Antenna
This small antenna is very flexible and non-
removable. For optimum performance keep the
antenna clear from obstacles.
11
POWER on/off switch
With this switch the battery power of the WS-19 is
switched on and off.
12
CHANNEL SELECT switch
With this switch the TX/RX channel (see section 8)
is selected on which the beltpack communicates
with the base station. There is a choice out of 8
TX/RX channels. The selected TX/RX channel
must match the selected TX/RX channel at one of
the TX/RX modules in the base station.
13
ASL CHARGER connector
To this connector the ASL charger unit is
connected.
On the charger unit two LED‟s
indicate the charging process. The red LED is lit
during charging, the green LED is lit when the
batteries are full.
Before starting the charging process,
make sure that the beltpack is switched
off (see #11) and check whether the
batteries inside the beltpack are indeed
of the rechargeable NiMh type. Trying to
charge non-rechargeable batteries
causes leakage of these batteries,
resulting in serious and in most cases
not repairable damage to the
electronics of the beltpack.
Use only the by ASL supplied battery
charger. Never try to use any other
adapter or charger unit.
14
HEADSET connector
To this XLR-4 connector a headset can be
connected. The headset can must have an
impedance of minimum 200 ohms. If there are 2
cans in parallel, each can must have an
impedance of minimum 400 ohms.
The headset mic may be dynamic or electret.

Service connector
For factory service only.

Battery Compartment
This compartment holds 6 penlight batteries of
the AA type. The supplied NiMH batteries are to
be preferred for maximum duration. The WS 19
uses a high discharge current which the batteries
need to sustain over their lifespan. Batteries
which only supply a high current for a short time
will be exhausted very quickly. When the batteries
reach the end of their capacity, the beltpack gives
a warning signal (4 tones). The interval of the
tones shorten when the batteries wear out.
