
and display Menu icon appears. Press 9k/10k button,
display will appear MW and flash 9 (kHz) or 10 (kHz) for
Northern American version. Using the tuning UP/Down
button to select 9 or 10, then press ENTER button to
complete the setting.
Change FM tuning step-STEP
FM tuning step varies in different countries.
FM tuning step can be set either radio is ON or OFF.
Press and hold Menu button until a beep sounds and
display Menu icon appears. Press Step button 5, display
will appear FM and flash 100 (kHz). Using the tuning
UP/Down button to cycle through 100/200/50 (kHz),
then press ENTER button to complete FM tuning step
Set the AGC (auto gain control)
In AM band (MW and SW), if the volume level
changes too rapidly during listening, you can delay the
responding by setting AGC IF (intermediate frequency)
1. AGC is for AM (MW/SW) only
2. AGC function is set the IF(intermediate frequency)
gain, it has 3 selection by 50db/auto/30db
2-1 "Auto" selection is the defaulted AGC level which
has a balanced gain for reception, recommended
set on auto for general purpose.
2-2 select 50 db to have a higher IF gain than the "auto",
it can amplitude weak signal 10dB more than auto,
the background noise will be enlarged, but easy to
make the signal saturate under a stronger signal.
In addition the soft mute may not be active because
of more background noise.
2-3 choose 30db to have a lower IF gain then the
"auto", once if you prefer to receive the stronger
signal only, reducing the IF gain is able to reject
the weak signal and background noise.
Auto clock time adjustment by RDS-CT
You can enable auto clock time adjustment by RDS
(Radio Data System) CT function. Clock time can be
automatically adjusted by FM RDS station.
RDS function is mostly available in European countries
and part of Northern America area.

until a beep sounds and display Menu icon appears.
Press button 0 to check software version e.g. 1.53. It is
for factory production purpose only.
Bandwidth selection (B-W)
1. Narrow bandwidth can get lower noise and higher
sensitivity while wide bandwidth can bet better
frequency response under stronger RF signal.
2. The filtering bandwidths are listed on below table.
While receiving FM RDS station, the bandwidth will
be automatically adjusted to wide bandwidth
3. While radio is on, select required waveband, press
B-W button to cycle through Bandwidth from wide,
normal (for SW and MW wavebands only) and narrow.
On display, bandwidth icons will change accordingly
and you can fell the difference on the noise and
reception while changing the bandwidth.
When listening to AM/SW/FM broadcasting, this switch
adjusts the receiver's sensitivity.
When you listen to a strong station and the signal is
slightly distorted, set the switch to the LOCAL position
for best reception. For normal or weak stations, set the
