TXGAIN [ON/OFF]
This command enables or disables the transmit audio boost for the transmit
audio level. Entering the
TXGAIN
command without a parameter shows whether
the audio boost is
ON
(enabled) or
OFF
(disabled). Entering the
TXGAIN
command followed by
ON
enables audio boost; entering
OFF
disables it.
TXLEVEL [–20 to +3, AUTO]
The
TXLEVEL
and
RXLEVEL
(page 39) commands are used to control the audio
level settings when using the analog mode. When used alone, the
TXLEVEL
command displays the transmit level in dBm. Entering the
TXLEVEL
command
followed by a number from
–
20 to +3 (inclusive) resets the audio level in dBm.
Entering the
TXLEVEL
command followed by
AUTO
causes the transmit level
to be set automatically.
UNIT [10000–65000]
This command sets or displays the radio’s unit address, which uniquely
identifies a single radio within a network. It is used primarily for diagnostics.
When the radio first powers up, unit address is unprogrammed. Unit address
can range from 0...65000, but can only be manually programmed from
10000...65000. (Addresses in the 0...9999 range were assigned at the factory.)
6.4 Configuration and Programming using the
Front Panel
If a PC running GE MDS diagnostics software is not available to connect to the
radio, the front panel display and controls may be used to review and change
operating parameters and perform diagnostics. This section explains how to
use the front panel controls and screens. Cross-references to the corresponding
PC-based commands are included.
The front panel display has two modes: “safe” mode (display only), and
configuration mode. These modes are changed by defining the user access
level. When the radio is powered on, the front panel display is in safe mode.
The front panel display mode, and the brightness and contrast of the front panel
display, are the only changes that can be made to the radio in safe mode. The
front panel display reverts to safe mode after a period of time has elapsed
without a button press, whenever the radio is powered back on and whenever
a switchover occurs.
Normally, if no button activity occurs for one hour, the LCD display reverts to
a power saving mode. The only exception is the Operating Status screen. This
is a special screen, found under the Diagnostics main menu. This screen
displays key status, rssi, and SNR (if applicable). The screen does not time-out,
and is preserved during power outages and radio switchovers.
Changing the front panel display to configuration mode is described in
“Switching the Front Panel Display to Configuration Mode” on page 48.
