1. General
Description
Model
HDX*2 field telephone set is the wire communication audio terminal
in the field and indoor conditions.
It
adopts advanced electronic technology and design which has low
power consumption ,clear
voice and long communication distance
performance.It is can be used not only as the
magnet telephone but also as the normal telephone that is connected
into the wire common telephone network.
It adopts the sealed
structure andaluminium
alloycompression casting
which has great
water-proof performance. It has the advantages of compact
structure, beautiful and dignified, solid and durable, fall-proof,
dash-proof and water-proof performances.
