Unpacking and Installing the M2 Immediately upon receiving your M2, please make a careful inspection for any shipping damage. If damage is found or suspected, please notify the carrier at once and then contact your dealer. The DaySequerra M2 is shipped in one carton, which contains: the M2 unit, an AC power cable, a TorxTM T-8 L-key and this User Manual. We strongly encourage you to save the shipping carton and shipping materials supplied with your M2.
MODE - SERVICE – Default is Auto mode. Momentary push activates multicast tuning when a multicast signal is present. Holding switch in for 5 seconds when locked to an HD RadioTM station, forces monitor into Analog mode. Blue arrow LED illuminates only when switch is being pushed, or when multicast tuning or Analog mode is active. In any active mode, second push of MODE – SERVICE returns monitor to Auto mode.
DEMODULATION LEVEL SELECT – Permits user to select Left or L+R demodulated audio level to be displayed on top Demodulation Level meter, and Right or L–R demodulated audio level to be displayed on bottom Demodulation Level meter. Blue LEDs indicate the user selection of display mode. CARRIER MODULATION SELECT – Permits user to select positive, negative or both deviations to be displayed on the carrier modulation meter. Blue LEDs indicate the user selection of display mode.
When monitor has acquired any station in TUNER BAND mode and SELECT switch is held for three seconds, monitor 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.
For AM analog broadcasts, the Demodulation Level Select switch is inhibited and the monaural audio level is displayed on the Left meter; the level is calibrated from -64dB to +10dB. For FM analog broadcasts, the Demodulation Level Select switch selects the Left and Right or L+R and L–R demodulated audio levels to be displayed on the corresponding meter; blue LEDs indicate the user selection. The meters levels are peak responding between +10dB and –30dB, and average responding between –30dB and –64dB.
UP. Momentary push of UP control tunes frequency up one increment in TUNER BAND mode, when held for three seconds tunes faster. UP selects next stored preset station in PRESETS mode (no faster mode, one push per preset). Audio muting is active while tuning. Selects next item in other menus and is used for other functions as described herein. DN. Momentary push of DN control tunes frequency down one increment in TUNER BAND mode, when held for three seconds tunes faster.
The VFD will now indicate the 19kHz pilot or subcarrier frequency to be measured as illustrated in the following sample: 1 C 9 a r k r H i z e P r i t l o o t E x i t A momentary push of the SELECT switch located between the DN and UP switches will start the measurement, with the resulting level indicated on Carrier Modulation LED display. The pilot-subcarrier levels are indicated on the top meter legend. The FM stereo pilot level is typically set to 9% injection.
The VFD now displays: 5 C 7 a r k r H i z e P r i t l o o t E x i t From this point, the UP and DN switches can be used to select the next subcarrier frequency to be measured or the Carrier Modulation Select switch can be used to exit the Sub-Pilot injection level measurement mode.
HD RadioTM FM - Multicast HD-2 channel selected F S M P O R 1 T 0 S 8 . 3 H D - 2 Performance Loss Monitor Performance Loss Monitor (PLM) Connections – The PLM (standard on the M2.2R) provides six dry, floating relays with outputs on a rear panel mounted DB15 connector to report selected alarm conditions, including loss of RF carrier, program audio, OFDM lock and PAD data. The following lists the DB15 pin-outs. Relay contacts are rated at 1A @ 24VDC. Note – RBDS Loss alarm available on M2.

Pushing “SELECT” arms the alarms; monitor VFD alternates between “ALARM SET” message and normal VFD display for the station. Front panel of the monitor is locked whenever alarm is armed to prevent false alarm conditions.
