TRANSMIT DELAY:
For either Quick Talk applications using a repeater system,
or for handheld receivers with longer turn-on delays, Quick
Talk provides for an adjustment of the delay before sending
transmit audio.
If the default delay is sufficient, you can skip this programming
step. However, if the attention-getting beep is being missed
because the repeater has not started transmitting, or because
a handheld radio takes too long to break squelch, you will
need to program a longer delay.
TO PROGRAM THE TRANSMIT DELAY:
a. Pick up the telephone receiver and listen for the acknowl-
edge tone.
b. Dial "96xxx", "xxx" being the selected code between 000
and 255. Refer to Table 11, below.
EXAMPLE: Dialing "96032"
* sets a one-second delay.
* NOTE: Inserting a zero in front of a two-digit number
(Example: "32"), completes the command.
Insert two zeros in front of a one-digit
number.
