In Security Levels 1 and 2, you may program as many transmitters as you like to match the
receiver. Repeat steps 9 and 10i for each transmitter. This will transmit the same encryption Modulation LEDs
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.

connector.
11) Set Transmitter Gain - Depending on the unit, position the
microphone in the location where it will be used. While
speaking or singing at the same voice level that will be used
during the actual program, observe the Modulation LEDs on
the UM700 and the UT700. Adjust the Audio Level Control
until the -20 LED occassionally blinks red and the -10 LED
glows green.

Note
The transmitter Audio Level Control should not be used to control the volume of your sound
system or recorder levels. This gain adjustment matches the transmitter gain with the user’s
voice level and microphone positioning. Different voices usually require different settings of
the Audio Level Control. Check this adjustment as each new person uses the system, or
adjust it for the loudest voice. Also, the UDR700 receiver needs at least 5 uV of RF signal to
begin operating - this is the approximate squelch threshold. Between 5 uV and 10 uV,
reception will be marginal and brief gaps in the audio may occur if the receiver squelches.
Check to see that at least the lowest four RF LEVEL LEDs stay lit when the transmitter is
turned on.
12) Set System Audio Levels. Set the UDR700 rear panel

wireless system and adjust the receiver analog audio output

may hear steady noise

Note
If the security level is set to “1” or “2”, the receiver must be powered on before the
transmitter. If the security level is set to “3”, communications do not begin until a fresh key
is transferred.
13) Perform and Walk Test. Perform a walk test of the wireless
microphone system prior to the actual event. Keep in mind
that the security level has a direct impact on system
operation. (See 700 Series Operations Manual, The 700
Series Encryption System) Mark, or otherwise note, the
maximum range of the receiver in order to minimize
performance problems.
PROTECT THE ENCRYPTION KEY
The encryption key is never displayed and once a key transfer session is
complete, the existing key can never again be transferred out the receiver’s
security port. However, the key is stored inside the transmitter and the
receiver, so you should treat the equipment as you would a key, storing it in a
safe place for as long as the key is important.
For maximum security, it is recommended that you set a new key often,
ideally before and after each use of the system, and that you always store the
equipment in a physically secure location.
Note that in Security Level 3, the equipment itself enforces the most
important part of this policy, namely that no key shall ever be used more than
once.
