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
P.33.
