IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Installation
47 03/12
Reloading Factory Defaults
Desk sets are shipped from the factory with default settings that meet most installation requirements.
However, it is important to verify that these parameters are adjusted to meet your specific installation
needs.
To reload factory defaults, enter the Main Diagnostic Selection as described above. After entering this
mode, press
CTL
+
VOLUME
Up. The unit will automatically reset and show that the parameters are
corrupt. Follow the instructions on the display. For some models, this may happen twice.
N OTE : If your unit has been programmed with CARD Suite software, reloading the factory defaults will
reset all parameters that have been programmed.
PB1 – Line Output Adjust
An ac voltmeter or SinAdder meter should be connected across the line to achieve the proper level
setting. Ensure that the line is terminated with a 600-ohm load.
After entering the Main Diagnostic selection mode, press the
PB1
button. The display will indicate the
current setting, which is set at the factory at −10 dBm. The range for this setting is variable from off to
+12 dBm. See the Line Output Adjustment table for approximate settings. The desk set buttons are used
as follows in the Line Output Adjust mode:
Button Line Output Level Adjustment Mode Function:
VOLUME
Up Increases the output level, verifying the proper level with the meter
connected to the line.
CTL
+
VOLUME
Up Increases the output level by 10.
VOLUME
Down Decreases the output level, verifying the proper level with the meter
connected to the line.
CTL
+
VOLUME
Down Decreases the output level by 10.
TRANSMIT Saves the current setting and exits back to the main selection mode.
MONITOR Restores the previously programmed setting.
IC Exits the line output adjustment mode without saving the selection, but
maintains the current setting until the power to the unit is cycled. This is
useful for experimenting with different settings.
Using a communications service monitor/analyzer and a tone generator/SinAdder, connect the analyzer to
the radio base station antenna port. Inject a 1000 Hz tone into the input of the tone remote adapter
(simulating console). Manually key the radio and adjust the level of audio signal to set the audio
deviation of the radio to the desired level. Note the level of the tone, and using the Line Output
Adjustment Table below, program the desk set to the closest level.
