System Op er a tionFre quency Plan Over viewThe BTR/TR-8XX has 36 fac tory de fined fre quency groupsand 12 user-programmable fre quency groups. A Group de --fines the two base sta tion trans mit fre quen cies and thus thetwo re ceive fre quen cies on all the beltpacks. A Chan nel de --fines a base sta tion re ceive fre quency and thus a beltpacktrans mit frequency. A base sta tion re ceive chan nel that doesnot have a fre quency set for it will have a dash to the right ofit on the Group/Chan nel se lect screen. De tails on set ting fre --quen cies may be found in the “BTR-800 Menu Struc ture” and“TR-8XX Menu Struc ture” in struc tions in this sec tion. Fac tory-Defined GroupsThe 36 fac tory-defined groups were care fully cho sen to avoidcer tain intermod prod ucts and var i ous other pos si ble sourcesof in ter fer ence. The Groups are set and can not be changed. There is a lim ited num ber of chan nels which can be chosenfrom within these groups.The first 24 factory-defined groups (01A – 12B) are “pair”groups that can be used for sin gle (up to 4 beltpacks) and dual(up to 8 beltpacks) BTR-800 sys tems. They are ar ranged01A, 01B, 02A, 02B…011B, 012A, 012B. A “pair” group,like 1A and 1B, have dif fer ent base sta tion transmit fre quen --cies, how ever, they both have the same eight base station re --ceive chan nels from which to choose. Each chan nel rep re sents a unique fre quency. For ex am ple, one BTR-800 could be seton Group 02A and chan nels 01, 02, 03 and 04. The otherBTR-800 could be set on Group 02B chan nels 05, 06, 07 and08. As long as the chan nels are dif fer ent, everything shouldbe fine.The next 12 groups (13 – 24) are sin gle groups that primarilyare used for sin gle (up to 4 beltpacks) BTR-800 sys tems. Thenum ber of chan nels from which to choose from in thesegroups will vary from group to group.User-Programmable GroupsThe 12 user-programmable groups are ini tially empty. Thetrans mit and re ceive fre quen cies are fully editable within these groups. In fact, fac tory-defined groups may be cop ied touser-programmable groups and then ed ited if de sired. See the“BTR-800 Menu Struc ture” and “TR-8XX Menu Struc ture”in struc tions in this sec tion for de tails on how to copy and editfre quen cies.

When com pleted the user should have abase sta tion and 1 to 4 beltpacks up and run ning with full op er --a tional abil ity. The base sta tion will be on Group 01A with itsfour re ceiv ers on chan nels 01, 02, 03 and 04. Each beltpackwill be on Group 01A with a unique trans mit chan nel num bermatch ing one of the base sta tion re ceive chan nels. 1. Plug-in the base sta tion via the sup plied power cord andcon nect the an ten nas. The color dots on the base shouldmatch the color rings on the an ten nas.2.

Check that frontpanel IC A and B is in 2-wire for AudioCom (Telex), RTS-TW and ClearCom wired sys tems, and 4-wire for RTSMa trix and stand-alone op er a tion. 6. Place bat ter ies in the beltpacks.7. Re move the rear switch cover on the beltpacks. Set thebeltpack rear panel slide switch to push-to-talk (PTTALK).8. Press [MENU] as pow er ing-up each beltpack. This willplace the beltpack on group 01A with the chan nel 01flash ing.9. Use the [UP] and [DOWN] ar row but tons to change thechan nel to match a channel on the base sta tion. Then press [SET]. If leav ing on chan nel, just press [MENU]. Eachbeltpack should have a unique chan nel num ber. 10.

Theymay be too low or too high. Check to make sure you arestill well within range of the base station.LOW OUTPUT - System produces a low output level. Check the gain setting on both the beltpacks and the base.They may be too low.FEEDBACK - Moving around area of use produces“squeal” or “howl” in various locations using ext.speakers.Reduce the gain settings on both the beltpacks and thebase. They may be too high.DROPOUTS - When moving around the area of use there seems to be locations where the signal “swooshes” orcompletely disappears.Make sure both antennas on the base and beltpack areconnected and follow the location suggestions. Change the location of the base unit and antennas or avoid the badareas with the remote beltpacks. INTERFERENCE - System picks up signals other thanwireless intercoms.Make sure that all the Telex beltpack(s) are on. If there are any unused receivers at the base, turn the audio off fromthose receivers by deselecting the appropriate “PortableStation Connect” button.If problems persist with the beltpack on, you will probably need to change the group. Make sure the base andbeltpack match after any Group/Channel change.NO AUDIO from BASE or BELTPACK headsets.Check Transmitter switch on base and beltpack. Checktalk LED to make sure it is on. Make sure beltpackbatteries are OK.

Tech TipsFre quency In ter ac tionUn for tu nately, ra dio fre quency (RF) chan nels can not be ran --domly se lected for use in ra dio de vices. They must be se lected to avoid known fre quen cies in use, FCC re stric tions on the lo --ca tion of de vices, and even in ter fer ence be tween your own RF de vices.

Mi cro phone Gain Ad just mentThe mi cro phone gain con trols on the base sta tion and beltpack are set to mid-levels by the fac tory. In most cases this set tingwill work fine and only on loud speech will theovermodulation (OM) in di ca tor light. How ever, in en vi ron --ments where the back ground noise is loud or the user has astrong/quiet voice, the gain con trol will need to be ad justed. In Fig ure 33 the gain is set cor rectly. The user’s root-mean-square (RMS) sound level is well be low the OM thresh old and onlyon peaks does his or her voice flash the OM in di ca tor light. Fig ure 34 dis plays the same gain set ting as in Fig ure 33 butbrought into a high noise en vi ron ment. The user’s voice nowlights the OM in di ca tor all the time he or she speaks due to the higher noise plus the user speak ing louder. The re sult on thesys tem is dis tor tion on louder speech. The mi cro phone gainmust be re duced. The same ap plies to a user with a pow er fulvoice. If some one sets the sys tem mic gain to their voice anduser has a much stron ger voice, then the gain will need to bere duced, even if the back ground noise is the same.Al ways re mem ber to set the mi cro phone gain based on the sit --u a tion and lo ca tion in which the equip ment will be used. If the equip ment is used on the field dur ing a foot ball game, set thegain based upon a loud sta dium, NOT the quiet sta dium 2hours be fore a game. If a pro duc tion stu dio user has a quietvoice, set the gain to their voice and NOT the stage hand’sloud voice who helped set up the sys tem.10-1OM THRESHOLDUSER'S VOICENOISESOUND LEVEL, RMSOM THRESHOLDUSER'S VOICENOISESOUND LEVEL, RMS Fig ure 33Low Noise En vi ron mentMi cro phone Gain Set Cor rectlyFig ure 34High Noise En vi ron mentMi cro phone Gain Set Too HighSection10
