4.1 GENERAL ANTENNA
The external antenna DC2041, which is delivered with all DECT-Com II main units, should normally be mounted on the main
unit together with a plastic ring (see 4.1.1 UNIT FUNCTION INDICATORS below).
4.1.1 UNIT FUNCTION INDICATORS
A package DC2048 with 3 differently coloured plastic rings is enclosed in the box of each DECT-Com II main unit. The rings
are meant to seal around the antenna connector, but also to indicate the function of the unit; for instance a red ring for a
base unit, a green ring for a portable unit and a black ring for an “other” unit.
4.2 OMNI DIRECTIONAL VEHICLE ANTENNA
The omni directional antenna DC2046, with magnetic foot, can replace the external antenna DC2041,for instance to
improve communication with portable units outside of a vehicle if the base unit is placed inside.
Notice: No other external antennas than DC2041 or DC2046 are allowed for use with the DECT-Com II system.
