5. Setting Up

5.1 Operating Environment

1. Acceptable ambient temperature during operation ranges from
-5˚C to +40˚C.
2. Acceptable temperature during storage or shipping ranges from
-15˚C to +40˚C.
3. If condensation has formed on the equipment or the rear panel
during shipping or storage, allow the unit to acclimate for 2
hours before powering up.
4. The loudspeaker has been designed for use in a dry environment
with air of normal relative humidity and dust concentration.
Never expose the unit to aggressive chemical liquids or vapors.
5. You can position the unit at any angle. Make sure, though, to
provide at least 4 inches of free air space behind the rear panel
for adequate ventilation.

5.2 Audio Connections

1. Set all VOLUME controls (6), (9) and (12) to zero.
2. Connect the desired audio source (e.g. cassette player, CD
player) to the LINE INPUT jacks (5) using a standard cable.
3. Use a commercial XLR cable to connect your wired microphone
to the INPUT connector (8).
4. If you want to record your performance or presentation,
connect a (cassette, DAT, tape or other) recorder to the LINE
OUT jack (7) using standard jack cable.
5. For consistent audience coverage, you can use another FP-11.
Connect the LINE OUT jack (7) to the LINE IN jacks (5) of the
other FP-11.

5.3 Powering Up (Battery Operation)

The EasyPort® FP-11 has been designed primarily for battery
operation. Before first operating the EasyPort® or if the unit has
not been connected to AC power for more than a year, charge the
battery for 14 hours.
1. Plug the AC adapter into the recharge battery jack (1) on the
EasyPort® FP-11 rear panel.
Check that the AC mains voltage stated on the supplied
2.
AC adapter is identical to the AC mains voltage available
where you will use your FP-11. Using the AC adapter with a
different AC voltage may cause irreparable damage to the unit.
3. Connect the IEC cable to a convenient power outlet. Do not
use switched outlets!
Charging will start automatically and the yellow Charging LED
(2) will light constantly. When the yellow Charging LED (2)
starts flashing the battery is fully charged and the EasyPort® is
ready to operate.
4. Unplug the AC adapter from the recharge battery jack (1).
When the FP-11 is switched on (3), the LED (4) lights up
green if the power pack is fully charged.
If the power pack voltage is decreasing, the LED lights up red
continuously.
After the LED is lit for 10 seconds, the FP-11 switches off
5.
to prevent the power pack from an exhaustive discharge.
Recharge the battery as per steps 1 through 4.
Note: Depending on the load, battery operating time will be
12-18 hours.
Since the battery has no memory effect, you will not need
to discharge it fully before charging. Therefore, you can start
charging at any time irrespective of the battery`s residual
capacity.
Important: Lead batteries should not be stored for extended
periods of time in entirely or partially discharged
condition. We therefore recommend to recharge the battery
immediately after use.
In order to make sure the EasyPort® is always ready to operate,
it is best to leave it connected to AC power whenever you do
not use it.

5.3.1 Total Discharge Protection Circuit

Discharging a battery totally may cause extensive damage. We
therefore provided the electronic circuitry of the EasyPort® with an
intelligent protection circuit that effectively prevents the battery
from being totally discharged. The protection circuit automatically
isolates the entire EasyPort® electronics from the battery and
switches the loudspeakers off before battery capacity approaches
the total discharge threshold. If this happens, recharge the battery
immediately.

5.4 Powering Up (AC Operation)

The EasyPort® has been designed for an AC voltage of 230 V/50Hz.
Custom versions with an adapter for other AC voltages are available
on request.
1. Plug the supplied AC adapter into the recharge battery jack (1)
on the EasyPort® rear panel.
2. Check that the AC mains voltage stated on the EasyPort® is
identical to the AC mains voltage available where you will
use your EasyPort®. Using the AC adapter with a different AC
voltage may cause irreparable damage to the unit.
3. Connect the AC adapter to a convenient power outlet.
Important: In case the AC plug needs to be replaced with a
different type, note that this job may only be performed by a
qualified technician..
4. To power up the EasyPort® set the power switch (3) to on.
The status LED (4) next to the power switch (3) will illuminate
green.
Note: During AC operation, the charging circuit of the
EasyPort® will automatically switch to trickle charge mode.
This means that the battery will be automatically recharged
during operation. This also means you can continue operating
the EasyPort® on AC power even if the battery is completely
down.
Note: In the event of a power failure, the EasyPort® will
automatically switch to battery operation with no interruption.
Therefore you can not switch the EasyPort® on and off by
means of an external power switch or safety cut-out.
