4.1.1 Use of external hand-held antenna
A separate hand-held external antenna is available as an option for
use in special applications which require greater signal strength than is
possible to achieve with the transceiver's internal antenna.
When the external antenna is to be used, the following steps should
be followed:
a) Remove the protective cover from the external antenna connection
on the underside of the transceiver.
b) Fit and hand-tighten the external antenna to the connection point.
c) Turn on the transceiver and enable the external antenna from the
settings menu as described in section 5.4.2.
d) Make measurements, following the guidelines given in Section 4 of
this User's Manual. Note that the external antenna must be pointed
directly at the sensor´s in-built antenna in order to obtain the optimum
signal strength.
e) After completing the measurements, carefully unscrew the external
antenna and replace the protective cover on the transceiver.
f) In case the next measurements are to be made without the external
antenna, re-enable the internal antenna from the settings menu as
described in section 5.4.2.
Note! Difficulties in communication can occur if attempting to make
measurements with the external antenna enabled but not connected.
