1750-HZ TONE BURST FOR EU REPEATERS: Set PITCH to 1750. This adds an 0.5-second tone burst at start of any transmission. You can also hold PITCH indefinitely anytime after starting a transmission. This applies even if the receiver was unsquelched, or if PL TONE was set to OFF, as long as the selected tone is 1750 Hz.
PL TONE DEVIATION RANGE ADJUSTED FOR 1750-HZ TONE: The range in this case is 0.7-3.0 kHz, with a default of 1.8. To adjust PL tone deviation for the 1750-Hz tone, first select 1750 Hz using the PITCH control, then locate the FM DEV menu entry and tap 1 (PRE) to change the menu entry name to PL DEV. Adjust the parameter as required.
