3 Setting Up
3.6 Powering Up
3.7 LOCK Mode
Note:
1. Press the front panel POWER switch to switch power to the receiver ON.
Pressing POWER automatically places the receiver in Lock mode, and the display will indicate the cur-
rently active frequency in MHz and the "LOCK" label:
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 "MUTE" label will appear on the display and the audio output will be muted.
If the antennas receive RF signal, the bargraph meter below "A" and "B" indicates the field strength
of the signal received by the active antenna.
The bargraph below "AUDIO" indicates the audio level. "CLIP" illuminates to indicate audio signal clipping.
2. After approximately 5 seconds, the display will change to the last active status screen before power-
ing down.
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.
To enter Lock mode, either switch power to the receiver ON or (if the receiver is ON and the "LOCK" label
is not displayed) press and hold the SETUP control until the "LOCK" label appears.
Approximately 15 seconds after the frequency in MHz has appeared, the display will change to the last
active status screen before powering down.
The following status screens are stored in memory on powering down and displayed after powering up:
Preset, Frequency, Name.
To scroll through the following status screens, turn the SETUP control CW or CCW:
• Preset (comes up only if a Preset has been saved): Carrier frequency shown as Subchannel number
within a Frequency Group
• Frequency: Carrier frequency in MHz. (This screen is always available, even if no Preset has been
saved.)
• Name: Current receiver name (comes up only if you have previously named the receiver)
• Battery: Transmitter battery capacity in hours. (This screen will not be saved on powering down.) The
way the capacity is indicated depends on the remaining battery life:
- More than 10 hours:
- Less than 10 hours:
