the tuner displays the hardware and software version for your M4 to be displayed for 3 seconds on the
M4’s VFD.
8 M4 User Manual
In any mode, if the SELECT and DN switches are depressed simultaneously for 5 seconds, tuner goes
into Standby mode with all front panel controls and indicators inoperative except for SELECT and UP
switches; the M4’s VFD then indicates the “DaySequerra Standby” message. Holding SELECT together
with UP switch in for 5 seconds when in standby mode re-activates all front panel controls and
indicators and returns tuner to normal operation.
Front Panel Locked. In any mode, if SELECT and MODE – SERVICE switches are depressed
simultaneously for 5 seconds, tuner goes into Front Panel Locked mode; i.e., all front panel controls are
inhibited except for UP and SELECT switches; analog and digital audio outputs continue. VFD
alternates between displaying FRONT PANEL LOCKED and normal display for tuned station.
Momentary simultaneous push of SELECT and UP switches in Front Panel Locked mode restores all
front panel controls and indicators, and returns tuner to normal operation. VFD displays “Exiting Front
Panel Locked Mode” message during tuner state transition.
Audio Muting. The M4’s audio output can be set to automatically mute for received signals with signal
strength less than 45dBf. The audio muting can be enabled using the DATA - DISPLAY menu
described previously.
Tuner Band Control. TUNER BAND control toggles between manual AM and FM tuning. TUNER
BAND arrow LED illuminates only when mode is active. Audio muting is active while tuning.
Presets Control. In PRESETS tuning mode tuner has ability to store 20 AM stations and 20 FM
stations including FM-HD multicast signals.
Preset stations are stored for recall in positions A1 through A20 and F1 through F20 respectively for
AM and FM bands. PRESETS Arrow LED illuminates when tuner is in PRESETS tuning mode. UP and
DN scroll through the preset stations stored for the band selected. Audio MUTING is active while
scrolling through preset stations. Second momentary push of PRESETS switch changes tuner band.
When tuner has acquired any station and SELECT switch is held for three seconds, tuner enters
PRESETS store mode and PRESETS arrow LED flashes. UP and DN controls then allow user to scroll
through A1 through A20 and F1 through F20 dependant on band. When the desired preset location is
indicated on VFD, next momentary push of SELECT switch stores selected station in that PRESETS
position.
Mode - Service Control.MODE - SERVICE control selects AUTO or ANALOG mode, and activates
multicast tuning when an HD RadioTM multicast signal is present. In the AUTO mode, the tuner will
receive an HD RadioTM digital broadcast if one is being transmitted; if not, the tuner will receive the
analog broadcast. The MODE - SERVICE LED illuminates when only the mode is active or when the
switch is being pushed. Default mode is AUTO.
When tuned to an HD RadioTM broadcast and at least one multicast signal is present, momentarily
depressing the MODE – SERVICE switch selects the multicast tuning mode; the M4 is automatically
tuned to the first multicast broadcast, probably HD-2. The UP and DN controls can then be used to tune
to the other multicast stations; i.e., HD-3 through HD-8, available on that RF frequency.
When tuned to an HD RadioTM broadcast and the MODE - SERVICE switch is depressed for 5
seconds, the tuner is forced into ANALOG-only mode; the M4 is then locked only to the analog
broadcast signal and the audio outputs provide only the analog portion of the HD RadioTM broadcast.

left analog program audio in the M4 left channel and the left HD RadioTM audio program in the M4 right
channel. This mode provides for audio phase matching as well as audio level and time-alignment of
the HD RadioTM broadcast for the correct analog diversity delay. FORCING arrow LED illuminates
when tuner is in FORCING mode. Subsequent momentary push of FORCING switch turns FORCING
mode and FORCING LED off. Default mode is off.
When tuned to an HD RadioTM broadcast and the FORCING switch is depressed for 5 seconds, the
tuner is forced into HD-1 DIGITAL-only mode; the M4 is then locked only to the HD-1 broadcast. There
is no DIGITAL-only mode for multicast broadcasts.
Data – Display. The DATA - DISPLAY control provides display of RBDS PS and RT fields (M4.2R
only) as well as PAD data for HD RadioTM signals. DATA - DISPLAY arrow LED illuminates when
mode is active. DATA - DISPLAY switch selects RBDS from the current analog broadcast or PAD data
from the current HD RadioTM MPS (HD-1) or HD-2 through HD-8 multicast signal to be displayed on
tuner’s VFD. Momentary push scrolls through each PAD field in the following sequence:
•Station long name
•Station program type
•Song title
•Artist
•Album
•Genre
•Comment
Subsequent momentary push of DATA - DISPLAY switch turns DATA - DISPLAY mode and DATA -
DISPLAY LED off. The second line of VFD display scrolls if the message is longer than 16 characters.
If there is no data for the selected field, VFD displays “NO” plus the data category; e.g., “NO ALBUM
DATA.”
In the M4.2R, RBDS PS and RT fields are displayed per RBDS specifications. Station long name,
station short name and program type are processed as an ID3 tag. In all M4 models, HD RadioTM PAD
data; i.e., song title, artist, album, genre and comment fields are limited to 127 bytes each for a total of
