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.
