PROBLEM
- The unit does not respond. The screen is turned off.
- The screen is on but there is no audio.
- There is poor FM reception.
- When the units power went off, some of the settings already selected were lost.
- One or several of the zones that you wish to use are not displayed on the screen.
- On entering the USB and micro SD directories, a constantly rotating hourglass is
displayed on the screen without advancing to the next screen.
- It crashes in a folder or a DRIVE ACCESS ERROR message is displayed.
- When broadcasting a message over the microphone there a deafening, high-pitched
or medium-pitched sound that stops you from being heard.
POSSIBLE SOLUTION
- Check the electric connection, check if there is a power supply and if the voltage matches the voltage selector (115 V~/230 V~).
- Press any key for a response.
- Check that the zones have an audio source (FM or MP3 or AUX) with a radio station or song selected.
- Check that the volume level is not at the minimum setting.
- Check that the speakers are connected correctly at the terminal strip.
- At the consoles rear connector, connect an external FM antenna using a shielded coaxial cable or an insulated
conductor cable of minimum 30 cm and maximum 75 cm or check that the antenna is connected correctly.
- Remove electronic ballasts or any other equipment (fluorescent lamps ) that may interfere with radio reception.
- To save changes, switch the console OFF and then ON using the stand-by key . This process allows the console
to save and memorize all of the settings and changes made.
- The relevant zones have not been registered during the SET-UP process. To register them, enter MENU, SETTINGS,
RESET and OK. This way the console will perform the SET-UP again and will ask you which ZONES you wish to activate.
- It may be due to the USB or micro SD memories being incorrectly inserted or to incorrect fragments or to the
fact that there may be a lot of files with extensions that the console cannot execute or the console may have
crashed with a DRIVE ACCESS ERROR.
SOLUTION: Press the OK key on ERROR screen or switch off the console for 2 or 3 seconds using the stand-by
key and then switch it on again. Fit the USB and micro SD cards correctly.
- It may be due to the fact that the speakers are oscillating with the microphone (LARSEN or FEEDBACK effects).
SOLUTION: Adjust the volume of the messages to a slightly lower level to avoid this noise.
SOLUTION: Move the speakers further away or change the direction of the consoles microphone.
- The speaker line or lines have an impedance of less than 4
W
or short circuit. Minimum value 4
W
.
SOLUTION: Disconnect the speaker terminal strip and use a tester to measure between
+
and
on the wired speaker lines.
If the reading is less than 3.5
W
, check the speaker impedance and volume with the number of speakers connected.
If the reading is less than 2 and close to 0
W
, check the connections and cable wiring because there is a short circuit.
Check cable filaments as sometimes
+
may be touching
.
- The console is overheating. Check that paper or other objects are not impeding the passage of air through the
ventilation grille or electric fan. Also check that the electric fan is functioning correctly and that there is nothing
blocking it.
SOLUTION: Do not place the console in a closed space such as a drawer and make sure there are no objects
on its contact surface or vent grille that may impede correct ventilation.
