1.5. Operation Modes

The NLJD ST 402 Cayman has the following modes of operation:
Primary operation mode: SEARCH
Secondary operation mode: AUDIO
Service mode: ADAPT
The main operation mode named SEARCH is meant for detecting nonlinear targets and
identifying them, based on the response levels as indicated by 16-segment bars.
The auxiliary operation mode named AUDIO allows demodulating the response and listening
to it through the built-in speaker or headphones. Use this mode upon detecting a response in the
SEARCH mode.
The ADAPT service mode is used to optimise the parameters in a given electromagnetic
environment and thus maximise the effectiveness of search. Engaging this mode is necessary
every time the device is switched on. It is advisable to pause during searches from time to time,
to repeat this procedure. During adaptation, the antenna must be pointed away from electronics
and large metal objects.
