3.3 Dip Switch Settings
Table 4 describes the functions provided by the dip switch on the bottom of the unit. The factory setting are
underlined.
3.4 Setting Levels
Receive audio is controlled via the front panel volume control. Handset audio for the LE10 is set via R28 on
the circuit board. It is factory set at mid range.
The transmit audio level is set via R44 on the circuit board. It should be set to provide the appropriate deviation
on the radio.
