To set these switches, the respective matrix diodes are either jumpered (1) or left open (0).
The functions of the switches in the initial setting diode matrix are summarized below (in alphabetical order).
This switch is used to specify the AF function.
Set the switch as indicated in the following table.
This switch is used to select the destination market (Europe/USA).
Set the switch as indicated in the following table.
These switches are used to specify the intermediate frequency in the AM band for the European market.
The setting of these switches is invalid when the USA market is selected (initial setting diode AMERICA = 1).
Set the switch as indicated in the following table.
This switch is used to specify the method used to detect a station during auto-tuning.
AM SD/IF specifies the method of detecting the AM band, while FM SD/IF specifies the method of detecting
the FM band.
Set these switches as indicated in the following table.
This switch is used to specify whether to output a beep whenever a key entry is accepted.
