MF0123A1F_FCC_uc Manual for PSR 700/800 MHz
5.6.8. General RF Setting
Band Selection: If the Feature Key ID is dual-band (as in the example below) both the
700 MHz Band and 800 MHz Band can be selected. If the Feature Key ID is single-
band, you can select either the 700 MHz Band or the 800 MHz Band. Only the items
corresponding to the Feature Key ID, including RF Settings, are Active.
DOWNLINK / UPLINK:
Band: The band to which the settings in this line correspond is displayed.
Gain. This parameter shows the current PSR gain (default setting is 90 dB): This value
can be reduced with the User ATTN setting (see below).
ALC: Use this button to switch ALC ON /OFF, however deactivating ALC can cause the
system to exceed allowed FCC levels.
HPA: Use this button to switch High Power Amplifier ON /OFF. If switched to OFF, the
entire band is deactivated.
User ATTN: The PSR gain can be reduced by 0 (= default) to 30 dB in steps of 0.5 dB
to a minimum value of 60 dB. For additional adjustments per channel see
chapters 5.6.10 and 5.6.11.
RL Threshold: The return loss threshold used for the VSWR Check (see chapter 5.7.5)
can be set in the range from 0 to 30 dB.
Broad Mute Level: Set the UL mute threshold level [broadband] (-105 to -60 dBm).*
Narrow Mute Level: Set the UL mute threshold level [narrowband] (-110 to -60 dBm).*
* If the UL input power falls below the set threshold, UL squelch/mute is activated. Default is -105 dBm
for broadband channels and -110 dBm for narrowband channels (Class A only). For Class B type units,
the whole band will be muted. With UL squelch/mute active, the UL gain is reduced by 30 dB. With the
Mute ON/OFF button, muting can be generally deactivated/activated. The button indicates the
currently chosen muting status.
Once you have finished RF setting, press the Save button to change the settings.
Analog Band Selection [Class B]: (only available for
analog Class B variant): The 800 MHz passband can be
set to 851 - 869 MHz, 851 - 861 MHz and 851 - 854 MHz.
