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), (22), (9) and (12) to zero.
2. Connect the desired audio source (e.g., cassette player, CD
player) to the LINE INPUT jacks (5) or (23) using a standard
cable.
3. Use a commercial XLR cable to connect your wired microphone
to the INPUT connector (8) or (26).
4. If you want to record your performance or presentation,
connect a (cassette, DAT, tape or other) recorder to the LINE
OUT jack (7) or the mix-out jack (25) (turn switch (24) in the
„mix-out" position) using standard jack or XLR cable.
5. For consistent audience coverage, you can use another FP-22
modular. Connect the LINE OUT jack (7) or (25) to the LINE IN
jacks (5) or (23) of the other FP-22 modular.

5.3 Powering Up (Battery Operation)

The EasyPort® FP-22 modular 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 IEC cable into the recharge battery jack (1) on the
EasyPort® FP-22 modular rear panel.
2. Check that the AC mains voltage stated on the supplied AC
adapter is identical to the AC mains voltage available where
you will use your FP-22. 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. EasyPort® is ready to operate.
5. Unplug the IEC cable from the recharge battery jack (1).
When the FP-22 modular is switched on (3), the LED (4) lights
up green if the power pack is fully charged.
When the power pack falls below 30% capacity, the LED starts
to flash red.
If the power pack voltage is decreasing, the LED flashes red
increasingly quickly until it lights up red continuously.
After the LED is lit for 10 seconds, the FP-22 modular switches
off to prevent the power pack from an exhaustive discharge.
A signal sounds when the FP-22 modular switches off.
Recharge the battery as per steps 1 through 4.
F
Depending on the load, battery operating time will be
8-18 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.

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 made 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.
