Guided Tour - CR277 Front Panel
1: Antennas (Channels A and B)
- The antenna mountings allow full rotation for optimum
placement. In normal operation, both Antenna A (the antenna on the left) and Antenna
B (the antenna on the right) should be placed in a vertical position. Both antennas can be
folded inward for convenience when transporting the CR277. See the “Setting Up and Using
the Concert Series System” section on page 6 in this manual for information about antenna
installation and positioning.
2: RF (Radio Frequency) Level meter
- This “ladder” display (similar to the VU bar meter used
on audio devices) indicates the strength of the incoming radio signal. When the “100%” segment
is lit, the incoming RF signal is fully modulated and at optimum strength. When only the second
most left-most “10%” segment is lit, the incoming signal is at just 10% of optimum strength. If no
segments are lit, little or no signal is being received. See the “Setting Up and Using the Concert
Series System” section on page 6 in this manual for more information.
3: Volume (Channel B) / Power switch
- Use this to turn the CR277 power on and off. When
the receiver is on, the Power LED is lit. The control knob sets the level of the audio signal being
output through the Channel B output jack on the rear panel (see #2 on page 4 in this manual).
Reference level is obtained when the knob is turned fully clockwise (to its “10” setting).
4: Audio PEAK LED
- When the LED is lit, the signal is overloading and the HT7's input Level
adjustment must be attenuated. See the “Setting Up and the Concert Series System” section on
page 6 in this manual for more information.
5: Power LED
- When the receiver is on, the red Power LED will illuminate.
6: Volume control (Channel A)
- This knob sets the level of the audio signal being output
through the Channel A output jack on the rear panel (see #6 on page 4 in this manual).
Reference level is obtained when the knob is turned fully clockwise (to its “10” setting).
