GENERAL SETUP AND OPERATING HINTS
1. DISTANCE.
To maximise operating distance (approximately 100m). We recommend
you follow the following guidelines.
a. Ensure good line of sight between Transmitter and Receiver. Do not place
large obstructions between receiver and transmitters e.g. Concrete walls,
large metal obstructions. In addition keep the receiver away from metallic
beams and obstructions as these can adversely affect the Antenna Pick-up
Pattern and induce interference.
b. Always ensure that the Transmitter is at least 3m (10 feet) away
from the Transmitter.
c. Conduct a “Walk test” which involves you moving the Transmitter in the
area transmission is required and noting the received RF signal strength on
the receiver bargraph. Reception is best with all 4 Leds lit.
d. Never position the Transmitter Antenna directly against the body or hand.
This will have the effect of reducing the operating range considerably.
2.
MULTICHANNEL OPERATION OF THE WS.
The WS is designed for simultaneous use of four systems.
a. Ensure each system is assigned a different operating channel. The
channels are adjusted as per the illustrations. It is important that each
Transmitter/Receiver combination has it’s own unique channel numbered 1-4.
Note: The Transmitter only changes Active Channel when turned off and then on.
b. We recommend that the Receivers are spaced slightly apart and not stacked
directly on top of each other to avoid disturbance to the Receivers
Antennae.
c. Try to ensure that each Transmitter is separated by 0.5m (1.5 feet) during
operation.
Note: TOA cannot guarantee multichannel compatibility with other brands/make
of product.
3.
SQUELCH/RSSI SET UP.
The WS incorporates a
F
ixed
N
oise
Squelch and a variable “Received
Signal strength” Mute Control on the rear panel of the Receiver. This
function is to reduce or eliminate the effect of interference from
outside sour
ces.
To adjust follow these steps:
a. Turn-off the Transmitter and note if any interference is present by
monitoring the Receiver RF Bargraph or Audio Output.
b. Turn the Squelch Control clockwise until the interference disappears.
In extreme cases it may not be possible to remove the unwanted
interference and in this case it is recommended you try an alternative
channel.
Note: that the Squelch Control affects the operating range of the system and with the
Squelch set to maximum, the range will be significantly reduced.
4.
RECEIVER AF GAIN ADJUST.
The WS receiver gain is continuously adjustable between Mic and
Line level.
Should the receiver signal be too high it will distort your mixer/amplifier.
If the signal is too low the result will be an increase in general
background noise.
Adjust this control to achieve the best signal quality.
5.
BATTERY INFORMATION.
Please note that this product is designed to be used with a 9V Alkaline
battery. Should you use a rechargeable cell, be sure not to force it into the
battery compartment as some types can be considerably larger than
standard types and note that the operation time will be much reduced.
6.
LOW-BATTERY STATUS INDICATOR ON TRANSMITTERS.
In normal circumstances, with the use of an Alkaline 9V battery, the
Transmitters should provide approximately 10hrs of continuous use.
Should the Battery indicator go out, it is advisable to change the battery
as soon as possible.
FAULT-FINDING.
In the event of a problem it is worth checking the following check list.
1.
No RF Signal Indication on Receiver!
a. Is the Receiver and Transmitter on the same channel?
b Is the battery fresh in the Transmitter and the battery indicator lit?
2.
No Audio Signal!
a. Is the AF Gain Control set correctly on the Receiver?
b.
Is the
Squelch Control set correctly (Normally mid-position).?
c. Is the MIC/INST switch in the correct position on the Beltpack?
