sec onds of the unit be ing turned off. Volt ages within the unit need to drop be low a thresh old be fore be ing re-pow ered. If powerd-up in less than 3 sec onds, the unit may boot as the wrong fre quency band. Even with the unit pow ered down via the power switch there are some cir cuits within the base that are en er gized. To com pletely re move power to the unit, the power cord must be dis con nected.

5. Por ta ble Sta tion Con nect – But tons used to en able or dis able the re spec tive re ceiver’s au dio. GREEN LED = Au dio en abled, LED OFF = Au dio dis abled.

6. 4-wire Se lec tion/Peak In put In di ca tors - Displays when 4-wire in ter coms are ac tive with a green in di ca tion. A red in di ca tion means the in ter com in put level is too high.

7. 2-Wire Se lec tion/Peak In put In di ca tors - Dis plays which 2-wire in ter coms are ac tive with a green in di ca tion. A red in di ca tion means the in ter com in put level is too high.

8. Aux il iary Se lec tion/Peak In put in di ca tor - Dis plays if aux il iary in put is 'ON" with a green in di ca tion. A red in di ca tion means the in ter com in put level is too high

9. Head set In ter com Se lect – Con trols the in ter com to which the lo cal head set is con nected. Each press of the but ton changes the con nec tion; chan nel 1, chan nel 2, both.

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 but ton.

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 but ton.

4. Au dio Chan nel Se lect Button – Al lows user to se lect ei ther au dio chan nel 1or 2.

5. Bat/Peak Light (BAT/PK) – 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 LED to flash for some of the words at nor mal speech lev els. If the gain is too high, the LED will be red dur ing all words at nor mal speech lev els.

6. Talk Light – LED is on when the talk but ton, SA or WTA is ac tive.

7. Talk but ton – Press to en able the au dio path from the lo cal head set mi cro phone. The “TALK” LED, #6, will turn red when en abled. A quick press and re lease latches the talk func tion, un less latch ing has been dis abled. Holding the but ton for over ½ a sec ond will cause the au dio path to be en abled only for as long as the but ton is held. If the talk func tion is latched on, press ing the talk but ton again will turn it off.

and con trols head set vol ume for in ter com chan nels “1” and “2”. Ei ther knob, “1” or “2”, turns the beltpack on. Both knobs must be off to turn the beltpack off. If only one knob is on, then that in ter com channel, “1” or “2” is on for both trans mit and re ceive au dio.

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 de fault set ting is soft ware selectable, as to which in ter com chan nels, “1”, “2”, “1 + 2”, or cur rently se lected chan nel, is ac ti vated along with the “WTA” but ton. The “WTA” but ton ac ti vates the nearby red LED as well as the soft ware se lected in ter com chan nels “TALK” LED if not al ready ac tive.

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 ti vates the nearby red LED.

4. Talk But ton - Press to en able the au dio path to ei ther in ter com chan nels “1”, “2” or “1 + 2”, from the lo cal head set mi cro phone. The as so ci ated “TALK” LED, #6, will turn red when en abled. A quick press and re lease latches the talk func tion, un less latch ing has been dis abled. Holding the but ton for over ½ sec ond will cause the au dio path to be en abled only for as long as the but ton is held. If the talk func tion is latched on, press ing the talk but ton again will turn it off.

5. Low Bat tery/Peak (BAT/PK) Light - 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 LED to flash for some words at nor mal speech lev els. If the gain is too high, the LED will be red dur ing all words at nor mal speech lev els.

NOTE: If your base sta tion is to be lo cated in a shielded rack mount en clo sure or other poor RF lo ca tion, you must re motely mount the 1/2-wave an ten nas with coax as sem blies. See "Ac -- ces sories and Re place ment Parts" sec tion for re mote mount ing hard ware.

Since RTS-TW car ries both chan nels of au dio on one ca ble, the four in ter com XLR con nec tors are con nected in par al lel when RTS is se lected. Thus any one of the four in ter com XLRs may be used for RTS in put. As shown in Fig ure 6-4, loop ing thru of the au dio may also be ac com plished via any of the rear panel XLRs when in RTS mode.
