 Tones

 

 

The user has 9 sound profiles in the Motion channel from which to choose. They are 

divided into three groups: Coins: (1, 2, 3); Relics: (1, 2, 3); User: (1, 2, 3).

NOTE: We strongly recommend using one of the Coins profiles to search for coins and other 
small objects made of non-ferrous metals.   

Coins and 
Relics profiles

Factory set profiles, which cannot be edited by the user (although they 
may be previewed – by pressing a button)

User profiles

These allow for sound personalization and can be edited – any tone 
between the range of 60 to 999 Hz can be assigned to one of the 120 
identification points

After selecting a suitable sound profile from the User group it can be edited by pressing 

the      button. The                   buttons are used to choose the ID number for which a specific 
tone is applied and the                  buttons are used to change the frequency of the sound. 
The ID number currently edited is shown by a digit and a cursor (a filled triangle for the Copy 
mode and an empty one for the Normal mode) which are shown at the bottom of the display.

The tone editing screen can be displayed in two modes – the Normal mode and the Copy

mode. Choosing a mode is done by pressing

 

the         button. Changing the cursor’s position 

(a filled triangle) in the Copy mode results in copying the tone value from an adjacent ID 
position, the one the cursor was previously on. In this way it is possible to quickly set the same 
tone to a whole group of ID numbers.

In the Normal mode changing the cursor’s position (an empty triangle) does not copy the 

value of an adjacent ID position. In this way it is possible to set a sound tone individually for 
each ID number and, if needed, listen to the whole sound profile. Changes are saved after 
switching off the detector’s power supply.

 Wireless

 

Alter71 has a built-in wireless digital data transmitter which can work on one of two 

available radio frequencies. The design of the digital connection was made especially for our 
detectors – therefore there is no lag or background noise. The use of the accompanying 
wireless devices is detailed in their respective user’s manuals.

Off

The transmitter is off, the built-in speaker and headphone’s socket are active

Ch 1, Ch 2

The transmitter is on, the detector’s sound generating circuit is off
