Nowadays there is an increasing risk using handys or walky-talkies as a help for installing and maintaining lines and telephone systems. Especially in sensitive areas just like hospitals, EDP-Systems and open electronic controls because of possible electromagnetic interferences. That's why the use of handys and walky-talkies in the upper mentioned sensitive areas is meanwhile strictly forbidden.
The solution is: TALKSET
Linemen can use TALKSET for the installation and the maintaining of cable networks or communication systems as an intercom system by only connecting TALKSET with a live analog used telephone line. Two ore more technicians can communicate over such an analog telephone line. Having set the MON-mode on their TALKSET the linemen are able to listen into the line without any disturbance of signal transmission. One TALKSET being in TALK-mode occupies the line and voice signals can be received from another TALKSET being in MON-mode. If one technician wants to answer this message he only has to switch his TALKSET into TALK-mode. This is the way to build up an inhouse communication system – low cost and stable – from the basement up to the upper floors without producing any disturbing electromagnetic interferences.
