this happens, replace the old battery with a new one.
• In the interests of environmental protection, do not
dispose of the battery pack improperly. Check with
your local solid waste officials for details on recycling
options or proper disposal in your area.
• It is not necessary to turn the power OFF of the
receiver while charging. However, noise may occur
during reception.
■Precaution for preventing short-circuit of battery
Be extra cautious when
carrying the battery pack; the
short-circuit will produce surge
current possibly resulting in
fire.
Put it in a non-conductive plastic bag, or wrap it
with a non-conductive material when you carry.
Protect it by
spreading a nonconductive sheet.
DON'T carry with any
type of metals. (e.g.
chains)
DON'T put it in bags
whose interior is
plated with metal.
DON'T wrap with a

Basic Operations
4.3 Adjusting Squelch Level
"Squelch" is a function for eliminating noise which you may hear
during AM or FM radio reception. This noise is a nature of
AM/FM receivers when no signals are present. "To open
squelch" means that you have the DJ-X7 receive any signals
stronger than the squelch level you adjusted.
• There are 10 squelch levels. (0-9)
• The default is set to 3.
1. Press the dial twice.
The current squelch level is displayed on the LCD.
2. Increase/decrease the squelch level by rotating the dial.
When you set it to a higher level, weak signals may be
interrupted while receiving or may not be received at all.
Generally, you should set the squelch to the lowest level where
noise is just cut.
Depending on the receiving frequencies and the conditions
around you, the squelch level needs to be adjusted.
3. Press the dial or the [F] key to conclude the setting.
The DJ-X7 also concludes the setting and returns to the normal
operating mode after no dial operation continues for 5 seconds.
■Monitor function
This is a function to open squelch compellingly. When a
receiving signal is relatively weak or is interrupted, this function
opens squelch temporarily regardless of the squelch level you
adjusted.
This is activated only when the [MONI] key is assigned to the
Monitor function in the Set mode. For more information, refer to
"(12)Monitor/Mute function setting" on P.33.
There are two options in the Monitor function: PUSH and HOLD.
Both options open squelch, and the icon appears on the
LCD while this function is ON.
• PUSH: Squelch opens while holding the [MONI] key down.
When you release the key, the squelch goes back to its
normal setting.
• HOLD: Squelch opens when you press the [MONI] key, and it
remains open until you press the key again. The squelch then
goes back to its normal setting.
You can switch between PUSH and HOLD in the Set mode. For
more information, refer to "(13)Monitor-key Operation setting" on

■Memory types
The DJ-X7 has four types of memory bank; bank for normal
memory channels, bank for programmed scan channels, bank
for skip-search channels, and bank for priority channels. "Bank"
is like a partition which separates a group of channels from
others. The following explains each bank type.
Normal memory channel
....................................Channels which are usually called up in
the Memory mode. You can program
frequencies up to 1000 channels into the
available memory banks. Editing your
favorite frequencies in advance will ease
calling them up.
Programmed scan channel
.....................................Channels which are used for the
programmed scan. You can program up
to 50 pairs of frequency ranges (higher
and lower limits) into the "PS" bank.
Skip-search channel
.....................................Channels which are skipped while
executing the VFO scan or the
programmed scan. You can program
frequencies up to 100 channels into the
"PAS" bank.
Priority channel
....................................Channels which are used for the Priority
Monitoring function. You can program
frequencies up to 10 channels into the
"Pri" bank.

Cable-clone and PC Connection
Cable-clone is a useful function for transferring the stored
memories and operating parameters from one receiver (called
as Master) to another (called as Slave) using a cable to make a
copy of the Master (original) DJ-X7.
Moreover, once you connect the DJ-X7 to your computer using
an optionally available cable, you can control and manage the
configurations or other memory settings from the computer with
free downloadable software we provide on the Internet. (For
more information, see MEMO on P.21 right hand.)
When you wish to connect to a computer, refer to "7.2
Operation for Receiving Data (on the Slave)" section.
7.1 Cable Connection
• Connect the earphone jacks on the Master and the Slave with
a 2.5ø stereo plug cable (commercially available) as shown in
the below illustration. When you connect the DJ-X7 to a
computer, use the PC interface-cable (optionally available;
ERW-4C). Plug the socket of the cable to a serial port on the
computer, and plug the other to the earphone jack on the DJX7.
• Ensure that the both receivers are OFF before the connection.
7.2 Operation for Receiving Data (on the Slave)
1. Hold the key for 1 second to turn the power ON
while holding the [MONI] key.
The following is displayed on the LCD, and the Slave enters the
Clone mode.
2. For the Cable-clone, operate on the Master at this time
with reference to the next section. For the PC
connection, launch the editing software.
After you launched the software, select the menu displayed on
the screen as you desire.
3. Turn the power OFF on the Slave after the transfer is
over or you finish the operations with the computer.
• A 2.5ø stereo plug cable should be a direct-coupled
type to avoid internal resistance.
• Even while the Master transfers data, the operation
can be suspended with any key operations on the
Slave. To restart, press the dial.
• Do not unplug the cable while cloning. Otherwise
"" is displayed on the Master's LCD, and the
Master suspends transferring.
• Note that all data stored on the Slave are overwritten
with the Master's if cloning is executed. Be sure if it's
OK before cloning.
