12-1307A01 w/o PTT; 12-1307A01 w/PTT;) can be purchased from GE

MDS. Handsets must have carbon microphone elements installed.

Dynamic microphones do not work with the module. (Handsets with a

push-to-talk (PTT) button are supported and recommended, as back-

ground noise can activate the VOX circuit and interrupt the payload

data.)

Operation

To operate the orderwire, activate the handset (PTT or VOX). This keys

the transmitter and passes the audio over the network to the handset of

the Master Station. Only one person can speak at a time (simplex). In

noisy locations, it might be necessary to cover the handset mouthpiece

to prevent accidental keying of the transmitter.

NOTE: When the transmitter is keyed by the orderwire operation,

normal payload data is interrupted.

Be sure to disconnect the module or handset to restore normal

data communications.
