2) Connect Power. For AC operation, connect the female end of the power cord to the AC input jack on the rear panel and plug the other end into a suitable electrical outlet (90-240 VAC, 50-60 Hz).

If external DC power is used, connect a power cord from the DC power source to the External Power Connector. (This cable will have to be fabricated.

3) Connect Antennas. You can use either two remote antennas or two whip antennas with 90-degree connectors to operate the UDR700; however, the operating range may be less with the whip antennas than with the remote antennas. When using remote antennas, for best performance place them at least three feet from each other and as high as possible with a direct line of

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.

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.

If the security level is set to “1” or “2”, the receiver must be powered on before the

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.

Note

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

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.

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.
