The dis tance be tween the base sta tion’s re ceive and trans mit an ten nas is not ad just able when the an ten nas are con nected di -- rectly on the back of the unit.

The an ten nas can be remoted for better sig nal path. A Telex coax as sem bly with re mote an ten nas may be re quired. See “Ac ces sory” sec tion for or der ing in for ma tion.

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 mote the 1/2-wave an ten nas with coax as sem blies. See “Ac ces sories and Re place ment Parts” sec tion for remote mount ing hard -- ware.

Base Sta tion - Rear Panel

Lo ca tion

Lo cate the base sta tion with the front and rear of the unit ac -- ces si ble so that switches may be set and con nec tions made. Place the transmit and re ceive an ten nas on the base sta tion. Make sure the an tenna’s color band match the color dot near each an tenna. See “An tenna In for ma tion” sec tion for more in -- for ma tion on choos ing a proper op er at ing lo ca tion.

Power Con nec tion

Plug the sup plied power cord into the unit. The base sta tion has an IEC power re cep ta cle that ac cepts 100 – 240VAC, 50 – 60Hz. The spe cific re cep ta cle type is an IEC 60320/C14. The cord it ac -- cepts is an IEC 60320/C13. These cords are com mon and avail -- able through many re tail hard ware/elec tronic stores if the cord is lost.

Trans mit Switches

There are two switches lo cated on the lower left side of the rear panel. The up per switch sets the trans mit power lev el to high or nor mal. The lower switch turns the trans mit ter on or off.

Trans mit Power

Set the power level to nor mal if us ing the beltpacks at close to me dium dis tances (<200 feet, 161m, line-of-sight) from the base sta tion. Set the power level to high if us ing the beltpacks at a dis tance (>200 feet, 161m, line-of-sight) from the base sta tion.

On/Off

Set the trans mit ter switch to on for nor mal use. In the off po si tion the base station transmitter is dis abled. Set ting the switch to off will dis ables all the beltpacks from hear -- ing any one else or even their own sidetone.

A Group de -- fines the base sta tion trans mit fre quen cy and thus the re ceive fre quen cy on all the beltpacks. A Chan nel de fines a base sta -- tion re ceive fre quency and thus a beltpack trans mit frequency. A base sta tion re ceive chan nel that does not have a fre quency set for it will have a dash to the right of it on the Group/Chan -- nel se lect screen. De tails on set ting fre quen cies may be found in the “BTR-700 Menu Struc ture” and “TR-700 Menu Struc -- ture” in struc tions in this sec tion.

Fac tory-Defined Groups

The 36 fac tory-defined groups were care fully cho sen to avoid cer tain intermod prod ucts and var i ous other pos si ble sources of 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 chosen from within these groups.

System Op er a tion

Sys tem Quick Start

Fol low the list be low to quickly get a base sta tion and beltpack(s) op er at ing. When com pleted the user should have a base 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 its four re ceiv ers on chan nels 01, 02, 03 and 04. Each beltpack will be on Group 01A with a unique trans mit chan nel num ber match ing one of the base sta tion re ceive chan nels.

1. Plug-in the base sta tion via the sup plied power cord and con nect the an ten nas. The color dots on the base should match the color rings on the an ten nas.

2. Base sta tion rear panel switches: Trans mit power set to High and on.

3. En sure base sta tion rear panel IC switch matches at tached wired in ter com sys tem. If used stand alone or con nected to a 4-wire sys tem then IC switch po si tion is Not Ap pli ca ble.

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-700 sys tems. They are ar ranged 01A, 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-700 could be set on Group 02A and chan nels 01, 02, 03 and 04. The other BTR-700 could be set on Group 02B chan nels 05, 06, 07 and

08. As long as the chan nels are dif fer ent, everything should be fine.

The next 12 groups (13 – 24) are sin gle groups that primarily are used for sin gle (up to 4 beltpacks) BTR-700 sys tems. The num ber of chan nels from which to choose from in these groups will vary from group to group.

User-Programmable Groups

The 12 user-programmable groups are ini tially empty. The trans mit and re ceive fre quen cies are fully editable within these groups. In fact, fac tory-defined groups may be cop ied to user-programmable groups and then ed ited if de sired. See the “BTR-700 Menu Struc ture” and “TR-700 Menu Struc ture” in -- struc tions in this sec tion for de tails on how to copy and edit fre quen cies.

4. Press [MENU] as pow er ing-up the base sta tion. This will place it on group 01A and set the re ceives on chan nels: 01, 02, 03, and 04.

5. Place the front panel IC “IN” and “OUT” level con trols in the 12:00 o’clock po si tion. Check that front panel IC is in 2-wire for AudioCom (Telex), RTS - TW and Clear-Com® wired sys tems, and 4-wire for RTS Ma 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 the

beltpack rear panel slide switch to push-to-talk (PT TALK).

8. Press [MENU] as pow er ing-up each beltpack. This will place the beltpack on group 01A with the chan nel 01 flash ing.

9. Use the [UP] and [DOWN] ar row but tons to change the chan nel to match a channel on the base sta tion. Then press [SET]. If leav ing on chan nel, just press [MENU]. Each beltpack should have a unique chan nel num ber.

10. The group/chan nel on the beltpack should now match the group and a re ceive chan nel on the base sta tion. Noth ing should be flash ing on the beltpack screens.

11. Plug head sets into the beltpacks and set the mi cro phone gain so the BAT/OM LED will flash at the be gin ning of most words at nor mal speech lev els.

Set mi cro phone gain in both the beltpack(s) and the

❒ ❒

base sta tion.

The base sta tion and beltpack(s) are on the same group and the beltpack(s) are on their own unique transmit chan nels that match the base sta tion re ceive chan nels

Check that the talk but ton is en gaged. The talk LED will be il lu mi nated.

Trou ble shooting

Re read the sec tions of this manual to make sure you have com pleted sys tem set-up prop erly.

PROBLEM SOLUTION

DISTORTION - System’s audio quality seems distorted

at medium to high input levels.

HISS - System seems to produce a “hiss” which is undesirable.

LOW OUTPUT - System produces a low output level.

FEEDBACK - Moving around area of use produces

“squeal” or “howl” in various locations using ext. speakers.

DROPOUTS - When moving around the area of use there seems to be locations where the signal “swooshes” or completely disappears.

If you are un able to solve the prob lem, con tact the dealer from whom you purchased the sys tem for as sis tance.

Reduce microphone gain by adjusting microphone gain control.

Check the gain setting on all beltpacks and the base. They may be too low or too high. Check to make sure you are still well within range of the base station

Check the gain setting on both the beltpacks and the base. They may be too low.

Reduce the gain settings on both the beltpacks and the base. They may be too high.

Make sure both antennas on the base and beltpack are connected and follow the location suggestions. Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks.

INTERFERENCE - System picks up signals other than wireless intercoms.

NO AUDIO from BASE or BELTPACK headsets.

Make sure that all the Telex beltpack(s) are on. If there are any unused receivers at the base, turn the audio off from those receivers by deselecting the appropriate “Portable Station Connect” button.

If problems persist with the beltpack on, you will probably need to change the group. Make sure the base and beltpack match after any Group/Channel change.

Check Transmitter switch on base and beltpack. Check talk LED to make sure is is on. Make sure beltpack batteries are OK.

Fig ure 23 dis plays the same gain set ting as in Fig ure 22 but brought into a high noise en vi ron ment. The user’s voice now lights 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 the sys tem is dis tor tion on louder speech. The mi cro phone gain must be re duced. The same ap plies to a user with a pow er ful voice. If some one sets the sys tem mic gain to their voice and user has a much stron ger voice, then the gain will need to be re 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 the gain based upon a loud sta dium, NOT the quiet sta dium 2 hours be fore a game. If a pro duc tion stu dio user has a quiet voice, set the gain to their voice and NOT the stage hand’s loud voice who helped set up the sys tem.
