AKG Acoustics WLS 8060 MAX - Manual (Page 6)

2. Tighten the fixing nut on each antenna CW.
3. Point both antennas upward so that the two antennas will
form a ”V”.
If you cover the WLS 8060 with the optional RP 6060 rain
cover point the antennas straight down.
5.4. Powering Up (Battery Operation)
The WLS 8060 has been designed primarily for battery
operation.
Before first operating the WLS 8060 or if the unit has not
been connected to AC power for more than a year, charge the
battery for 18 hours.
1. Plug the DC cable on the supplied AC adapter into the
RECHARGE BATTERY jack (1) on the WLS 8060 rear panel
(see fig. 1).
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
WLS 8060. Using the AC adapter with a different AC volt-
age may cause irreparable damage to the unit.
3. Connect the AC cable on the AC adapter 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 WLS 8060 is ready to operate.
4. Unplug the DC cable of the AC adapter from the RECHARGE
BATTERY jack (1).
5. To power up the WLS 8060 set the POWER switch (3) to
ON.
The STATUS LED (4) next to the POWER switch (3) will illumi-
nate green.
If the STATUS LED (4) lights red the battery is down. The elec-
tronic circuitry and the loudspeakers will switch off auto-
matically. Recharge the battery as per steps 1 through 4.
Note: Depending on the load, battery operating time will be 10
to 14 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 WLS 8060 is always ready to
operate, it is best to leave it connected to AC power when-
ever you do not use it.
5.4.1. Total Discharge Protection Circuit
Discharging a battery totally may cause extensive damage. We
therefore provided the electronic circuitry of the WLS 8060 with
an intelligent protection circuit that effectively prevents the battery
from being totally discharged. The protection circuit automatically
isolates the entire WLS 8060 electronics from the battery and
switches the loudspeakers off before battery capacity approaches
the total discharge threshold. If this happens, recharge the battery
immediately.
5.5. Powering Up (AC Operation)
The WLS 8060 has been designed for an AC voltage of
230 V/50 Hz. Custom versions with an adapter for other AC
voltages are available on request.
1. Plug the DC cable on the supplied AC adapter into the
RECHARGE BATTERY jack (1) on the WLS 8060 rear panel
(see fig. 1).
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
WLS 8060. Using the AC adapter with a different AC volt-
age may cause irreparable damage to the unit.
3. Connect the AC cable on 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 WLS 8060 set the POWER switch (3) to
ON.
The STATUS LED (4) next to the POWER switch (3) will illumi-
nate green.
Note: During AC operation, the charging circuit of the WLS 8060
will automatically switch to trickle charge mode. This means
that the battery will be automatically recharged during oper-
ation. This also means you can continue operating the
WLS 8060 on AC power even if the battery is completely
down.
Note: In the event of a power failure, the WLS 8060 will auto-
matically switch to battery operation with no interruption.
Therefore you can not switch the WLS 8060 on and off by
means of an external power switch or safety cut-out.
6. Operating Notes
6.1. Wireless Microphone
In order to prevent unnecessary noise, tune the transmitter and
receiver to the same carrier frequency prior to powering up
and inserting batteries.
6.1.1. WLS 8060 Placement
Reflections off metal parts, walls, ceilings, etc. or the shadow
effects of musicians or other people may weaken or cancel the
direct transmitter signal.
For best results, place the WLS 8060 as follows:
1. Place the WLS 8060 near the performance area (stage). Make
sure, though, that the transmitter will never get any closer to the
receiver than 10 ft (3 m). Optimum separation is 16 ft. (5 m).
2. There should always be a direct line of sight between the
transmitter and receiver.
3. Place the WLS 8060 at least 5 ft. (1.5 m) away from any big
metal objects, walls, scaffolding, ceilings, etc.
