TR-800 Top Panel

1. On/Off & Vol ume Con trol – Turns the beltpack power

on and con trols head set vol ume.

2. Wire less Talk Around (WTA) – When pressed, the user’s

au dio is dis con nected from the wired in ter com, aux il iary

in put/out put and the base sta tion’s lo cal head set. Other

beltpack us ers, on that au dio chan nel, can hear the user as

nor mal. The but ton ac ti vates the nearby red LED as well

as the “TALK” LED, #6, when pressed.

3. Stage An nounce (SA) –When pressed, the user’s au dio is

routed to the stage an nounce con nec tor on the back of the

base sta tion. The user also loses their sidetone as an in di -

ca tion that stage an nounce is ac ti vated. The other wire less

beltpacks and wired us ers do not hear the user’s au dio.

The but ton is non-latching and ac tivates the nearby red

LED as well as the “TALK” LED, #6, when pressed.

4. Au dio Chan nel Se lect Button – Al lows user to se lect ei -

ther au dio chan nel A or B.

5. Bat/Overmod Light (BAT/OM) – Light will flash once

when unit is turned on if the bat tery is good. If the light

stays on, bat tery is low. If the light does not flash, bat tery

is dead. A nor mal mi cro phone gain set ting will cause the
