Operating instructions

11
The audio signal comes straight from the R1 receiver circuit. It allows the operator to listen
to the true signal level and can allow the experienced user to ‘understand’ signals better. It
does have the disadvantage that smaller, deeper objects give fainter signals.
DIGITAL
The audio signal is directly controlled by the R1 computer. In this mode the audio signal is
either on or off. This means that a deep object will give the same audio volume as a shallow
object. This can make the initial location of an object easier and more positive but does not
convey any other information.

These functions allow the operator to store and recall the set up of the R1. Up to two
programs can be stored. A program will store all of the current settings including
Discrimination, Sensitivity, Frequencies etc. It will not store the Display Contrast and
Brightness settings. These are stored separately and retrieved automatically at turn on.
Once Store or Recall is selected rotate the MENU/SCROLL control to highlight the Program
to be stored or recalled and then press the ENTER button. The R1 comes with the first three
programs preset to commonly used settings. The COIN INLAND Program is set for high
sensitivity to precious metals, the ALL METAL Program for deep seeking of all metals and
COIN BEACH Program for Beach use.

setting may be required.
