Set-up

1. Select one of the beltpacks to operate in master wireless

mode and plug in a headset.

2. Turn on the master-mode TR-240 beltpack.

•

If the beltpack has not been previously set to master

wireless mode, press and hold the <1> button while the

beltpack boots.

•

After approximately 20 seconds, the “master wireless”

voice prompt will be announced in the headset indicating

that communication has started.

•

The voice prompt will also announce the current RF

channel of operation, for example, “Channel 1”.

3. If the user desires to change the RF channel, continue

holding the <1> button until the voice prompt announces

“RF Selection”.

•

At this time, the user may run a ClearScan or manually

select the RF channel of operation.

4. Once the master-mode TR-240 has booted, plug headsets

into the wireless TR-240 beltpacks and turn them on, one by

one.

•

If the beltpack has not been previously set to wireless

mode, press and hold the <TALK> button while the

beltpack boots.

•

Allow a few seconds between each beltpack power on.

•

After approximately 20 seconds, a voice prompt will

announce “wireless” in the beltpack headphones

indicating that wireless communications has started.

Master Wireless Mode Capacity Limit

Up to 8 full-duplex wireless beltpacks can be used with a single

TR-240 in master mode (9 total beltpacks) for reliable and

uninterrupted communications on a clear RF channel. Many more

half-duplex beltpacks can be used.

If a master-mode TR-240 is loaded beyond it’s capacity limit, the

usability becomes highly subjective. The users will begin to

experience drop outs and potentially delays in the audio.

NOTE: The capacity limit may not be achieved if there is

interference on the RF channel of operation. For further

details, refer to Wireless Interference in Section 10.

Tour Group Example

A good example of a master wireless mode application is a tour

group within a noisy manufacturing environment.

As shown in Figure 7-5, a single TR-240 is set to boot in master

wireless mode. This beltpack would be worn by the tour guide.

The rest of the beltpacks are set to boot in wireless mode. They

are all kept in half-duplex mode by having their talk mode set to

“momentary-only”. The members of the tour group would wear

these beltpacks.

The group size could be up to 28 people (or more) when the

beltpacks are in momentary-only mode. This is because when in

momentary-only mode, the beltpack is half-duplex until the

<TALK> button is pressed activating the microphone path. When

the <TALK> button is pressed, the beltpack becomes full-duplex

and will transmit continuously until the user releases the

<TALK> button. A maximum of 8 members of the group could

push their <TALK> buttons and talk at once.
