Step 3: Install Multi-Messager USB hardware
Step 3.1:
Wall or shelf mount the unit. Screws and rubber feet are supplied in the accessory kit.
Step 3.2:
Verify power switch on rear of unit is in OFF position. Attach the included power pack to a wall
or power strip receptacle, then attach the other end to the jack on the rear of the unit labeled 12VDC.
Tip
: Make sure the power receptacle is live 24 hours a day and is not switched off at night.
Step 3.3
: If connecting unit to an amplifer make sure it is turned OFF for this part of the installation.
Step 3.4: Connect the 10-pin socket blocks to the headers on the rear of the unit. This wiring should have been
done in a previous step - if not completed go to the WIRING DIAGRAM section of this manual (page 6).
Warning:
Connection of a P.A. amplifiers OUTPUT to any connections on this unit will cause damage and void
the warranty.
Step 3.5:
Insert the USB flash drive into the front of the unit. Do not force the USB flash drive - if it does not fit
in one way, try turning it over and reinserting.
Step 3.6: Turn the power switch on rear of unit to the ON position. After the unit initializes the STATUS LED on
the front of unit will turn solid blue. This process may take up to 15 seconds.
Step 3.7: Push the SPEAKER switch located on the front of the unit to the IN position. This speaker is for veri-
fying audio playback and testing purposes only – DO NOT use this for setting the OUTPUT volume level!
Step 3.8: If any amplifiers were turned OFF during installation turn them back ON now.
Step 3.9: If a background music source is not being fed through the unit then skip to the next step. Adjust the
volume level pot labeled BGM on the bottom of the unit using the included screwdriver. DO NOT use the internal
speaker on the unit to set this level - listen to the speaker(s) connected to the output of the unit or output of the
P.A. amplifier .
If an acceptable volume level can not be achieved or audio is distorted/muffled, then take the following steps:
a. Turn down (clockwise) the pot labeled BGM on the bottom of the unit.
b. Turn the volume level UP on the stores PA amplifier.
c. Turn up (counter-clockwise) the pot labeled BGM on the bottom of the unit.
d. Keep repeating above procedure until level is acceptable or go to step e.
e. Move the RCA plug from the 8Ω to 600Ω or 600Ω to 8Ω output on the rear of the unit.
f. Repeat step a through d.
Step 3.10:
Trigger one of the stored messages either by contact closure or timed message interval. If volume
levels are low or high, the pot labeled MESSAGE on the bottom of the unit may need to be adjusted. MES-
SAGE volume down is clockwise, MESSAGE volume up is counter-clockwise.
Step 3.11: Push the SPEAKER switch to the OUT position.
