TID(photo 1) provides simplex communication (alternate transmission of subscribers’ voice messages).
The acoustic signal from the subscriber, converted by the microphone into the electric one, is given to the amplifier and then to the loudspeaker of another subscriber.
The call and talk mode is provided by pressing the call and talk buttons of the TID unithousing. Structurally the TID unit is made in the form of the plastic tube, with the PCB with the microphone and the amplifier mounted inside.
One of the TIDunits is “master” (it can interrupt the message of the second one), another one is “slave” (it does not have this function).
The master unit has the redpower indicator at the end face, the slave unit power indicator is a green one.
Warranty period: 12 months.
Warranty storage period:6 months.
Average lifetime: not less than 10 years.
