LCD 1 Liquid Crystal Display shows battery status and frequency settings. (Use the Dual-channel Control Switch (6) to select frequencies for Receiver Channel 1 and Receiver Channel 2; in Hold position, only Receiver Channel 1 frequency appears in LCD.) Battery meter is only active when Dual-channel Control Switch is in the Hold position.

Antenna Input Jacks 2 BNC-type antenna connectors. Antennas A & B (split internally) both provide signals for Receiver Channel 1 and Receiver Channel 2. Attach the antennas to the antenna input jacks. Make certain that during operation there is a clear open-air path between the receiver antennas and the transmitters.

Diversity Indicators 3 for each antenna for each receiver

True Diversity operation: two antennas feed two completely independent RF sections on the same frequency for each receiver; automatic logic circuitry selects the superior signal.

Diversity Indicator 1 indicates which tuner has the better reception and is in operation for Receiver Channel 1; Diversity Indicator 2 indicates which tuner has the better reception and is in operation for Receiver Channel 2.

Power Switch

4

Turns the unit on and off.

with four positions:

 

 

External, Off, 1, Both

 

Choose “Ext”, if the unit is connected to an external power supply (12V DC source, 500 mA

 

 

nominal current, not included). In “Ext” position, both receiver channels and both outputs are

 

 

activated (indicated by illumination of Power/Peak LEDs 1 and 2).

 

 

Choose “Off” to turn the unit off.

 

 

Choose “1” to activate only a single receiver channel (Receiver Channel 1/Output A, indicated by the

 

 

illumination of Power/Peak LED 1). This conserves energy if you are only using one audio channel.

 

 

Choose “Both” to activate both receiver channels and both outputs (indicated by illumination of

 

 

Power/Peak LEDs 1 and 2).

 

 

Note: Selected receiver will be muted unless Dual-channel Control Switch (6) is in Hold position.

 

 

 

Power/Peak LED

5

Indicates which receiver channel(s) is (are) in operation. Also indicates receiver overload by

 

 

turning off; too much signal will cause blinking LED (off during peaks). To correct overload,

 

 

adjust audio gain on transmitter. (See Audio Input Level (Gain) Adjustments, page 13.)

 

 

 

Dual-channel Control Switch

6

This switch allows you to use the single LCD window to control each of the two receiver

with three positions: 1, Hold, 2

 

channels separately.

 

 

To set frequency for Receiver Channel 1, switch to 1 (left position).

 

 

To set frequency for Receiver Channel 2, switch to 2 (right position).

 

 

To lock settings and operate unit, switch to Hold (center position).

 

 

Note: Receiver Channel 1 is muted when switch is at 1; Receiver Channel 2 is muted

 

 

when switch is at 2; both channels un-mute when switch is at Hold.

 

 

 

Dual-channel Control LED

7

This LED is red when switch is in position 1, indicating muted operation for Receiver Channel 1.

 

 

It is also red when switch is in position 2, indicating muted operation for Receiver Channel 2.

 

 

LED turns green in Hold position, indicating unit is ready for operation.

 

 

 

Set

8

Use with the Dual-channel Control Switch and Up/Down arrows to choose operating frequencies

 

 

manually or automatically (using your choice of three automatic scan groups).

 

 

 

Up/Down Arrows

9

Press Up or Down arrows, in conjunction with the Set button, to choose operating frequencies

 

 

manually or automatically (using your choice of three automatic scan groups).
