Overview
Desk Top Telephones “ZONE 1”
DTT-50-Z and DTT-60-Z referred to as “ZONE 1” Desk Top telephones provide safe, reliable
communications in hazardous areas that are prone to high humidity, chemical vapors, dust and
physical abuse. Hands Free operation is standard on all models and the telephones can be
programmed for speed dialing. All models have the option of installing a supplemental receiver that
can be held against the ear opposite to the handset, in order to improve speech recognition in noisy
environments. In place of a Supplemental receiver a headset providing even greater flexibility can be
installed.
