Telex BTR-300 Enabling Audio, Portable Transceivers, Intercom Switch, Auxiliary, Enable Switches

ENABLING AUDIO

PORTABLE TRANSCEIVERS

Select the TR-300 portables that will be used with the BTR-300. Push in the portable enable switches that correspond to the TR-300 remotes that you will be using. The numbers of the portable stations (1, 2, 3, and 4), are the last digit of the product number on the back of the TR-300. The Portable Transmit On light will illuminate when the remote on that fre- quency is turned on. The indicators may also light in response to outside interference on that channel or to intermodulation arising from portables being used at too close a dis- tance to the base. To prevent these sources from creating undesirable noise, all unused channels should be disabled.

INTERCOM SWITCH

The intercom switch in the front of the unit will act as an enabling switch when the unit is being used with either a Telex Audiocom wired intercom or Clearcom wired intercom.

When using a RTS system wired intercom the switch will act as a channel selector switch for selecting of either channel 1 or channel 2.

AUXILIARY

The AUX Switch on the front of the BTR-300 will enable any auxiliary audio input (or 4 wire intercom) that is supplied to the unit.
