Страница: 13 / 36

Encrypted Digital Wireless System
To toggle between BUTTONS ENABLED and BUT­
TONS DISABLED, press and hold the SELECT Up
button while setting the POWER switch to On.
Menu Interface
The menu interface consists of six linked menus:
Main Tuning
TV Tuning
Group Tuning
AES Output
Security
Key Generation
The MENU Button is used to cycle through the menus.
The menus are:
Main Tuning Menu
The Main Tuning menu is normally the first screen that
appears on the Information and Status Display after the
power up sequence is complete. This screen shows the
frequency (in MHz) that the UDR700 is tuned to, the
transmitter battery voltage (if actively receiving this
information from the transmitter) and the Frequency
Select Switch settings for the transmitter.
6 6 8 . 1 0 0 8 . 7 V 1 9
If the transmitter battery is low, the voltage display will
blink. If the transmitter battery is very low, a “Battery
Low” warning message will flash periodically, regardless
of what menu is currently being displayed.
The UDR700 comes preloaded with three groups of
seven selected intermod-free frequencies. In the Main
Tuning menu, the SELECT Up and Down buttons can
be used to navigate among the seven frequencies in
the current group. (See Group Tuning Menu.)
You can also tune the receiver across the 25.5 MHz
block in 100 kHz increments by pressing the SELECT
Up or Down button while pressing and holding the
MENU button. Holding either SELECT button down
activates an autorepeat function for faster tuning.
If pressing any button results in “BUTTONS DISABLED”
being displayed, the front panel buttons have been
disabled. (See ENABLING AND DISABLING THE
BUTTONS.)
TV Tuning Menu
The TV Tuning menu is just like the Main Tuning menu,
except that the applicable UHF TV channel number is
shown in the center of the display in place of the
transmitter battery voltage. This makes it easier to
avoid occupied UHF TV channels in the geographical
area of operation.

Group Tuning Menu
The Group Tuning menu displays the current group (the
three groups are designated A, B, and C) and the
selected frequency within that group. The Transmitter
Frequency Select Switch settings are shown at right, as
on the other tuning menus.

In the Group Tuning menu, the SELECT Up and Down
buttons navigate among the seven frequencies in the
current group. To choose a different group, press either
SELECT Up or Down while holding down the MENU
button.
Note: If one of the tuning menus is active when
the receiver is powered down, the receiver will
return to that same menu following the three boot
messages the next time it is turned on.
AES Output Menu
The AES Output menu allows toggling the DIGITAL
AUDIO OUTPUT (AES-3id jack at the receiver’s back
panel) on or off. Use the SELECT Up and Down
buttons to change the setting.
Caution: To minimize the chance that the digital
audio output signal will radiate unwanted RF
energy, this function should be turned off
unless the digital audio output is in use.
Security Menu
The Security menu displays the current security level.
(See The 700 Series Encryption System.)

This menu also allows decryption in the receiver to be
temporarily turned off. Use the SELECT Up and Down
buttons to toggle between decryption on and off. If the
UDR700 is turned off with decryption disabled,
decryption will automatically be enabled when the unit
is powered up again.
Note: The only reason to turn decryption off is to
hear what the received audio sounds like without
the right decryption key. 700 Series transmitters
are incapable of transmitting an unencrypted
signal.
Key Generation Menu
The Key Generation menu is the entry to the security
key generation process.
