Assembling and Operating Your DX15 - Quick Start
Note: While you can take your DX15 right out of the box and use it immediately with the
instructions below, the battery is shipped only partially charged. Although the Li-Ion battery used
in your DX15 does not have any "memory effects" that require a full charge before first use, we
reccomend that you fully charge your DX15 before using it for prolonged periods. See the section
Charging The Battery for details.
1 - Insure that power is OFF - rotate the PWR/VOL control counter-clockwise until it clicks.
2 - Screw the supplied antenna onto the antenna connector, clockwise, using light finger
pressure (do not tighten excessively). (Graphic showing clockwise rotation)
3 - Snap in the supplied battery pack, mating the two tabs on the bottom of the battery with the
associated slots on the battery recepticle. Gently, click the upper part of the battery into place.
(Graphic showing proper battery insertion, slots, tipping up, and clicking in.)
Operating Your DX15 - Quick Start
1. Rotate the PWR/VOL knob clockwise, adjusting the volume to the 10:00 to 2:00 position
depending on the volume desired.
2. Set the desired frequency:
- The decimal point ("."), and trailing digit is rounded to the nearest 0.025 MHz (25 KHz) and
automatically inserted onto the display, so to set a frequency of 128.775, type the following:
1 2 8 7 7
The display should then read:
128.775
To set a frequency of 122.300, type the following:
1 2 2 3 0
The display should read:
122.300
At this point, 122.300 is tuned and you are now able to transmit and receive communications on
this frequency.
To transmit, press and hold the push-to-talk button on the left side of the radio.

Charging The Battery
Your DX15's is equipped with a rechargable Lithium-Ion battery pack.
To charge your DX15:
Connect the AC-DC adapter to the DX15's DC IN as illustrated (graphic of plug being
inserted into DC In jack)
Plug the AC-DC adapter into a 110V AC outlet (graphic of wall outlet insertion)
Whenever your DX15 is connected to external power, it will charge the battery, even when your
DX15 is being used to receive and transmit. During charging the Battery Status icon will animate
to indicate that it is charging. Additionally, the bars on the interior of the Battery Status icon will
display the approximate state of the charge. When charging is complete, the Battery Status icon
be on solid and the bars will extend through the entire length of the Battery Status icon.
A fully-discharged battery will require approximately xxx hours to fully recharge via the DC IN if
the DX15's power is off. While your DX15 can be used to receive and/or transmit during charging,
such usage during charging will increase the time it takes for the battery to fully recharge.
If you are using your DX15 as a backup trasceiver that will be stored without being used for long
periods, the battery will hold its charge longest if it is disconnected from the radio. Store the
battery so that its electrical contacts are not able to be shorted by surrounding metal objects.
Charge your battery every xxx months to keep it fully charged should it be needed in an
emergency.
nlike older battery technologies, Lithium-Ion batteries do not suffer adverse affects if they are
not fully charged or discharged. As with all rechargable batteries, the usable capacity of your
DX15's battery will decrease with time and usage. Replacement batteries can be obtained from
Dynon Avionics and authorized dealers.
Basic Functions
Power On / Off
(Graphic showing PWR/VOL knob, with clockwise rotation symbol)
Power ON:
Rotate the PWR/VOL knob clockwise until it clicks. The TX/RX indicator and backlighting should
illuminate for approximately 1 second to indicate that they are working. The display will show all
icons and digits for a moment to indicate that they all work.
Power OFF:
Rotate the PWR/VOL knob counter-clockwise until it clicks.
Volume Adjustment
With power On, rotate the PWR/VOL knob clockwise to increase volume, counter-clockwise to
decrease volume.

Note: It may be useful to adjust Squelch so that the speaker is active during Volume Adjustment
- see the section Setting Squelch for details.
Transmitting
To transmit on the tuned frequency, press and hold the Push To Talk button on the left side of
your DX15 while speaking into the microphone on the front of the tranciever.
Backlight On / Off (LIG T Button)
The backlight can be turned on or off by pressing the LIGHT button at any time.
Note: The functionality of the LIGHT button can be changed affecting Backlight On / Off - see
the section Advanced Settings for details.
Setting Backlight Brightness
To adjust the brightness of the backlighting:
Push and hold the LIGHT button until it says LitE-X, where X represents the current
backlight level.
Adjust the backlight level by using the < and > buttons.
The display will show 1 through 9.
To exit, push the LIGHT or CLR button.
Setting Squelch
Squelch silences the speaker, eliminating the background noise present on all frequencies even
when no signal is being received. Squelch is adjusted to keep the speaker muted except when a
signal is being received on the frequency that is being monitored.
Note: The functionality of the side ^ and v buttons can optionally be set to adjust Squelch all
the time. See the section Advanced Settings for details. These instructions reflect the FACTORY
DEFA LT behavior of the side ^ and v buttons.
Note: Squelch can be changed in any mode or menu; upon exit of setting Squelch, the previous
menu or mode will return / continue.
To Set Squelch:
Push the SQL button
sing the < and > buttons on the keypad or the side ^ and v buttons, adjust the squelch
setting from 0 to 24.
Setting Squelch to 0 results in static being heard when no signals are being received (no
Squelch being applied). (Note: This will drain the battery more quickly.)
Setting Squelch to 24 means that only a signal that is extremely strong will break Squelch
(un-mute the seaker) and be heard.
Typically Squelch is set to the lowest setting that causes all background noise to be muted,
but allows actual signals to be received. The Squelch setting may need to be adjusted in

different environments and conditions.
Exit Setting Squelch mode by:
Pushing the SQL button on the keypad;
Pushing the CLR button on the keypad;
Waiting approximately 5 seconds;
Pushing the Emergency button;
Pushing the Push To Talk button
The previous menu or mode will return / continue.
Setting Frequency - 121.500 M z (Emergency button)
Push and hold the orange Emergency button. The digits
1 2 1 . 5 0 0
appear on the display at approximately 1/3 second intervals. When the last digit has appeared,
121.500 is tuned, and the Emergency button can be released.
Your DX15 is now ready to receive and transmit on 121.500 MHz.
Note: If the Emergency button is release before all digits of 121.500 are displayed, the frequency
will return to its previous setting.
Setting a Frequency Directly
Note: The "Assume leading 1 / 100 MHz" setting will change this behavior - see the Advanced
Settings section for details. The instructions below reflect the FACTORY DEFA LT behavior of
the "Assume leading 1 / 100 MHz" function.
If the radio is in another mode, such as Scan, Memory Recall Mode or Most Recently sed
Frequency Recall Mode, exit these modes first by pushing the CLR button on the keypad in order
to set a frequency as described below.
Example
To enter the frequency 128.775, you would enter:
1 2 8 7 7
The display should then read:
128.775
The decimal point (".") is automatically entered for you.
The last digit is automatically rounded to the nearest 0.025 MHz (25 KHz) since there is only one
possible choice for it once the first five digits are typed.
This frequency is now tuned and you can receive and transmit to other radios that are also tuned
to the same frequency.
Band Scanning
FogBugz: DX15 Manual Text
http://fogbugz/fogbugz/default.asp?pg=pgW k &command=v ew& xW k P...
12 of 29
6/23/2009 9:44 AM

Band scanning rapidly checks every frequency within your DX15's operating range of 118.000
MHz through 136.975 MHz in 0.025 MHz (25 KHz) steps (118.025, 118.050, 118.075, etc.)
sequentially. In Band Scanning mode, the DX15 will pause on frequencies that have a strong
enough signal to break squelch so that they may be heard.
To enter Band Scanning Mode:
Exit any other mode (such as MEM mode) by pushing the CLR button on the keypad.
Adjust Squelch (see section Setting Squelch for details) so that the speaker is quiet. If a signal is
received during scanning, the scanning will pause, allowing you to listen to the received signal.
When band scanning, your DX15 may receive a variety of signals at widely-varying signal
strengths. Setting Squech too high will allow only the very strongest signals to be heard. Setting
Squelch too low will result in the scan being stopped frequently, often on noisy frequencies that
cannot be understood. Thus, setting Squelch properly for band scanning will necessarily be a
compromise.
To scan up push and hold (for at least 1 second) the > button. To scan down push and hold the
< button.
During Band Scanning (or any of the other scan operations - see section Memory Scanning and
Last Ten Frequencies Scanning for details), the decimal point between the digits flashes to
indicate that a scanning mode is active.
When a signal is received that exceeds the Squelch setting, Scan Mode will pause for as long as
the signal is being received. Scanning will resume a few seconds after the last signal is received.
To force the radio to continue scanning while a frequency is being received, press either the < or
> button to "nudge" it off the frequency currently being received.
When the end of the band is reached, scanning will continue, in the same direction, from the
other end of the frequency range. The direction of scanning can be changed by pressing < or >.
Band Scanning can be stopped by:
Pushing the CLR button
Pushing PTT
Pushing the Emergency button
Keypad Lock
Keypad Lock is used to protect against accidental button pushes, such as when your DX15 is
worn on a belt and you want to monitor only a single frequency.
To activate Keypad Lock:
Press and hold the the LOCK button.
After a moment, the Keypad Lock icon will appear on the display.
Keypad Lock inhibits keypad buttons / behaviors except the following:
Push To Talk (PTT) button works normally

The LIGHT button works normally
To exit from Lock Mode
Push and hold the LOCK button until the Keypad Lock icon dissapears.
All keypad buttons / behaviors will now function normally.
Battery Monitoring
The bars on the interior of the Battery Status icon will display the approximate remaining capacity
of the battery.
graphic of various states of charge - 100/80/60/40/20 % (if it's 5 bars) or 100/75/50/25 % (if it's 4
bars)
When only one bar is displayed, very little capacity remains and you should consider charging
the battery or installing another battery.
Recalling Most Recently Used (MRU) Frequencies
Note: To use MR Frequencies, the Side buttons used for Direct Squelch behavior must be set
to OFF (factory default).
MR Frequencies are the ten (10) frequencies that were most recently used. Think of them like
an extended version of the flip flop feature on many panel-mounted aviation radios.
To recall a MR Frequency:
When in no other Memory or Scan Mode, push the ^ or v buttons on the side to enter MR
recall mode.
The first button push on either button will recall r0, which is your current frequency.
The ten (10) most Recently sed Frequencies are displayed as r0 (most recently used)
through r9 (10th most recently used).
Press ^ and v to cycle through the Most Recently sed frequencies.
MR Frequencies can be scanned by pressing and holding < or > for 2 seconds, similar to
band scanning. To stop scanning your MR Frequencies, push the CLR button.
A frequency is added to the list of MR Frequencies when:
A frequency is manually entered from the keypad
A frequency on which a signal is received for more than two (2) seconds during scanning
A frequency that was transmitted on for more than two (2) seconds
The frequency that was displayed when MR mode was entered.
Note: Any particular frequency is only stored once as a MR Frequency. Example: if 118.500 is
manually entered, several MR Frequencies are selected, and then 118.500 is manually entered
again, it will not be stored as a MR Frequency a second time.

hold (for at least 1 second) the < button.
Note: Only Memory Channels that have a frequency stored in them will be scanned.
During Memory Channel scanning (or any of the other scan operations), the decimal point
between the digits flashes at a 1/2 second interval to indicate that a scanning mode is active.
When a signal is received that exceeds the Squelch setting, Memory Channel scanning will
pause for as long as a signal is received. After signal reception ceases, Scan Mode will hold the
frequency for a few more seconds before scanning resumes. To force the radio to continue
scanning while a frequency is being received, press either the < or > button to "nudge" it off the
frequency currently being received.
When the scanning reaches Memory Channel 99 or Memory Channel 00, respectively, Memory
Channel scanning will loop to the other end of the Memory Channels and continue scanning in
the same direction.
Memory Channel Scanning will continue until stopped by:
Pushing the CLR button
Pushing PTT during the reception of a signal
Pushing the Emergency button
Skipping Memory Channels During Scanning
Some frequencies - such as ATIS and AWOS - are broadcasted on continuously. While you may
want to store these frequencies into Memory Channels for quick access to them, you may not
want them to be received during a scan. To set a Memory Channel to be skipped (Skip Tag)
while scanning:
Select a Memory Channel as described in the Recalling Memory Channels section above.
Push and hold MEM for one to two (1-2) seconds
The lock icon wil flash continuously to indicate that this Memory Channel will be skipped
during a scan.
Repeat the above procedure to allow a skipped memory channel to be scanned again. The
flashing lock icon will cease flashing.
Memory Banks
By default, all 100 Memory Channels are scanned at sequentially whenever Memory Channels
are Scanned. However, you may prefer to break up your memory channels into banks so that
only 10 of them are scanned at a time. This is useful for programming small groups of
frequencies that you scan through at a particular location, such as at an airshow or at your
favorite airports.
To turn Memory Banks on and off, see the Advanced Settings section of this manual.

When Memory Banks are enabled, only Memory Channel Scanning behavior is affected. All 100
Memory Channels can still be stored and accessed like normal. However, when a scan is
initiated, only the Memory Channels that start with the same number are scanned. For example,
if you start a scan from Memory Channel 34, only Memory Channels 30-39 are scanned.
Similarly, if you start a scan from Memory Channel 03, only Memory Channels 00-09 are
scanned.
This mode effectively divides up your Memory Channels into 10 scannable banks of 10 channels
each.
Key Beep Volume Adjustment
To adjust key beep volume:
Push and hold the SQL button until it says BEEPXX. XX represents the current key beep
volume level. You will need to continue holding the SQL button as the radio passes through
Sidetone Adjustment, which is displayed as "SideXX"
Adjust key beep volume level by using the < and > buttons.
The display will show 0 through 8; 0 is no key beeps (beeps are muted), 8 are loud key
beeps
To exit Key Beep Volume Adjustment push the SQL or CLR button
Advanced Settings
Option: Assume Leading 1 During Frequency entry: OFF (default) / ON
When this option is turned ON, the first "1" when entering frequencies is automatically typed.
This is possible because all frequencies that can be tuned by the DX15 begin with "1".
To set:
Turn power OFF.
Push and hold the 1 button.
Turn power ON.
If message "1 - off" is displayed, this behavior is OFF
If message "1 - on" is displayed, this behavior is ON
The message will clear after two seconds and you can then use your DX15 normally.
To change between modes, repeat the procedure (repeated cycles toggle between the two
modes).
Example : If set to OFF (Factory Default), the following frequency entry method is used:
To set a frequency of 128.775, type the following:
1 2 8 7 7
The display should then read:

Option: Side buttons used for Direct Squelch: OFF (default) / ON
Lets the side ^ and v be used exclusively to set Squelch.
To set:
Turn power OFF.
Push and hold the SQL button.
Turn power ON.
If message "SQL off" is displayed, this behavior is OFF. When in modes such as Setting
Squelch or Recalling Memory Channels that use the keypad < and > buttons, the side ^
and v buttons can also be used interchangably. The side ^ and v buttons are also used to
enter and cycle through ten Most Recently sed frequencies - see the Recalling Recently
sed frequencies section for details.
If message "SQL on" is displayed, this behavior is ON. The side ^ and v buttons have a
single use - to increase or decrease Squelch. In this mode, Squelch can easily be
increased or decreased with single button pushes. However, when this mode is selected,
the Most Recently sed frequencies can not be recalled.
The message will clear after two seconds, followed by a beep, and you can then use your
DX15 normally.
To change between modes, repeat the procedure (repeated cycles toggle between the two
modes).
Option: Backlight Behavior: ON (default) / 5-sec.
Sets the behavior of the backlight when keys are pressed.
To set:
Turn power OFF.
Push and hold the LIG T button.
Turn power ON.
If message "L-On" is displayed, pushing LIGHT button causes backlighting to be on
continuously until LIGHT button is pushed again.
If message "L-5SEc" is displayed, pushing any button (except Push To Talk) will cause
backlighting to come on temporarily for five (5) seconds. Pressing the LIGHT button will still
cause the backlighting to be on continuously until the LIGHT button is pushed again.
The message will clear after two seconds, followed by a beep, and you can then use your
