Lead-In Tone
The Lead-In tone when programmed “rides” on the Lead-In
Delay, Hence, when transmitting a SELCALL ID a continu­
ous tone will be heard by the receiver in the duration of the
Lead-In Delay.
Lead-In Tone’s main purpose is to increase the probability
of contact between your unit and the other radio WHEN
TSQ SCANNING.
Normally on TSQ Scanning, if a carrier is detected and the
unit sees no SELCALL information on its first "glance” at the
particular signal, scanning resumes.
But if the Lead-In Tone is present, the unit waits further until
the SELCALL ID is received.
