TO TRANSMIT A STORED PHONE NUMBER
DIALING IF THE PHONE NUMBER IS TO BE DISPLAYED
1) Press the
7
DTMF
button, and within 3 seconds,
2) Select 0-9 (stored phone number will be displayed).
3) Press PTT on the microphone.
4) The displayed phone number will be transmitted after
any delay as set by setup #9.
5) For a pause between digits, skip around dashes when
entering a phone number. For example, entering
9 - - 5551212 would add a pause between ‘9’ and ‘5’.
DIALING IF THE PHONE NUMBER IS NOT TO BE DISPLAYED
(This mode permits some measure of security against
casual viewing of the phone number. Although most
repeaters will require manual detection of the dial tone
following any required access tone dialing, the access
dial number could be recalled from a separate “phone
number” memory location and dialed. For this example,
the following procedure would “conceal” the number).
1) Press the
7
DTMF
button.
2) Press PTT on the microphone.
3) Select 0-9 (phone number, access number will NOT be
displayed)
4) The phone number will be transmitted.
Setup mode #9 sets the amount of transmit delay in
250 mSec. increments: 0 = NONE, 1 = 250 mSec.,
2 = 500 mSec., 3 = 750 mSec., 4 = 1000 mSec. The delay
allows the repeater sufficient time to stabilize following
the PTT action and before the first tone is actually
transmitted.
