Basic Operation

Easy Mode and Expert Mode
The DJ-X2 has two operating profiles; Easy mode and Expert mode.
In Easy mode, key operations are limited, and you can operate the DJ-X2 easi-
ly. On the other hand, you can operate many useful functions in Expert mode. 
If you are a beginner, operating in Easy mode is recommended. After under-
standing basic operations in Easy mode, you may try to operate other functions
in Expert mode.
(The factory setting is Easy mode.)
This chapter explains basic operation of the DJ-X2.
Power Switch
Before turning the power ON, check the position of the Battery selection switch. 
EXTERNAL (upper) ·······················When using external batteries (EDH-27).
BATTERY (lower)···························When using the internal lithium-ion battery.
To turn the power ON, slide the power switch to PWR ON (right). HELLo will
appear on the display. (The indication may be different from the illustration
below depending on the version: North America or Europe.)
TipWhen the lithium-ion battery is charged, you can operate the DJ-X2 without the
battery case (EDH-27).
Caution!Be sure to turn the power OFF when switching the Battery selection switch.

Basic Operation
Adjusting the Audio Volume
1Press the [VOL/SQL (SET)] key.
voL will appear on the display.
2Adjust the audio volume by pressing [s / t] keys.
There are 21 levels of audio volume. (00-20) As the value increases, the
audio becomes louder.
3Press the [FUNC/ENTER] key.
If the DJ-X2 makes no sound...
When the squelch closes, the DJ-X2 does not make sound even if you increase
the value of audio volume. For more information, see the next section.
Squelch
The squelch silences the DJ-X2 except for signals above a certain level.
Squelch eliminates noise when the DJ-X2 receives less than a certain level.
To unmute the squelch means that the DJ-X2 receives a signal and repro-
duces the sound.
Conversely, to close the squelch means that the DJ-X2 does not generate
audio because of insufficient signal level.
nAdjusting the Squelch Level
You can specify the signal level at which the DJ-X2 unmutes by adjusting the
squelch level.
1Press the [VOL/SQL (SET)] key twice.
SqL will appear on the display.

2Adjust the squelch level by pressing [s / t] keys.
There are 6 squelch levels. (0-5) A higher squelch level requires a stronger
signal to unmute the squelch.
3Press the [FUNC/ENTER] or [VOL/SQL (SET)] key.
TipTo keep the squelch open, set the squelch level to 0.
nMonitor Function
The monitor function temporarily unmutes the squelch. This is useful when the
desired signal is weak or intermittent.
1Press the [MONI (SCRT)] key.
The DJ-X2 unmutes the squelch while the key is held down.
2To return to the set squelch level, release the [MONI (SCRT)] key.
The preparation for receiving a signal has been finished. Now, try to adjust the
frequency and receive a signal.
Next section explains the three operating modes of the DJ-X2.

Basic Operation
Operating Mode
The DJ-X2 has three operating modes; VFO mode, Preset mode, and Memory
(MR) mode.
VFO mode ·····································VFO mode allows you to change the fre-
quency by [s / t] keys.
Preset mode ··································The frequencies of AM radio, FM radio, and
TV have been set. You can call them up. 
Memory mode ·······························You can call up and receive a previously
programmed frequency.
TipIn Easy mode, you cannot program a frequency. To program a frequency, switch
the DJ-X2 to Expert Mode. For more information, see Switching to Expert Mode
(P.29) and Memory Function (P.30).
nSwitching Between Modes
Every press of the [V/P/M (MW)] key changes the operating mode as shown
below.
TipWhen nothing is programmed in Memory mode, Memory mode is skipped.

Setting the Frequency
nIn VFO mode
· Pressing the [s / t] keys increases or decreases the frequency by a tuning
step.
· To increase/decrease the frequency by 1MHz-step, hold down the [1MHz
(ANT)] key, and press the [s / t] keys.
· To increase/decrease the frequency by 10MHz-step, hold down the [10MHz
(BANK)] key, and press the [s / t] keys.
nIn Preset mode
1Select a band by pressing the [10MHz (BANK)] key.
Every press of the [10MHz (BANK)] key changes the band as shown below:
AM radio ÝFM radio ÝTV ÝAM radio ···.
2Increase/ decrease the frequency by pressing the [s / t] keys.
Tip· When selecting AM radio, AM appears on the upper part of the display.
· When selecting FM radio or TV, WFM appears on the upper part of the dis-
play, and the FM radio frequency or TV channel is displayed below.

Basic Operation
Scan Function
The scan function periodically changes the frequency to serarch for a signal.
The DJ-X2 has four types of scan functions.
VFO scan ······································Scans the entire band in VFO mode.
Preset scan ···································Scans the entire band in Preset mode.
Program scan································Scans a specified range of frequencies. The
upper limit and lower limit of the range need
to be set in advance.
Memory scan ································Scans specified memory banks.
nVFO scan
1Switch to VFO mode by pressing the [V/P/M (MW)] key.
2Press the [SCAN (MODE)] key.
VFO scan starts, and . (decimal point) flashes on the display.
Scanning pauses when the DJ-X2 receives a signal.
nPreset scan
1Switch to Preset mode by pressing the [V/P/M (MW)] key.
2Select AM radio, FM radio, or TV by pressing the [10MHz (BANK)] key.

3Press the [SCAN (MODE)] key.
Preset scan starts, and . (decimal point) flashes on the display.
Scanning pauses when the DJ-X2 receives a signal.
nProgram scan
This function scans a specified range of frequencies. Before operating this
function, you need to specify the upper and lower frequency limits. These fre-
quencies are called a Program channel, and the DJ-X2 has 20 pairs of pro-
gram channels.
Set the combination of upper and lower limits. (i.e. A00 and B00, or A01 and
B01) For more information, see Programming a channel. (P.30)
To operate Program scan:
1Switch to the VFO mode by pressing the [V/P/M (MW)] key.
2Press the [PS (STEP/SKIP)] key.
A program channel will appear on the display.
3Select a program channel by pressing the [s / t] keys.
Frequencies between A and B of the same No. will be scanned.
For example, if you select A01, scanning starts from A01 to B01.
Conversely, if you select B01, scanning starts from B01 to A01.
