H707 - 1 Tone Singletone via PTT Button
When selecting this option a pop-up window is displayed and you are asked to enter a frequency
for single tone1. If H707 is enabled, RAT1 and RAT2 buttons are disabled and single tone1 is
sent out through PTT on all channels. This option is incompatible with all the MDC Unit ID (PTT)
options. The valid range for single tone1 is from 300 Hz to 3000 Hz in increments of 1 Hz. This
option is incompatible with the following options:
Singletones - General (PTT/RATs)
H742 - 2 Tone Singletone via RAT Buttons.
All the MDC Unit ID (PTT) Options.
The following options are enabled if you select this option :
Singletone Non-Std. Pretime
Singletone Time Duration
H619 -Omit MDC Side Tones
H742 - Up to 2 Singletones via RAT Buttons
This option is very similar to the Singletone - General option. When selecting this option two
pop-up windows are displayed on the screen sequentially. Enter a frequency in both the
windows. If this option is enabled and none of the MDC Unit ID options are selected then
signalling on PTT is disabled. If this option is selected along with any of the MDC Unit ID options
then MDC Unit ID is sent out via PTT. Single tone1 is sent out through RAT1 and single tone2 is
sent out through RAT2. You may leave the default single tone 2 frequency, in case you need
only one single tone.This option is incompatible with the following options:
Singletone - General (PTT/RATs)
H707 - 1 Tone Single tone via PTT Button

Multiple Repeater Access Codes - MDC 1200
The following options are enabled if you select this option :

Singletone Non-Std. Pretime
To select this option you must select either Singletones - General or H707 or H742. When
selecting this option a pop-up window will be displayed on the screen and you will be asked to
enter a pretime value. Pretime is the time for which the unmodulated carrier goes out before
sending the signal out to bring up the repeater. The valid range is from 0 to 1000 ms in
increments of 10 ms. The default value is set to 40 ms.
Singletone Time Duration
To select this option you must select Singletones - General or H707 or H742. When selecting this
option a pop-up window will be displayed on the screen and you will be asked to enter a time
duration value. The valid range is 0 to 20,000 ms in increments of 10 ms. If option H707 is
selected, the valid range for single tone time duration is from 1 to 20,000 ms in increments of 10
ms. When "0" is entered as single tone time duration, the process of transmitting single tones
becomes manual. In manual process you must press PTT for the period of time you want to
transmit the singletones. The manual timing and H707 are incompatible. The default value for
the time duration is 600 ms, if this option is not selected.
