MGC DIP SWITCH CONTROL FOR
The Uniden U4P DB-CP allows you to manually attenuate the db gain of the
device in increments of 5 and 10 db with a maximum of 15 db.
On the back panel of the device you will see eight dip switches labeled 1 through
8 which are broken down in four sections as follows: DL2, UL2, DL1 and UL1. Each
section represents 2 dip switches (See image on opposite page).
HERE IS A BREAKDOWN OF THE DIP SWITCH
SECTIONS
The first section is labeled DL2
and represents dip switches 1 and 2.
These 2 dip switches control the downlink of the 1900 MHz frequency. Dip switch 1
represents a 10 db reduction and dip switch 2 represents a 5 db reduction.
The second section is labeled UL2
and represents dip switches 3 and
4. These 2 dip switches control the uplink of the 1900 MHz frequency. Dip switch 3
represents a 10 db reduction and dip switch 4 represents a 5 db reduction.
The third section is labeled DL1
and represents dip switches 5 and 6.
These 2 dip switches control the downlink of the 850 MHz frequency. Dip switch 5
represents a 10 db reduction and dip switch 6 represents a 5 db reduction.
The fourth section is labeled UL1
and represents dip switches 7 and
8. These 2 dip switches control the uplink of the 850 MHz frequency. Dip switch 7
represents a 10 db reduction and dip switch 8 represents a 5 db reduction.
The Uniden U4P can be reduced by 5, 10, or 15 dB. When a dip switched is
moved up to the ON position it will implement a reduction for the amount of gain
indicated. The left dip switch in each section will reduce the gain by 10 db and the
right dip switch will reduce the gain by 5 db. In order to initiate a reduction in gain
the dip switch needs to be pushed into the “ON” position which is up. So to reduce
the gain by 10 db you would move the left dip switch in the respective section up,
and leave the right dip switch down in the “OFF” position. To reduce the gain by 5
db you would do the opposite, meaning you would keep the left dip switch down in
the “OFF” position and push the right dip switch up in the “ON” position.
In order to reach the maximum gain reduction of 15 db, you would push both dip
switches up in the “ON” position.
