Lectrosonics UDR700, Инструкция по эксплуатации

Страница: 22 / 36

UDR700 / UM700 / UT700
Note: The -40 setting is approximately equal to 10
mV, the 0 position will give 0.775 VRMS, and the
+15 setting will allow up to 4.4 VRMS when the
transmitter is fully modulated. The correct setting
will depend on the requirements of your sound or
recording system.
22) If necessary, perform a walk test to map the effec­
tive operating range for the transmitter(s) prior to
the beginning of the function.
Note: In Security Level 2, if you wander out of
range for more than 10 seconds, the transmitter
must be turned off, then on again to resynchronize
with the receiver. In Security Level 3, if you
wander out of range for more than 10 seconds, a
new encryption key will have to be generated for
the system to operate.
Changing the Security Level
1) Determine the new security level. (See The 700
Series Encryption System.)
2) Press and hold the SELECT Down button while
powering up the receiver. The display will show the
current security level. (Default is Level 1.)
3) Use the SELECT Up or Down buttons to choose a
new security level, then press the MENU button to
finalize the security level selection process. The
Information and Status Display will then display a
message indicating the level of security (Level 1, 2
or 3). Pressing the MENU button again enters the
key generation process.
Note: Changing security levels requires that a new
key be sent to the transmitter(s) before the system
will operate.

Setting the Encryption Key
Note: In Security Levels 1 and 2, any number of
transmitters can receive the same encryption key.
In Security Level 3, only one transmitter may
receive the encryption key. (See The 700 Series
Encryption System.)
1) To set a new encryption key, press the MENU
button to scroll through the menus until the SECU­
RITY MENU is displayed in the Information and
Status Display. Press MENU once more to enter
the Key Generation Menu. “MAKE NEW KEY?” will
be displayed in the Information and Status Display
with an “Up” arrow to the message’s right.
2) Press the SELECT Up button to create a new
encryption key (or press MENU to cancel creating a
new key and return to the MAIN TUNING MENU
display). Follow the directions on the Information
and Status Display until the prompt “NEW KEY TO
TX ^” is displayed.
3) Connect the appropriate Key Cable between the
transmitter and the UDR700, then turn on the
transmitter.
Note: Each transmitter uses a different Key Cable.
(See Encryption Key Cables.)
4) Press the SELECT Up button on the UDR700 to
send the encryption key to the transmitter. Depend­
ing on the transmitter, the Power LED on the UT700
or the two Modulation LEDs on the UM700 blink to
confirm receipt of the new key.
Level 1: 1 blink
Level 2: 2 blinks
Level 3: 3 blinks
Note : In Security Levels 1 and 2, you may program
as many transmitters as you like to match the
receiver. Repeat steps 3 and 4 for each
transmitter. This will transmit the same encryption
key to each transmitter; however, once you leave
this prompt, this particular encryption key can
never again be sent out of the Security jack to a
transmitter. A new encryption key will have to be
created. In Security Level 3, each encryption key
may be sent to only one transmitter.
