• The last item in the result list is followed (the first item preceded) by the "EXIT" option.
The display indicates the setting cur-
rently in memory, e.g., "-90 dB". Use
and to select one of the following set-
tings: -80, -85, -90, -92, -94, -96, -98,
-100 dB.
Never set the squelch threshold any
higher than absolutely necessary. The
higher the squelch threshold, the lower
the sensitivity of the receiver and thus
the usable range between transmitter
and receiver.
1. Be sure to assign a separate carrier frequency to each wireless channel (transmitter and receiver).
2. To find intermodulation-free carrier frequencies quickly and easily, we recommend using Auto Preset
to select all required carrier frequencies from the same Frequency Group within the same Preset.
If reception on the selected carrier frequency is poor, use Auto Channel Setup (refer to section 3.9.2)
to find the next clean Subchannel within the selected Frequency Group. Should you find no clean
Subchannel, use Auto Group Setup to select a different Frequency Group within the same Preset and
select a new frequency for each WMS 400 channel (refer to sections 3.9.1 and 3.9.2).
3. Do not operate two or more wireless channels on the same frequency at the same time and location.
This would cause unwanted noise due to radio interference.
To toggle between LOCK and SETUP modes, press and hold the key for about 1.5 seconds.
When the receiver is in LOCK mode, the "LOCK" label is shown on the display. In SETUP mode, the
"LOCK" label is not shown.
Use and to select the desired status or setup screens. To call up the MHz screen, press and hold
and simultaneously for three seconds.
