If power to the transmitter is OFF or the RF level at the antennas is zero for some other reason (e.g.,
shadow effects), the red RF MUTE LED will be lit and the audio output will be muted.
If the antennas receive RF signal, the green RF OK LED will be lit, the RF bargraph will indicate the
field strength of the signal received by the active antenna, and the Diversity LEDs will indicate which
antenna is currently active.
The Audio bargraph indicates the audio level of the received signal. The red AF CLIP LED will flash to
indicate audio signal clipping.
2. After approximately 5 seconds, the display will change to the last active status screen before power-
ing down.
If you have assigned a NAME to the SR 450 receiver (see section 3.8.5), powering the receiver up will
cause the display to indicate the current frequency setting for 2 seconds and then change to the
assigned name.

In LOCK mode, the receiver receives the transmitter signal. The receiver is electronically locked so you
cannot make any adjustments. You may, however, call up the various status screens one after the other.
The "LOCK" label is shown on the display.
• Frequency: Carrier frequency in MHz.
• Name: Current receiver name (comes up only if you have previously named the receiver)
• Preset: Carrier frequency shown as Subchannel number within a Frequency Group
In SETUP mode, the electronic lock is disabled so you can adjust all receiver parameters. The "LOCK"
label is not shown.
The following setup screens are available:
- Auto Group Setup
- Auto Channel Setup
for selecting the receiving frequency*
- Preset
- Frequency in MHz
- Receiver name
- HT 450 handheld transmitter input gain (TX Gain)
- Infrared data transmission (IR)
- Rehearsal (RHSL)
- Extra (X-TRA)
If your system has only a single channel, we recommend using the Auto Group Setup screen (section
3.8.1) to set the frequency.
To set frequencies for a multichannel system, use the Auto Group Setup and Auto Channel Setup screens
(section 3.8.2).
