The side tone adjustment feature is conveniently controlled in the field from the dip switch settings on the amplifier module. The Model 1192 provides the standard setting and a high noise setting for busy roadside installations or noisy environments. The side tone adjustment feature optimizes call quality for your payphone leading to increased usage and higher revenue. Criminals commonly employ the use of payphones and pagers as a way of communicating to conduct illegal activities. The combination of payphones and pagers provides criminals with an untraceable communication network to operate their illegal transactions or acts.
Criminals tend to repeatedly use the same payphone stations to operate their illegal businesses.
These payphones and enclosures experience a dramatic increase in vandalism which costs the station owner money. Criminals spend hours at your payphone receiving incoming calls which prevents legitimate revenue producing calls. The Model 892 is a line powered device which is conveniently field installable and mounts in the upper housing of the payphone. When installed, the TEK Model 892 is active for the entire duration of every call. After a user dials a phone number, there is a momentary loss of talk power.
