AUDIO ALARM SIGNALS DURING OPERATION
(Training procedures to simulate detector audio signals)
The metal detector provides via the headset/loudspeaker a lot of information
to the operator. This short training chapter will allow the user to become
familiar with all of the different alarms and how they are distinctly different from
each other.
Of course, an audio alarm signal is produced only if the corresponding alarm
configuration has been selected (please refer to chapter 3.1).
4.1
Full Battery Charge Signal (Simulation)
- Insert 3 new unused batteries into the battery compartment.
- Switch the detector ON.
- For about the first 5 seconds after
the detector is switched ON, a fast
pulsed signal is audible.
4.2
Battery Charge Signal with 50 % of Capacity (Simulation)
- Insert 2 new unused batteries and 1 nearly empty battery into the battery
compartment.
- Switch the detector ON.
- For about the first 5 seconds after
the detector is switched ON, a slow
pulsed signal is audible. This signal
corresponds to a residual battery
capacity of 50 %.
The detection sensitivity remains constant while the battery voltage drops
down.
10 pulses/sec. with approx. 2300 Hz
6 pulses /sec. with approx. 2300 Hz
